With her unique combination of wit, empathy and squirrel powers, computer science student Doreen Green is all that stands between the Earth and total destruction! Well, Doreen plus her friends Tippy-Toe (a squirrel) and Nancy (a regular human). So mainly Squirrel Girl. Then, what hope does Earth have if Doreen gets hurled back in time and erased from history? Some hope, hopefully, as Howard the Duck is waiting impatiently for a crossover! And if one animal encounter isn't enough, prepare for Swarm, a buzzkill made of bees, and Mole Man, the subterranean super villain looking for love! But you're not here for flowers and kissing, you're all about computer science and super-heroics.Get both - and more - in a showdown with Count Nefaria! You go, Squirrel Girl!

Squirrel Girl takes Nancy to visit her mom in Canada! What could possibly go wrong? How about the return of a villain not seen for more than a decade? One that prompts the inter-species team-up you've been waiting for: squirrels and ants! And also Squirrel Girl and Ant-Man. Then, when Taskmaster strikes, who will stand between him and total domination? You probably guessed Doreen Green—but it's actually Nancy's cat, Mew! Squirrel Girl's co-creator Will Murray returns for a special story—and he's bringing the Hulk! And Doreen gets a new Flying Squirrel suit from a mystery benefactor, but is there more to this gift than meets the eye? Plus: When Squirrel Girl goes to the Negative Zone, it's up to Koi Boi, Chipmunk Hunk and Brain Drain to keep the city safe. Uh-oh! Collects The Unbeatable Squirrel Girl (2015B) 12-21.
