The hidden world felt like a perfect ending for the franchise. We had the tv shows to fill in gaps and time and we watched our main characters grow and move one with their lives.

Fr it’s unbelievable for someone to kill off a whole species of animals meaning that there could be some more night fury’s hiding out at the hidden world.

[@capricedowsland3068]

Number one I agree: I doubt he could've killed them all and I think there may be more night furies and light flurries out there that stayed hidden and they never saw. Humans love to exaggerate about everything especially about their kills. Two it is very dangerous and could cause deformities but it could happen and most people would not even see the incest of it because it is not humans doing so it is animals. A lot of dog breeders breed dogs back to fathers or grandfather's or go the mother or grandmother route occasionally to double back up on certain genes, tho mostly outcrosses are preferred. Third it is just a movie no reason to trip out like it is human porn. Good gawd!

[@estevan764]

Obviously not lmfao, Grimmel killing all of the Nightfurys was never even said. Every dragon trapper played a part in the extinction of them, as well as the vast majority of them probably never having located the Hidden World and lived in nests led by a single alpha (example being the red death of where Toothless originally resided).

[@jimincafe335]

Honestly I rlly don’t believe Toothless was the last of his kind. Toothless, from the beginning, seemed to be very intelligent, extremely strong and vigilant, it’s likely that night furies are naturally like that cuz toothless was mostly likely left alone at a very young age since it didn’t seem like he was taught how to properly perform a mating dance. The book of dragons never had any info on night furies so it means they’re so elusive that barely any one has gotten a proper look to record in the books. There is a possibility that toothless isn’t the last night fury, they’re extremely intelligent, can cloak(they mostly knew how to do that, but again since toothless was probably left young he was never taught that before) so elusive that for hundreds of years there’s been no record of a night fury. Come on people let’s be honest, how believable is it that Grimmel was able to hunt down EVERY SINGLE night fury other than toothless. It’s rlly possible that there were night furies hidden in the hidden world.

[@playerjack2566]

Night fury are like black Panther can be seen in decades but are there

[@remyandcoco9490]

I do approve of this theory because this has actually happened in real life with a fish dubbed a coelacanth. This extremely rare fish was thought to have been extinct for millions of years because nobody had seen one until 1938 when a live coelacanth was found deep down in a cave somewhere by one of those underwater-deep-sea drones.

[@nightshiftthedragonshifter6562]

I completely agree. There is no dark secret. Just because we haven't seen other Night Furies besides Toothless in the movies doesn't mean that they aren't there. For people to think that the reason the Furies in the future are around based on incest is just sick. Give us actual legit proof, REAL proof that we are wrong. You can't because it ain't true.

i want to add to this that in the original books the mosnter dragon from the firs tmovie actually was the same species as toothless .. so straight from the beginning he never was the last and it shows how powerfull these dragons can be. Later Toothles became a great leader himself actually. Also about the lightfury .. we never heared of them or saw them before and grimmel was just like 'here look these axist actually' so if light furys, a related species can hide that well that noone knew of them then nightfurys can just as much do that too !

I honestly don't see it as a full fury. It could very easily be a hybrid with another dragon. Maybe a dragon that already has a black and white pattern, or one that would be recessive to the colour of the nightfuries.

Dragons are intelligent after all.

[@PeachyLover007]

Well, concluding that the dragons in most of the movie lives up to hundreds of years, but less than 500 years, average 300. And toothless is hiccup's age, then maybe he might have bred with other light furry's its a possibility, to keep the species going.. plus he is the new alpha, so it can be expected to keep the lineage living, they would breed with cousins or distant cousins for next in line... its another theory i made on the spot just now lol so its not that backed up..

[@remyandcoco9490]

You do have a point but if you look at the features of the dragon in the nine realms it looks drastically different than toothless , that kind of adaptive change in animals takes much longer than 3-4 generations of dragons.

[@MegiMoon]

Or Toothless and Light Fury had kids multiple times. Not just the three Night Lights we know. Also possible that since Toothless is an alpha dragon in Hiden World, he would get into mating with other Light Furies there. It would still lead to some genetic problems but not as much.

@@err2900 If just one partner then he wouldn't mate with Dart and just do stuff with his Light Fury. Also Night Lights would stick to just one partner and then species would die out which didn't happen. Possible that survival instinct kicked in Toothless so he mated with multiple Light Furies to preserve his species. Also possible that he mated with other Light Furies because it's potential alpha dragon rule so Toothless would go around having just one mate rule.

