I wonder if Sans fused with Error 404 and Chara fused with Infected

[@narrativeless404]

Infected+ Undertale Chara would be overkill for Error 404, and fusing with Sans wouldn't make him any stronger Error 404 vs Chara in True Form is already a stalemate, even though 404 is technically stronger. Giving that to someone like Infected would be a Death sentence for William Giving him a regular Chara, same kind of that Frisk has should still be more than enough Infected becomes Mix!Corruption if True Chara and Killer!Infected if regular Chara: this gives S/L/R access, unparalleled control of *DETERMINATION* and *HATE,* advanced adaptability, better code protection and destruction ability on top of what he already has, and amount of power increase depends on a particular Chara, as vary really extremely It's a sentient power up you nor anyone else can get rid of basically Error 404 becomes Admin!Sans: everything Error 404 has except not broken and completely stable - no new abilities besides the sanity and stability upgrade

[@Astrix304]

I thought so too, and that it was a fusion of two sans that were already fused once (2 x 2 = 4), those sans being [something to do with error 404] and [Virus 504 or something], but the "UnderTaleAu Gods Wiki" says this: "Omni404 is the creation of an enigmatic being only known as "The Game Developer". Omni404 believes that its creation was a result of a fusion between O.V.E.R.K.I.L.L and JUST404 that resulted after a fight. This information is completely false. It is program to do the will of Debug Frisk, Debug Chara with the belief that it is acting within its own free will. Omni404 is nothing more but a tool, gathering information for a mysterious being known as "The Game Developer" to eventually make a return to existence. Its namesake is due to him having code from every other Error and Virus-like character in the omniverse." So I guess that 4 sans thing came from Omni 404 having code from all of them.

[@respicioninofranco9847]

Will there be part 2?

[@tbnrspaceranger]

You (if you want) should make a vid absolutely demolishing other fiction. Like Undertale AUs Vs anime/comics etc cuz I have seen people absolutely shitting on AUs. A dude even said that Naruto negs all of Alphatale. So we don't let that slide do we?

[@narrativeless404]

I can understand Sans AUs are cringe asf This Fandom is literally one of the worst in existence Maybe instead of attacking, you should stop glazing Sans?

[@narrativeless404]

Although I'd appreciate if Canon Undertale was fairly rated, and not just dismissed as something weak But again, glazers literally fight over Saitama vs Goku, and both call the opposite "weak" in a way, so that's just how it is They don't know much about Undertale besides the Sans music everywhere and cringe AUs of him especially when someone just randomly brings up Error 404 in a conversation

Out of all of them, I definitely had some favorites! My top five were probably (not really in order of most to least favorite, just my favorites in general): 1. Vantablack (I didn't know this was a thing and it looks sick) 3:10 2. Gaster!Flowey (I'm just a cringe Flowey superfan) 4:14 3. Kino!Sans (THIS IS REAL? HOLY SHIT THAT'S SICK AS HELL) 8:50 4. Follower!Sans (Probably the best original character I've seen in a long time design-wise) 10:36 5. Eiron (Similar to Vantablack) 11:20 Verse!Sans (11:40) almost made it, so I'll give him an honorable mention. He'd be in the top 5 if I wasn't so unnecessarily obsessed with the awesomeness of Gaster!Flowey 😅

SCP kinda demolishes most Sans AUs anyway 😂 Outcodes fight back and get destroyed, then Error 404 goes on just to get destroyed by the Scarlet King Then goes Fanon and TrueGodverse, matching 3812 but still destroyed for the most part Then goes STS/The Figure and wins all minus the writers who can't do shit to him anyway (That's if we only take Sans AUs, because otherwise this ends way earlier)
