She's not a big name, but Squirrel Girl has defeated many of the most powerful Marvel characters. And why not? She has the powers of a squirrel and a girl! She has a knack for taking out some of the most powerful villains in the Marvel Universe. Time travelers, dark sorcerers, mutants, and beings of pure energy arise to challenge both heroes and villains, alike, and only one hero has risen to the occasion every single time. That's right, when Squirrel Girl battles a villain, she always wins.
A young squirrel/lady mutant with the ability to communicate with rodents, Squirrel Girl first appeared among the Great Lakes Avengers and now has her own run of comics. Her list of victories is more than impressive - it's practically unreal. She's taken down the likes of Deadpool, Doctor Doom, Kraven the Hunter, and even Thanos, Destroyer of Worlds.
While the spunky, positive Doreen Green doesn't always succeed in hiding her tail, she always aims to resolve conflicts with minimal violence in The Unbeatable Squirrel Girl. That's even more impressive considering all the Squirrel Girl battles that cement her status as one of the toughest nuts to crack in the history of Marvel. So before she beats up the entire Marvel Universe, let's look at some of the most powerful characters Squirrel Girl has beaten thus far.
Squirrel Girl is separated from her teammates in Great Lakes Avengers Special #1, and during her time away she defeats the mighty Thanos - completely off-panel. Her teammates return to find she's beaten one of the most powerful villains ever. How? Only Uatu the Watcher knows.
He praises the strength and fighting ability of Squirrel Girl, assuring her that she defeated the real Thanos and not some imposter.
Squirrel Girl was obviously a joke from the start, but she proved her might and power by taking out Doctor Doom during her debut in 1991's Marvel Super Heroes Vol. 2 #8. After Iron Man snubs her when she asks for a spot on the Avengers, Squirrel Girl and her squirrel allies take down the powerful Doctor Doom.
While this impresses Iron Man, he tells the then-teenaged Squirrel Girl she's too young to join. Probably a smart move considering what eventually happens to so many of the other teen sidekicks in the Marvel world. Either that, or Stark knew he'd actually end up being the sidekick.
Never bet against Wolverine in a fight. He has one of the most impressive win-loss records of any hero in any universe. Well, except for Squirrel Girl.
In New Avengers Vol. 2 #1, Wolverine and Squirrel Girl brawl it out in front of the other Avengers. Why? She wants to work for Luke Cage and Jessica Jones (as their nanny) and needs to prove her might. Wolverine's years of primal rage, martial arts know-how, and healing ability can only take him so far. He falls at the hands - or is it paws - of Squirrel Girl.
Squirrel Girl and Deadpool have a few things in common: they frequently irk the Avengers and aren't very good at losing. They both also have a lot more power than their quirky personalities let on. One of the most epic Squirrel Girl battles occurs when the two meet.
In Cable & Deadpool #30, the Merc with a Mouth is no match for the Unbeatable Squirrel Girl, and she scratches her way to victory. Keep in mind, Deadpool has years of weapons training, martial arts skill, and a mutant healing ability. He still lost. Never underestimate a woman with the powers of a squirrel and a girl.