I agree. When they said last of their kind it was the last known of in the human world. With an entire hidden world of dragons, it's possible there are more night furies. Also their tales and styling looks different. I wouldn't be surprises if other species of dragons can cross breed successfully. There may have been a few other similar dragon breeds that they had families with. After all it happens in the human world where we think a species is extinct and then we find a hidden population thriving somewhere previously undiscovered. I think this series would have been better if they went with that storyline showing that there were still night fries, light furies and Toothless's blended family

I believe that this is also a very good possibility! Great theory!

Not only that but the other dragons too. I'm betting on evolution. The Chinese model inspired dragon has two heads and looks like a zippelback, the dragon with the crystal horn (I'm gonna call it a crystal rhino) has a tail bludgeon like a gronkel, definitely boulder class, the teel dragon kind of looks like a nadder, and as you said, the fury design looks like a cross between a nightlight and a sand wraith.

My stomach churned when you brought up Toothless and Dart mating. All they had to do was make a light grey Fury. That's all they had to do. Maybe have some of the NF nubs, but have it mostly be LF. That's all they had to do. I think the premise of the show shits all over THW anyway, and will likely just add more to the toxic environment of the fandom. It is just a dumb idea. Should have been the Haddock kids as adults with their children, or the Berkians today, protecting THW. How cool would that be, the Berkians protecting the secret hundreds of years later, and spreading the legends of the dragons, fully integrating it with their culture and fighting for environmentalism. It would be timely and epic, and when a crisis happens where both parties are in danger, they prove their loyalty and decades long bond by saving each other and the world. God it would have been so bad ass. But nah pug dragon it is.

If you look closely in movie three, you can see that more light furies exist. Also, considering the fact that the Hidden World is so vast and the new series introduces another smaller version of it, we can assume there are different hidden realms and night furies possibly existed too. Whether this means Toothless breeded with every female in his Hidden world colony or the night furies and light furies were brought together by some geological disaster, that would be interesting to speculate, but I doubt that all of them are extinct especially since the third movie reveals that there is so much more to the world than Hiccup can see.

I have a different theory, I think Grimmel didn’t kill all the Night Furies. I believe that all few remaining Night Furies found their way into the hidden world and started mating with the other Light Furies, therefore having Night Lights of their own. So I’ve reached the conclusion that Toothless and his wife did not breed with their own children, but in fact that their Night Lights and the other Night Lights began having their own children, The Fury Dragons. Plus I think it’s worth mentioning that because of the fact that the Fury Dragon is a direct descendent of the Night Lights (which are hybrids between a Night Fury and a Light Fury) who has mixed DNA from two similar yet different dragon species and spent so much time underground, which I’m lead to believe that evolution took a slight turn therefore why this Fury Dragon’s Physical appearance (not talking about its colors) looks a bit different from the original Physical appearance of the Night Furies, Light Furies, and the Night Lights. So there was no inbreeding/incest involved. You’re welcome, now you can sleep at night.

[@ladyriptide2523]

hi, im a zoology major, there are....some serious issues with the genetics in this video, especially the information about inbreeding, just wanted to make a few points. Inbreeding doesn't always create immediate horrific health consequences. in fact in isolated populations it's very common (see the founder effect, which occurs when a small population of a species collonise an isolated location, like an island). It is detrimental, because when closely related organisms reproduce it reduced the gene pool of the offspring, this means that they're less adaptable to changing enviroments, and also have a higher chance of becoming homozygous for detrimental, recessive alleles (recessive genes only affect the individual when there are two copies, requiring both parents to carry them and pass them on). The easiest way for this....nightlight....thing, to be the colour it is is if the gene that's causing the black colouration in Dart and her brother is dominant. This would mean they have a 50% chance of passing it on to offspring, so it would be easy for it to remain in the population without the need for inbreeding. Given the litter size for night/lightfuries seems to be 3, Dart and her brother have a pretty high chance of passing it on to at least one of their offspring. Though given how they're all kind of sealed in a cave....inbreeding is inevitable. Especially since there only seems to be a few other lightfuries around. One more thing on the cat genetics, the way it works is that the gene that codes for colour (specifically, wether the cat produces red or black pigment - pheo or eumelanin if im not mistaken) is on the X chromasome, thus we say it's "sex linked". The Y chromasome is what cannot carry this information. Not the XY combination. Thus Male cats can either be Ginger or black, and not tortoiseshell unless they're XXY, a chimera or have a somatic mutation (essentially a birthmark). Male cats can't actually pass on this information to their sons for this reason, and while they can pass on other colour information, like tabby genes and colourpointing like we see in siamese cats, the male offspring of two cats will always get his red or black colouration from his mother. I understand the video wasn't supposed to be too serious and it was a fun watch! just wanted to clear some things up because genetics is a passion of mine, unless the black colouration is caused by a dominant gene it is seriously weird that the fury dragon is black 1300 years later though, and you are absolutely correct that in order to get that phenotype if dominant genes weren't in play you'd need some serious inbreeding that would reduce fitness and the chances for nasty deformaties so badly that the thing should absolutely not be alive. Also, if we were looking at an all black individual or a nearly all black individual you are correct that the most likely scenario to get that would involve repeated inbreeding between toothless and dart and amongst their offsrping, in fact this happens a lot in purebred dogs and other domestic species that have desirable traits breeders want, unfortunately. It's irresponsible and bad for health, but it won't immediately create mutated or diseased individuals, the chances of that happening just increase more with each inbred generation.

