When it comes to heroes who have defeated both Thanos the Mad Titan and Galactus, the Devourer of Worlds, there isn't a particularly long list. However, one unlikely character has sparred with both cosmic villains and come out on top: Squirrel Girl.

Doreen Green first appeared in Marvel Super-Heroes #8 (1991) and was created by Will Murray and Steve Ditko. Doreen has enhanced strength and agility, a big bushy tail, and the ability to communicate with squirrels. She might be best known as a member of the Great Lake Avengers, however, the character was brought back to the forefront in Ryan North and Erica Henderson's Eisner Award-winning The Unbeatable Squirrel Girl. In the series, she went face-to-face with some of Marvel's biggest villains and came out on top.

In The Unbeatable Squirrel Girl #3 (2015), Doreen finds herself on the moon in an effort to stop Galactus. She uses Iron Man's armor to get into space and when she arrives, she politely asks him to have a chat. Squirrel Girl tries her best to kick and punch the giant cosmic being's foot to no avail. However, when Squirrel Girl inquires about his plans for Earth, the topic of Thanos comes up and the two bond over their hatred over the "fool." She manages to convince Galactus to feast on a planet rich with nuts instead of Earth. The two end up going back to the moon after over-eating on nuts. Galactus agrees to spare Earth.

So, how did Squirrel Girl defeat Thanos? In the 2005 Great Laker Avengers holiday special Glx-Mas (2006) by Dan Slott and Ty Templeton, Squirrel Girl is on a mission to get more toilet paper for the team. However, she notices a spaceship in a field and when she investigates, she runs into Thanos. While the fight isn't shown, Squirrel Girl stands over Thanos' body as Uatu the Watcher shows up to tell her she just saved the multiverse. The Watcher even states its the real Thanos. There isn't much explanation given, but Doreen beat Thanos on a one-on-one battle.

Squirrel Girl might not seem like the most intimidating threat in the Marvel Universe. But, with her trusted squirrel Tippy-Toe by her side, she's managed to convince Galactus not to feed on Earth (and subdued him with nuts) and stopped Thanos before he tried to destroy the multiverse. The stories the defeats happen in might be silly, but they prove that even against the biggest threats in the galaxy, Squirrel Girl still kicks butts and eats nuts.
