Ok so based on everything I've researched via Forums and stuff like that, I've come to the conclusion that the Characters from Undertale are probably better suited in a Superhero Universe, and I figured I'd run with it and see how people thought they'd function in an actually Superhero battle and what better opponents then the avengers (Marvel Cinematic Universe version)

so here are the matches

Sans Vs. Iron man

Undyne vs Captain America

Papyrus vs Ant Man

Toriel Vs. Scarlet Witch

Alphys vs. Hulk (Probably be more of a Hulkbuster vs Hulk considering she'd Probably use some kind of giant robot) *I know this is a bad matchup if anyone has a better matchup please let me know.

Mettaton Vs. Black Widow

Asgore Vs. Thor

(I thought about doing Asriel Dreemurr Vs. Thanos, but Asriel can only happen via outside help, plus we don't know how powerful Thanos is and if I were to Bring up the Six Human Souls, I'd have to bring up the infinity gauntlet which much like Thanos, we don't know what it's capable of yet)

Frisk/Chara Vs. Spider-man (you can debate both as separate chrecters if you feel like there would be a whole lot of difference)

Prep Time: Both sides get just bare bones amount of prep time like they maybe have a vague idea of what they are dealing with but not really enough to prep for strengths and weakness: Example. Alphys would know Hulk is a big guy and therefore she needs something big to fight with him, but that's about it. Likewise Iron Man might Know about sans Gaster Blasters, but hasn't really had time to analyze them or know that Sans can go down in one hit.

Stats: With the exception of the Alphys vs. Hulk (For the sake of fairness) I prefer to stick with canon (as in game feats not necessarily those to one of the games timelines so Genocide Sans and Undyne the Undying are allowed if worth noting) and MAYBE some Fandom stuff that is WIDELY ACCEPTED (Not Just a random feat found in a fanfic. In other words, no Super buff fan theory things such as ErrorSans or Ultra-Sans. In fact let's just assume the Six Human souls won't even play a part. You are free to Note things such as Genocide Sans or Undyne The Undying.

Battle Stage: Times Square

Victory Conditions: Won by Death or knock out.

Feel free to comment also if you have other or better Undertale vs. Marvel match ups, put them down below.

if fight place is not marvel universe asriel can solos.( ı dont sure scarlet witch she has reality manipulation????)

I feel like Undertale's feats are too vague to be used on battle forum. Not sure.

@lan_fan: Yeah they are. If we go by game feats then Frisk is around mach 300 (they can dodge lightning) and Sans can dodge their attacks so in reality all of MCU gets horribly speedblitzed here. I think Final Form Asriel is like planet level as well might be wrong, at least continental as he absorbed the souls of everything in the underground and could erase time.

High tier Undertale characters like Sans and Undyne the Undying are street level at best. Omega Flowey probably multiple city block and Asriel is a reality warper so he solos here.

Round 1: Sans speedblitzes here, Iron Man can't tag him.

Round 2. Uh... I think Undyne has the speed advantage and strength advantage here, I don't remember Captain America being strong enough to lift a boulder (which is Undynes only real feat.)

Round 3. Papyrus is said to be Sans level but are these fights incharacter? Papyrus gets stomped here if so, bloodlusted he stomps.

round 4. Yeah Scarlet Witch takes this one. Toriels feats are too vague and not on the scale of Witch.

Round 5. Hulk Alphys has 0 feats.

Round 6. Mettaton, Black Widow is peak human at best. Mettaton can oneshot with bombs and flame.

Round 7. Uh.... probably Thor? Again, Asgore is featless.

Round 8. Thanos murders the verse with IG, Asriel takes it without.