It was a long time ago, but I want to say. Because Toothless was strong enough to be the only one left of his kind, his genes could be much stronger than 50%. In addition, he is considered the leader of all dragons, so, most likely, his children have somewhere between 75-80% of Toothless's genes. There are many day furies in the hidden world, so it seems that their genes are so strong that they completely eradicate the black color and some other features. At least I want to believe it :(

Considering that the dragon in the trailer has a drastically different tail and slightly different head shape than both the night fury and light fury, it is possible that there are other dragons in the mix or it may be a different kind of fury altogether.

[@shinigamis_like_apples4797]

You do know that although toothless was the Last Night fury, the light fury wasn't the only light fury, right? Toothless kids probably had offspring with the other light furies, and since the black color was more prominent, it carried through the offspring and many generations.

[@BRØmenValorant]

[@arteria.coronaria]

Well, this is fundamentally wrong on a genetic level. You correctly recognized that the traits aren't linked to sex, which is good. About the rest- you forget about heretozygous individuals and the fact that all beings need the genetic set at least doubled to function! If the genotypes for furies are dominant white (W/W, keep in mind all animals must have at least two sets of chromosomes) and non dominant black b/b , then all the kids of toothless and the light fury would be heterozygous! (they have a copy of Black and a copy of White each, so W/b.) If white was dominant, all the offspring furies would be white, which they aren't. What we see instead is a so called intermediate Phenotype (Phenotype=Traits by looks). This makes sense because in fiction just as in nature, usually multiple genes are part of defining skin/fur tone. In humans that's over 20 genes we know of (and we keep discovering new ones!) If you are still worried about black furies disappearing as a colour, there's no need to because if the kids happened to breed again (be it with eachother or with other furies), they still carry one gene coding for black! If they happen to reprouce with another fury that is heterozygous like them (aka W/b), or a black individual, black offspring will show again! Please do not spread misinformation like this and please do pin a comment like this explaining the whole misunderstanding. As for incest- happens way more often in nature than we like to think it does. It does show an overall very negative effect on a population if it occurs, mostly because diseases are usually recessive (you need two copies of it so that it shows in the phenotype), so things like birth defects show way more often. However, I still think from a biology perspective this is way better than you know- dying out as a species. I am open for all types of questions or explanations if any are needed, I get that genetics can be tricky at times (after all I study it so...yeah....). It does seem a bit like a clickbait title with misinformation content (especially to a younger audience who cannot tell), hopefully you can elaborate further to the audience!

[@hedgehogsx2396]

I actually commented and said that I'm OK with the fact that they probably had children together. It seems like something that would happen in nature, plus, it's not like... Well.. In real life, dragons have self awareness. It's not like they know they're mating with their kid. They're just mating with an available carrier. Seriously, they don't care. If that's all there is, they'll make it work. And the fact that a black baby could be born again was on my mind since the third movie, thank you for touching on that.

There is one problem with this theory that is also pretty dark, Toothless could have breeded with the other light furies. we see 3 other light furies in the movie and if each has three children like toothless and the light fury that would mean 9 children + the first 3 meaning 12 children that could have also breeded with each other.

