squirrel girl is canonically more powerful than thanos
if anyone is wondering “how the fuck?”: this was a pretty complicated thing that marvel set up, where they evaluated each hero and villain’s capabilities based on who they defeated, how they defeated them, who they were defeated by, and so on.
except, as it turns out, squirrel girl has defeated a LOT of powerful villains. case in point, her very first appearance has her solo-defeating doctor doom, without the help of iron man (who was nearby). this was also one of the few occasions where doom was defeated and it WASN’T a doombot. this turned squirrel girl into kind of a meme once the story hit the internet for obvious reasons, even though this story was just a one-shot. so then marvel brings her back, and has her defeat three villains in one comic, INCLUDING THANOS. (they even had other characters confirm that it wasn’t a trick, it wasn’t a fake thanos, that was actually thanos and he lost to squirrel girl because she set squirrels on him.)
the result? squirrel girl always wins. if there is an argument about “who would win?”, and squirrel girl is one of the options, then she wins by default because she’s squirrel girl. and this means that squirrel girl has to be the most powerful character in marvel by raw stats, because she always wins. you genuinely can’t beat squirrel girl.
by the by: she’s coming to the mcu soon in the new warriors tv show. that should be entertaining.
