the hardest melons require the strongest rules

Kirby is the stuff of Thanos' nightmares.
- Can you hook me up with a nude of this?
  
  Humanity has peaked. Thanks to you. This is the greatest achievement of our species. The magnum opus. The proof that humanity is god incarnate.
- Kirby would just inhale him tbh

Steve. What can't he do
- If his smash adaptation is anything to go by, Thanos will be begging for mercy as he gets 0 to death'.
  
  And then Steve does Up+B in the wrong direction and sails off the stage.

Kratos. Thanos had god-like powers, Kratos killed actual gods including the fates themselves.
- Kratos is my go-to any time a question like this comes up.

Mario. Have fun living when he smashes you with his ass at half the speed of light.
Prince of All Cosmos. Thanos is no where near the largest thing that's been in a Katamari.
- Fan theory: The King of all Cosmos is really just the cafeteria manager for the Celestials and Katamari are just little appetizers for Galactus.

This character canonically has a thanos-killing, anti-stones launcher, it has been confirmed by the dev.
When? Now, since im the dev and i can do anything i want with the lore of my games
- I get the feeling you aren't Prof. Mateas.

I mean, Thanos isn't even that tough. Most of the people fighting him were just human+ power level (notice how they specifically de-powered the Hulk for that fight?). A lot of characters could take him relatively easily.
Somebody mentioned Kerrigan. Yup. Zeratul would 'Nothing Personnel, Kid' the purple guy. Talandar (formerly Fenix) could fuck him up in a straight fight - the dude has died twice, he ain’t afraid of shit. All of the Zerg charcters, probably.
The Doomslayer, obv.
An entire collection of characters from Diablo. Good old Tyrael would bust him open, but any of the angel or demon characters could do that.
Kinda want to put him in a room with Jack of Blades. Nothing kills a supervillan like another supervillan.
- I'ma show my age and say 90s Duke Nukem. Thanos wouldn't stand a chance against bad 80s action-movie parody camp.
- Speaking of those Blizz characters, a number of Warcraft villains could easily take on Thanos too: Archimonde, Sargeras, Deathwing, Lich King.
- Until it is done
- I think the idea with Thanos vs Hulk is that their strength gap wasn't as far apart (presumably Hulk is stronger) but Thanos was using actual fighting and boxing techniques, whereas hulk usually just smashes. Like how a skinny martial artist can take on someone much stronger than them, technique makes a huge difference.
  That said I felt really robbed we never got a BannerHulk rematch with Thanos. Him being intelligent would've let him actually train his technique over the timeskip and complete the character arc.

King of all cosmos from Katamari Damacy
- He'll just make his poor son or his relatives do it. And then will say they didn't do well enough no matter what.

V1 ultrakill would have Thanos shitting and pissing himself
- PURPLEKILL
  
  why kill half the universe for "balance" when you can kill 100% of it for blood!

Dragonborn with level 100 pickpocket, 100 stealth, and alchemy-exploit damage boosts.
- The Nerevarine can pull that much sooner and much easier with infinitely high attributes. Create a custom spell:
  Target self, 1 sec
  Soul trap
  Fortify attribute (Luck)
  500 luck makes you invincible and every skill work 100% of the time.
  
  Much better. Gets us out of the "if Batman had enough prep time" bikeshed.

Any JRPG charter from disk 3 or 4.

The Prince of All Cosmos.
Roll that purple bitch up into a star.
- This katamari feels bitchy. Not that we know what bitchy means

Bayonetta

Literally every single JRPG protagonist.

MELONS
- :(

Does Fromsoft speed runner count? Apparently, you kill gods using slow, deliberate strikes to their feet.

Who dis guy? zoom zoom noises

abs love I was going for Façade-posting but I actually accidentally created a honey trap for nerds (not derogatory, this time)
- I wanted:
  Grace: Trip, you said you were going to put that away.
  phone rings
  thanos: hard melon require throbbing will
  :0
  :[
  Trip: Okay, thanos you need to leave now
  I got:
  The buff senator from metal gear rising could beat thano, but only when red sun is playing

Asura. Asura's Wrath wasn't the greatest game, but it was memorable, and I'm pretty sure this scene makes Asura a contender for pretty much any match up.
- Here is an alternative Piped link(s):
  this scene
  Piped is a privacy-respecting open-source alternative frontend to YouTube.
  I'm open-source; check me out at GitHub.

Pretty sure Kerrigan, the Queen of Blades, could have sent him packing

Doomguy? Thanos snaps, Doomguy dies, goes to hell, fights his way back to Earth and kills Thanos anyway.
Possibly Sierra117, who's power is either luck, or quantum immortality. Thanos can snap all he wants, it wouldn't affect John.

Gordon Freeman, if the Suit Guy ever lets him out again.

DETERMINATION

Solid Snake 🐍

Kain from Legacy of Kain.

Miles 'Tails' Prower

2B and A2 from Nier Automata should be able to do the job.

Just about any could.
The powerlevel hierarchy goes:
Book character < live action character < video game character < anime character < superhero comic character < cartoon character

WoL enters the chat

Gordon Freeman doesnt fuck around
- Crowbar go bonk.
  But wait Thanos is a titan, his HP bar must be huge.
  BONK. FASTER!

Havent seen him yet, but doomguy would absolutely fuck thanos up. Mans killed one of the strongest beings in hell barehanded and stopped the demonic invasion of earth in a matter of weeks.