2:34 The blue eyed black nightlight dragon, looks like the one in the new series. Dragons, from any mythology, live longer than humans. The oldest dragon in the how to train your dragon book series is 1,000 years old. By the 3rd movie, toothless is 21. And, who knows how long dragons stay in eggs for, all dragons are different. In the end of httyd 3 , toothless is 30. Meaning his kids, are 9. So 9 + 1,000 = 1,009. But, if we take into account how small they are at age nine, we can expect them to get even bigger in the future. So what if, they go into a state of hibernation. Where they don't age, or do much. They eat every hundred years and stay alive that way. Same way as bears hibernate during winter, but longer. Like, we don't know much about the dragon world. Only what is taught in the movies and book series, which the movies are based off. So, in conclusion, incest isn't the answer.

This was also the movie where we’d found out Meatlug was actually a girl too.

Oh my god XD when I saw the new nine realms dragon I just thought "hey, thats genetically impossible, there are no more night furies, the black color would've faded away centuries ago if they kept reproducing with light furies" but I hadn't thought about what this dragon's existence actually means lol Honestly, yeah, pretty disappointed the creators of this show went with such a weird, non-scientific approach, in this franchise that basically praises the scientific method. Couldn't they have made the main dragon a different fury? I mean, sand wraiths seem to be pretty similar, I'm sure there are more furies besides night and light furies, they could've went with a new dragon that looks like a hybrid of furies we don't even get to know, but they went with the easy money alternative, making it a night light 2.0, sigh...

Another theory would be, that toothless color genes just happened to be, because he's melanistic. So that would happen to give every of his offsprings a chance to get a slight part of his color. Maybe I'm just talking bullshit, but that's what I learned in biology, lol

There are a lot of species that never have been mentioned, solely due to the length of movie and lore, in the first movie we saw that their knowledge was extremely limited, then in the second? More than doubled, tripled even. moving on from there we can infer that there are likely other dragons like toothless. "Last of his kind" is next to impossible, given that up until the first movie, they never seen a single one. Grimmel said he killed them all? But that also isn't possible, because they can hide super super well, older night furies must have existed, I doubt all of em died. All of this is just speculation as we don't know until it is explicitly said by the director, not by the characters as suspense or "plot". Assuming they lived, we can also assume a few light furies lived too, if you watch the last bit of the hidden world, you'll see that there are other light furies, they are clearly a deviation from the night furies, design choice or something else, you can decide. So their genes are compatible but also different. Onto the night lights, they inherit bits of traits of both, besides colour. This is the actual part that is worth reading lmao. They would've stayed under ground for a long long time, so we can assume they had more children, and we can also assume that some light furies mated with other light furies, in turn we can also assume some light furies also mated with some night furies. At this point we can assume that the night fury gene would be filtered a bit more, however its never said that they can't breed with other dragon types, its been pointed out that the tail looks like a sandwraith. Even if they can't, darwins principle applies, survival of the fittest after all, meaning that through time there would be selective mutations in order to fare better, the weirdly shaped head and a more prominent nose could be due to needing to scavenge and forage more, all the while staying out of sight of the humans. Besides, it's a kids show, they aren't going to loop in incest, or toothless mating with his child, thats just absurd.

The scales on the other fury species are more smooth and suited for speed (much like dolphin skin and shark skin) while this one looks armored and more durable for taking hits- There could be a combination of breeding with different similar species of fury as well- Like the sand wraith, that species does have a similar design to this dragon and without knowing how long dragons live for if in the perfect environment the color gene could still carry on being the black and white that the night lights are-

