The Unbeatable Squirrel Girl #13

Squirrel Girl means business in this 2016 Marvel gem from Ryan North and Erica Henderson — the cover says it all: our hero holds Tippy-Toe aloft with a look of pure exasperation, while a tiny Ant-Man appears in a speech bubble nearby, hinting at an unlikely three-way alliance. "When Ant-Man and Tippy-Toe and Squirrel Girl join forces, someone's gonna get bit!" promises the cover copy, and with Rico Renzi's clean, expressive colors bringing Henderson's art to life, this issue radiates the warm, witty charm that makes this series so hard to resist.
