The Unbeatable Squirrel Girl #4

Squirrel Girl faces down an absolutely massive, writhing swarm of squirrels — and buried somewhere in that furry avalanche is none other than Doctor Doom, his green armor and iron mask just barely visible as he's engulfed by the horde. Erica Henderson's cover perfectly captures the series' delightful absurdity: Doreen reaches out toward the chaotic squirrel pile with cheerful confidence, her signature bushy tail fanned out behind her. Named one of Slate's Best Pop Culture Characters of 2015, this Marvel series from Ryan North and Henderson continues to make the case that the most fun book on the stands involves a lot of nuts and zero chill.