So in the movie it notes that Nightfuries, and I believe light furies, take one partner for their whole life, meaning toothless and his mate would have never touched their children. We also know that lightfuries were not whipped out as you can see two of them in the hiddenworld. We should also note that siblings are not completely genetically similar. They are close enough that it can cause issues, but usually they have enough genetic differences to not cause huge amounts of issues. Keep in mind each child have a 1/4(or more depending on the dragon genes) to have similar genetics to their parents. Now this could lower if both parents are homogenous in any of their genes, but the point still stands. It is also clear that the white gene is a submissive gene as only 1 of their children was remotely all white. Which hints to there being more genes used in making of night and light furries, as toothless has to carry a gene more submissive than white. Anyways, this means any dragon coming from 2 of his offspring have a 50% chance of being black, which means in theory that 2/3s of his family tree branching from him will look similar to his two children. We also know that the man, can't remember his name, clearly wasn't thorough on killing all of the night furies and it is safe to say that nightfuries survived in other parts of the world. To top that off they all thought the world was flat so likely didn't travel far enough to kill every single one. Meaning that as Toothlesses' lineage spread out they would have come across more nightfuries, and most likely lightfuries, to further the new breed. My last note is that this new fury has a different build than the nightlights and their parents, so it is highly likely that they breed with a different dragon species that could make fertile offspring and/or they found other fury breeds with slightly different builds. 1000+ years isn't really a long enough time for what seems like a long-living species to evolve that much without the help of other species/breeds. All in all, I don't think they inbred anymore than they would have if there were larger amounts of them. However I do think that this dragon is hinted to be related to Toothless and one specific offspring due to her patterning. Because movies always use things like that to tie two characters together. Also sorry this is a lot, I have an obsessions with nerdy things like this.

[@casseroledragon3277]

While I love the work you did on this video, you can see other Light Furies in the Hidden World, so the Night Lights could have bred with them easily, and color genetics don't work quite as smoothly as you're suggesting. DNA doesn't work at a smooth 50/50 ratio, and Black scales would likely be a dominant gene, and therefore be more likely to pass on to their offspring. I also think that, though they never show it happen in the series, it's likely they bred with other dragon breeds. That would explain why the dragon in the Nine Realms has a different body shape and wing shape. His chest is much broader, and his wing membrane doesn't go as far down the body. 😅 It's a neat theory, but it's way more likely that the black scales are just dominant and therefore became more prominent than the white over the years, and breeding with other quadrupedal dragons led to the changes in physiology.

[@vd6070]

Not to mention that Black Scales in terms of survivability are far more valuable considering Night Furies hunt at night, and on top of that the hidden world is a much darker place. So it's entirely possible that the Black Scales, in an environmental, evolutionary and genetic standpoint are considered far more valuable. I wouldn't worry too much about the genetics of Toothless and the Light Fury's kids though, and moreso on *what will they all eat down there.* Now THAT is a talking point on what food they actually have available.

Even if we are assuming that toothless is the last night fury and there aren't anymore hiding in the hidden world it was never mentioned that she was the last light fury. So toothless's kids could grow up and mate with other light furys carrying on the night lights color pallet especially if we assume that the black is the more dominate trait.

[@silk.and.cologne]

i mean, it could be possible that toothless and the light fury had more than one clutch of night lights in the future, and that each of the night lights bred with another light fury (not their mother though-) which would create the chance of having the black gene. don’t quote me on this. please.

[@fluff1694]

even when drago and grimmal assumed that they killed (almost?) every night furry, toothless was still alive. meaning there could be more species of night furrys out there, just not in that location…as well as not many people even knew about the hidden world, so some of them could be living there like the light furrys

[@cryptidkisser4276]

This was one of my first thoughts when I saw the teaser 😭

[@b3nnefits]

Well, if you think about it, Toothless couldn’t have been the last of his kind. Grimmel said he killed them all, but that was only in a small part of the world. There could possibly be whole colonies of night furies, though I doubt colonies since they are probably loner dragons, like the skrill and possibly others from that dragon class, the dragons probably spread out, for all we know this isn’t Berk (though it most likely is) Anyways, this is a cartoon so I highly doubt there would be any actual incest and they just didn’t think into it.

[@Izuku_Midoriya_No.1]

I agree, it's entirely possible that there were other Night-fury's that we just never got to meet, or see. It's also very possible that they simply have longer life spans, we might not be too many generations in for our fury family.

[@cheyblake2475]

There is a video by Alteori explaining that Toothless might not be the last of hos kind. She explained that if Toothless can turn invisible like the Light Fury, then other Night Furies can do the same too, which means that there's a possibility that they are still more of them, just not much as there were a long time ago.

[@cyrianredfoxveno]

There is something else that needs to be taken into account. Has there anywhere in the HTTYD universe on how long dragons can live for? Also is it possible there is more than one entrance to THW? Because I agree with another commenter that I don't think it's possible that one man killed all of the nightfuries. Maybe in one location but I just don't think he killed all of them.

[@Izuku_Midoriya_No.1]

Agreed, and no, it was never confirmed how long a Fury lives, so It's very well possible that we're not too many generations in for the Fury family and if the color does fade over time, we haven't gotten there yet.

