2. Squirrel Girl

LOL…haha…No, but for real.

Every comic book universe has its constants. The Infinity Gems have specific powers. Wolverine's healing powers ability works in a certain way. And no one can beat Squirrel Girl. That's her entire shtick. Whenever she's pitted against an opponent, the universe bends and turns that opponent into the silliest version possible, which is invariably the one that can be defeated.

Once a murder machine, MODOK transforms into a round man with little arms. Science wizard Dr. Doom becomes an egotist who loves to talk in the third person. And let's be honest; Batman has the capacity to be extremely silly.

No, Squirrel Girl couldn't beat Grim Avenger of the Night Batman, but she wouldn’t fight him. She'd fight Takes Himself too Seriously and is Always Sad Batman. She'd basically be fighting Lego Batman. And she'd kick his ass.
