In her first appearance, she defeated Doctor Doom. Since then, she’s taken on Wolverine, Deadpool, and freaking Thanos—and she’s never lost. Not a bad track record for a superhero–especially considering that the superhero in question is Squirrel Girl, a Marvel Comics back-bencher who’s probably best known for being Luke Cage’s nanny. (She was also on the Great Lakes Avengers, one of the goofiest superteams in history. Like, the Great Lakes Avengers make the West Coast Avengers look like the Dark Avengers.) But now, at long last, Squirrel Girl is getting her own solo ongoing series starting in January.