There is a problem with this though… in the Hidden World Grimmal the Grizzly says that The night/light fury species mate for life so it’s HEAVILY unlikely that any of the og nightlights mated with either of their parents… but the nightlights breeding with the other lightfurys is a possibility and because 3 is the average number of offspring per litter (also assuming that after one set of offspring leave the nest another set is born from the same parents who usually live to 180+ years) it’s easy to assume that the gene pool does stay fairly large for at least a couple hundred years!

[@MischiefLord777]

I have taken your theory into consideration, however I do think it is also possible that the nightlights bred with skrills. After all, Thunder doesn't fit the exact body definition of the the Night Lights we're used to, plus there's the issue of just...developing proper power over lightning. Toothless could only use lighting when there was a storm overhead, but the Skrills just can shoot lightning as seen in RTTE. Not to mention from the Skrills we've seen, the very few admittedly, they seem to be dark in color.

[@lizkhaylin2141]

True, but considering many real-life animals get sterile hybrid babies, then there’s got to be more generations in order for Thunder to actually exist 1300 years later. And that’s considering their max lifespan is 100~, but I hear dragons are supposed to live longer than humans so, 🤷🏼‍♂️.

There is a theory that night furies and light furies come from a different part of the world which explains why toothless was the last known one seeing as the people of berk don't know much about other continents.

[@absolite6]

This brings back to the time in secondary school when my Biology teacher basically said one lesson "Right then, today we are going to learn about the disadvantages of incest!"

[@Swiftkill416]

According to wiki dragons from the lore of HTTYD can live to a span of 200. It's not impossible to think toothless had alot more than 3 kids and they bred with the other light furies and some genes could very well be a mutation.

[@UltraInstinctShaggyNO.1]

This isn't necessarily true, as there is still the possibility of rare mutations within the dragons. Not to mention its all down to the chance of what colour the dragons will be, as its not a garenteed chance that the dragons will be a set one colour. Because that is how genes work, a scale colour gene can be passed throughout tones of generations without any show, but the gene will still be within the DNA of the reptile. Which means the later generations of toothless' line will still have a chance to show black colouration (even if the chance of it happening is very slim) Yes, maybe the dragons did commit incest. But that is a very slim possibility as in the wild baby reptiles are abandoned when it is able to defend itself from predators (about the time when their hormones kick in, basically puberty) And I would like to think it's the same for dragons. This might be very difficult in the hidden world as it is a limited space, but it is still their instincts for the parents to separate from their offspring. And for the offspring to find a mate of their own, and continue the line. So before you go ruining children's films, make sure you know all the information, rather than a small bit of it and ramble on. For example, I have just stated facts, and leaving it for others to infer what they think with these facts.

[@CoffeeGuy2090]

Or possibly toothless daughter used I think it’s called parthenogenesis which is the process of when a reptile basically clones herself in a egg which could explain how night furies still exist.

[@yumisxs5952]

The chance of Toothless being the last of his kind is somehow possible but really low, look at how big world is, i'm sure that Grimmel missed some Night Furies, so if we think about maybe something like Night Fury island really far far away from the places Grimmel can reach, a place where the Night Fury species is doing very well they could also go to the Hidden World but maybe with another entrance to it and live there, somehow between other dragons, and one of the night lights also could have offsprings with one of these, keeping the bloodline normal. Or, if the Light Fury is really a separate species instead of Night Furies who lost their black pigment due to no sunlight and etc etc there already should be night furies in the hidden world already, even before Toothless gets there, and one of the Night Lights also was able to mate one of these. Yeah, they mention a lot that Toothless is the last one of his kind, but somehow i don't really believe it - the world is big and we don't know how exactly big is the Hidden world also. That's just what i think, but the theory you said about Thunder's lineage is also possible, sadly.

[@archieoutdoors3340]

Yeah, if dean ever said ‘well no toothless is the last of his kind’ it’s just a lazy way to stop people asking him if there’s more, which there most likely is. I mean there’s literally a whole topic of *NIGHT FURIES IN THE DRAGON EYE*

[@lordcooler1703]

Well, if you think about it, since Dart (the female Night Light) is indeed a female and possesses the black color like her brother, Ruffrunner, then it's highly possible that if she mated with a male Light Fury at least a few of her hatchlings would be born with that black color. Personally, I believe that at least a few Night Furies besides Toothless managed to escape to the Hidden World. But that's just me.

