In a world of armored billionaires, super soldiers, and thunder gods, one unlikely hero has proven time and again that you don’t need flashy powers to save the day. Meet Squirrel Girl—a girl with the heart of a hero, the tail of a squirrel, and a track record that leaves even the Avengers in awe. From her humble beginnings to her legendary victories, this is the origin story of Squirrel Girl, the most underestimated—and unbeatable—hero in Marvel Comics.
First Appearance: Where It All Began
Squirrel Girl made her debut in Marvel Super-Heroes Vol. 2 #8 (also known as Marvel Super-Heroes Winter Special) in 1991. Created by writer Will Murray and legendary artist Steve Ditko (co-creator of Spider-Man and Doctor Strange), she was designed to be a lighthearted, tongue-in-cheek addition to Marvel’s superhero lineup.
Murray reportedly wanted to create a character who embodied fun, innocence, and a deep love of comics—a stark contrast to the increasingly dark and serious tone many superheroes were taking at the time. He also wanted to poke fun at the idea that superpowers had to be flashy or cosmic to be effective. Thus, a teenage girl with squirrel-like abilities and a love for nature was born.
In her first appearance, she tries to convince Iron Man to take her on as a sidekick. While he declines, she ends up saving him from none other than Doctor Doom—with the help of an army of squirrels. That’s right—her debut issue features her defeating one of Marvel’s most dangerous villains.
That set the tone for everything Squirrel Girl would become: underestimated, underestimated again, and then victorious against all odds.
How Did Squirrel Girl Get Her Powers?
Doreen Green’s powers come from a subtle mutation—she’s a mutant in some early comics, though later interpretations have avoided classifying her too definitively, likely to steer clear of complex X-Men licensing issues.
Here’s a rundown of her abilities:
- Prehensile squirrel tail: Roughly three feet long and extremely expressive.
- Enhanced agility and strength: She can leap great distances and climb like, well, a squirrel.
- Sharp claws: Perfect for scaling surfaces and digging through obstacles.
- Rodent communication: Her most iconic power—she can communicate with and command squirrels, including her loyal sidekick Tippy-Toe.
- Superhuman reflexes and durability: While not invincible, she’s far tougher than she looks.
- “Unbeatable” aura: While not an official power, Squirrel Girl has developed a tongue-in-cheek reputation for defeating enemies no one else could touch.
It’s not just about the powers, though. What truly makes Doreen special is her attitude. She’s upbeat, kind-hearted, and never backs down from a challenge, no matter how absurd it may seem.
What Makes Her Different From Other Heroes?
Let’s be real—Squirrel Girl doesn’t look or act like your typical Marvel superhero. She wears a squirrel-themed costume, talks to rodents, and seems to approach life like it’s one big adventure. But don’t let the quirkiness fool you—Squirrel Girl’s strength lies in her unconventional approach to heroism.
Here’s what sets her apart:
1. She Defeats Villains Through Empathy (And Strategy)
Doreen doesn’t always rely on brute strength. In many battles, she talks villains out of their evil schemes, offers friendship, or simply outsmarts them. Her solution-oriented mindset often leads to non-violent resolutions.
2. She Breaks the Fourth Wall
In her later solo series, Squirrel Girl often speaks directly to the readers in footnotes and dialogue, adding meta-commentary that makes her comics uniquely entertaining.
3. She Embraces Her Weirdness
Unlike some superheroes who struggle with their identity, Doreen loves being Squirrel Girl. She doesn’t hide her powers or try to be “normal”—she leans into her quirks with full confidence.
4. She’s Actually Unbeatable
Her comic series is titled The Unbeatable Squirrel Girl—and that’s not just for laughs. Over the years, she’s defeated Doctor Doom, Thanos, MODOK, Galactus, and more. Yes, she beat Thanos—and no, it wasn’t a fluke. Even Uatu the Watcher confirmed it.
Major Enemies and Memorable Battles
Though she has a cheerful persona, Squirrel Girl has faced some of Marvel’s biggest bads. Here are a few notable showdowns:
● Doctor Doom
Her very first enemy, and perhaps her most iconic. In her debut, she defeats him with squirrels. It set the tone for her underdog charm.
● Thanos
Yes, THE Thanos. In GLX-Mas Special (2005), she takes him down single-handedly. Many fans were skeptical, but the comic makes it clear: this was the real Thanos, not a clone or robot.
● Galactus
In The Unbeatable Squirrel Girl Vol. 1 #4, Doreen doesn’t fight Galactus—she befriends him. By showing him another planet to eat that doesn’t have intelligent life, she convinces him to leave Earth alone. Problem solved.
● Ratatoskr
A villain drawn from Norse mythology, Ratatoskr is a giant, evil squirrel with godlike powers. In her solo run, Squirrel Girl and her friends must stop this chaotic threat with humor, wits, and heart.
Major Comic Runs and Squirrel Girl Evolution
Squirrel Girl really came into her own in the 2015 solo series The Unbeatable Squirrel Girl by Ryan North and Erica Henderson. This run lasted 58 issues and helped redefine her for a new generation.
Here’s a quick timeline of her most important appearances:
● Marvel Super-Heroes Vol. 2 #8 (1991)
Her first appearance and the battle against Doctor Doom.
● GLA (Great Lakes Avengers, 2005)
She joins the Great Lakes Avengers, a group of oddball heroes. It’s here she starts building her “unbeatable” reputation.
● The Unbeatable Squirrel Girl (2015–2019)
This series fleshes out her personality, her college life as a computer science student, her friendships, and her amazing win streak. It blends humor, heart, and action in a way that made it a fan favorite.
● Squirrel Girl Beats Up the Marvel Universe (2016)
A hilarious graphic novel where she fights an evil clone of herself—and wins, of course.
