For a long time, Squirrel Girl was kind of a joke—a failed concept for a superhero writers occasionally referenced to poke fun at the idea of dumb comics gimmicks. Her real name is Doreen Green, and she's a mutant born with the prehensile tail of a squirrel, and with some squirrel powers to boot. She can talk to squirrels. She's as agile as a squirrel. She…really likes nuts? See? Not much to her. In spite of the character's shortcomings, over the years she gained the title of "unbeatable" after defeating the likes of Wolverine, Thanos, and Deadpool.
Embracing the gimmicks and the title, writer Ryan North took the reins for Doreen's first solo series, The Unbeatable Squirrel Girl—and the results are equal parts charming and funny, and quirky without forced affectations. Her adventures are frequently hysterical, and often double as spot-on parodies of comic book tropes that are, themselves, fully functioning comic book stories. Take, for instance, her confrontation with the planet-eater Galactus. She whoops him by tricking him into switching to a nut diet (they're high in energy!), but only after a side-splitting, thought-provoking argument over gender-specific pronouns. Or when she gets the X-Men's Jubilee to confess that Wolverine's claws don't actually make the iconic "snikt!" sound (turns out he makes that sound with his mouth). The Unbeatable Squirrel Girl may be a silly idea, but it makes for a thoroughly charming read.