[@dartskyee]

Yep, I'm a girl

[@requiem6775]

There is also the possibility that the dark gene is simply dominant over the light gene, and is expressed more. Phenotypes for things like hair or skin color are more complex than just A or B, but I believe that this idea might be supported by the fact that 2/3 of the Night Lights are mainly black.

[@torrentpath]

It would have been so cool to see Hiccup’s son or daughter bond with a Nightlight Fr why are we over 1,000 years in the future

[@omniverse7976]

I like to believe that the Nightlights had kids with other species of dragons in the hidden world and the fury genes and traits are just dominant.

[@hedgehogsx2396]

Like the sand wraith

[@thedodoking7385]

Well usually in lizards they lay more then three eggs and who’s not to say toothless didn’t have more children with the other light furies then those children had offspring with the other offspring from different mothers but we can’t truly say that he did or didn’t do that but I am exited to see the show

[@litcupcakeplant2189]

If we take a closer look at the new furie’s tail, we can see that it looks kinda weird I think that from the night lights to the nine realms (in 1300 years) the furies reproduced with other species, creating new hybrids To be more exactly, the new dragon has the head and the tail almost like the blue dragon from the rescue riders So the short variant of what I want to say is: maybe the future furies will reproduce with other black and white dragons, creating new and WeIRd hybrids

[@BruhTNT4258]

It looks like a Nightlight smushed with the tail of a Sculdron.

[@usedused1916]

The answer is simple : The creators had no intention of actually looking at this show from any perspective as it is just a poorly done show grasping at threads from the previous series, the 3rd movie was meant to end the series with an ideal ending rather than continue the plot with no actual research about simple high school biology and it really just goes to show. Me personally i cant even imagine inbreeding done by toothless as i am biased and i dont think the creator meant for it as well showing how little effort went into this (edit i would also like to add that the body structure is vastly different as the tailwing has a noticeably large spike on it which isnt a trait of either night nor light furies )

[@JordyanBWolf]

Genetics don't usually turn out to be a 50% type of thing in any given breeding situation unless everything is under "perfect conditions". The original 3 nightlights, breeding with lightfuries, actually do have a fair chance of producing another nightfury. Just not a purebread one. It's more of a Mendelian genetics type of thing than a normal 2x2 punnet square. Same thing with two ginger people with brown eyes having a blue-eyed kid even though both sides of the family are mainly brown-eyed except for some distant uncle that has been long dead who had blue eyes. But for there to be heavily dark colored "nightlights" this far in the future (maybe the dragons live longer than we thought I'm not sure) it very hard to have happen *naturally...* With the way the current one is built, there may be an easy answer to there being some insest to-- actually get this sort of outcome... which is upsetting...

[@Dragon_Racer_09]

Or the light furies find the darker black scales appealing and a nightlight with them is more likely to find a mate keeping black scales in the gene pool

[@vyperz6946]

Ok I have three problems with this 1. Toothless isn’t the only night fury. If you watched httyd 3 there are multiple light furies in the hidden world. In the first movie they stated that night furies owned the night meaning that there were multiple night furies. When you take into account the multiple islands such as Beserker, outcast, defenders of the wing, wing maiden, etc. the amount of night furies could add up to 1000. I highly doubt that grimmel and other Vikings could take down this many night furies considering their intelligence and strength. Plus if the night furies were on the brink of extinction they wouldn’t keep attacking the Vikings. We have seen with species such as the buffalord and dramillion, when they were on the brink of extinction they scattered to different remote islands such as dramillion island. So even if the night furies were about to go extinct they could always go to safe places such as the hidden world or vanaheim. 2. The colors of dragons don’t depend on who they breed with. We have seen in race to the edge that just because a dragon breeds with another dragon doesn’t mean their offspring will be a mixture of the two colors. For example, the singetails were forcefully bred by krogan but the singetails are always one color. 3. Toothless’s kids aren’t the only mixture of night and light fury. Night and light furies have been around longer than the Vikings and we can’t assume that toothless and the light fury were the first ever to breed together. Therefore one of toothless’s kids could’ve bred with another mixture of night and light furies. Honestly I respect your theories and I’m not here to hate on you. I’m just here to spread my thoughts. And also I have way too much time on my hands However I have to agree this series was a disaster. The fact that it took place 1300 years after the berk era makes me question what true were thinking. It’s almost like they wanted to restart but keep the same concept.
