Underfell Sans Boss Fight *GENOCIDE* | Deltatraveler [ DELTARUNE/UNDERTALE FAN GAME ]

[@xsl]

By the way this fight only really changes at the end so keep that in mind *FULL OBLITERATION ROUTE* : kzbin.info/www/bejne/e3iuemSJrcSpm9E *ONLY SECTION 3 GENO* : kzbin.info/www/bejne/lYi4iImXj8Sqgsk *PLAY NOW* : gamejolt.com/games/deltatraveler/661464

[@thethundercat2943]

I love how Deltatraveler has multiple references and scenes from the original UnderFell animations. Such as the mail that tried to kill the player using bones. Underfell papyrus not being a completely edge lord and only pretends to have malicious intentions, but actually is still a nice goofball that loves puzzles. Not to mention, when Sans says, "I'm gonna have a great time." the font changes to the original "Vs Underfell sans" video. Props to the devs!

[@justme-u1q]

Same here

[@latte876]

@@r0z557 It's from Undertale

[@gachax5703]

Also how UnderfellGG wich is this version still retains Underfell Sans' "Great time" instea of Bad time lik undertale wich is something i found quite nice

[@_abowlofcoke6553]

it's because they're made by the same creator so the section is suppose to be an exact replica of the original with a few tweaks. As for the font, it's just a thing from og undertale where the font stops being comic sans when sans says "should be burning in hell"

[@gachax5703]

Also idk if anyone noticed but a lot of Fell Sans' attacks are taken from another fangame made by RynoGG/Sarah wich Is skeletal vengence

[@Pablo-4048]

This sans really is flowey. "This world is kill or be killed" and being brutally killed swell.

[@Tumeton]

@@godofhyperdeath2016just flowey in general.

[@youyououmf8200]

In underfell, Flowey's view of the world and the world's rule are switched. In underfell, it's killed or be killed, and flowey don't want that.

[@Zimbabwae1]

​@@godofhyperdeath2016 not really since Undertale yellow flowey decided to trick clover into going to asgore instead of straight up killing them but there were probably runs where flowey just got angry and killed clover out of frustration like in neutral

[@KirbyGamerEX27]

6:03 so it CAN hit sans with a perfect bluster HIT

bro i didn't even notice that i thought he was still distracted LOL

[@AmatsuneS2]

Yeah and other party members can hit him aswell after perfect hit

[@actuallyeli8768]

@@xsl he also can get hit without that i think i saw a video of somebody using rude buster into iceshock where he returned and took damage so i think with precise timing you can

[@overheavendio5665]

TBH out of all the sanses that were created, this has to be the most pure evil one.

[@kauedasilva1072]

There are ways to avoid Susiie getting Devious. The first way is to make sure to pick options that sound like something Kris would say, AKA not the rude options.

[@KrispBacon518]

Dumb question since jerry is a secret boss does it matter if you kill him or not? So if your on pacifist would killing him put you on a neutral route?

[@lucas_19486-Intruder]

For the red buster thing, I think it lets you do red buster, but susie can sabatoge you. When she has a shadow over her eyes, she wont attack or use rude/red buster.

[@quentonfrancis2616]

No, it will always be sabotoged to hit you.

Nope, if kris state is deceiful always will hit you even the game say it

[@8lFx]

Kris: Susie, obliterate this man. Susie, feeling a bit devious: Nah, I’d sell.

[@icelingbolt]

Fun fact! Only in genocide does sans deal Karma damage, which doesnt happen in pacifist

[@jarydgrobler9526]

He actually also does this in neutral. I only killed the end bosses of the first two chapters and he dealt KR damage surprisingly

[@BrodyDokkan]

I mean, that still would count as karma... bad karma.​@@jarydgrobler9526

[@legendary_wolfy9223]

Because kr happens only if you have LOVE

[@_Ceetu_]

@@legendary_wolfy9223 which is weird considering it was never stated in canon to be based off your LV, the interpretation mainly stemmed from its name when it could just be a general status effect he can dish out, but its cool. adds more depth to his character anyways instead of just being plain poison (in normal undertale anyways, i wouldnt call gg! underfell sans much of a judge)

[@oscarpro8349]

​@@_Ceetu_ he isn't a judge, he just wants to kill you (even if you haven't killed anyone), btw, canon sans just waited for you to get to max lv to kill you easier (he is a judge)

Notice how Fell still retains Sans's main weaknesses - laziness,predictability,and close to no actual defense.

@@tracey8121Well.. in this world he has been killing alot so his stats would end up getting better as a result i think. If i recall how it went with Jerry at least

[@JacksonVoet]

His greatest weakness is his mental state really. Due to his ever degrading sanity, he can barely focus enough to dodge, and uses attacks that are far more showy and brutal without accounting for real difficulty due to his bloodthirsty overwhelming his calculating nature.

Damn that ending is brutal I guess temu sans deserves that after all he acted like FLOWEY he gloated about killing fell suzy i mean he practically dug his own grave And I thought quiet people pissed her off

[@SolsLuminous]

I feel like it goes both ways, very quiet people piss her off, but sadisticly loud people piss her off more

[@CROWNEDDOOMER682]

@@SolsLuminous This makes a lot of sense I was only going off of her dialogue but thinking about it this all makes a lot of sense at least quiet people are not nearly as psychotic as fell sans here he said that on purpose to piss Susie off I think I like the ending where he gets frozen seeing as he seems truly sad here he doesn't go out laughing he goes out sad and while normal sans is one of my favorite characters ever fell sans has lost all redeeming qualities so the ending that he is most sad and unable to laugh and piss off Susie more it's the best ending
