I didn't know what the @#!*% was going on. But it was an invasion. Right here in America. An invasion! And my first thought -- my first thought was: The baby! I've got to find and protect the baby. And maybe that doesn't surprise you, but it surprised the @#!*% out of me. I will confess this... When I first auditioned to be the nanny, I was really hoping that the Avengers would notice me and say amongst themselves: We really need her on the team. I took this job hoping to be an Avenger but now all I cared about -- all I cared about was protecting the child.

Squirrel Girl (real name Doreen Green), is a fictional character and superheroine in the Marvel Comics Universe, appearing as the main protagonist of The Unbeatable Squirrel Girl, a major character in the G.L.A. comics, and a supporting character in other individual comics.

Her ability to control squirrels is surprisingly effective and has allowed her to defeat major supervillains. She was a member of the Great Lakes Avengers for much of the duration of that group, and later began serving as nanny to Danielle Cage, the daughter of Luke Cage and Jessica Jones.

Her first appearance was in Marvel Super-Heroes vol. 2, #8, a.k.a. Marvel Super-Heroes Winter Special (cover-dated Jan. 1992), in a story plotted and drawn by the late Steve Ditko and scripted by character conceptualizer Will Murray.



Doreen is the daughter of Dorian and Maureen Green, and suffered from an alteration in her genes that granted her squirrel-like abilities, growing a three foot tail. Though the doctor informed her parents she wasn't a mutant, she believed herself to be for a long time.

At an early age, Doreen learned that she could communicate with squirrels, and saved a squirrel from a dog. The squirrel's name was Monkey Joe, and told Doreen that she should help others, inspiring her to become a superhero. In addition, Doreen came up with the title "The Unbeatable Squirrel Girl", and fantasized about becoming a hero.


In her debut, Squirrel Girl took down Doctor Doom without the help of Iron Man, who refused her request to become his new sidekick earlier that day. The two were attacked by Doom, and Squirrel Girl helped Iron Man escape from his grasp, and the two were victorious.

Another hero she helped was the Hulk, who had fallen next to her tree house when fighting the Abomination. Hulk was blinded, and reluctantly asked for Squirrel Girl's help, who had the villain swarmed by squirrels, and helped Hulk land blows. She would later join the Great Lake Avengers after helping them fight off muggers, and witnessed the death of Grasshopper.


Early Life

Doreen Green was born in Los Angeles, California to Dorian and Maureen Green, whom noticed that their daughter had a prehensile tail similar to that of a squirrel. The parents then spoke with the doctor, who told them that she wasn't a mutant, but Doreen believed herself to be one for years. Upon her birth, Doreen's genes were somehow modified with that of a squirrel, which qualifies her as a human-mutate. Growing up in California, Doreen later learned of her ability to communicate with squirrels when she was ten years old. After saving one from a dog chasing him, the squirrel befriended Doreen, adopting the name "Monkey Joe" and encouraged the girl to use her powers for good.

Doreen Green was born in Los Angeles, California to Dorian and Maureen Green, but she was born with DNA being modified with squirrel genes. When her parents spoke with the doctor, who lamented that she wasn't a mutant since she was human-mutate, but Doreen believed herself to be one for years. Born with a prehensile tail, Doreen learned that she could communicate with squirrels when she was just ten years old. When communicating with one, she saved it from a dog and it became one of her closest friends, whom would adopt the name "Monkey Joe". She would then fantasize of becoming a superhero, and gave herself the title of "The Unbeatable Squirrel Girl" after receiving encouragement from Monkey Joe to use her powers for good.

Becoming Squirrel Girl

Due to Monkey Joe's encouragement, Doreen started to fantasize herself becoming a superhero, and adopted the name "The Unbeatable Squirrel Girl". Knowing that she would have to prove herself to other heroes, Doreen would encounter the superhero Iron Man near Stark Industries and ambushed him. Despite her attempts to prove herself and become his sidekick, Iron Man politely declined before being attacked and captured by Doctor Doom. The supervillain would underestimate Squirrel Girl, but she managed to help free Iron Man by tasking squirrels to attack Doctor Doom and bite through is aircraft. Afterward, Iron Man thanked Doreen for her assistance, and the two went their separate ways.

A year later on her fifteenth birthday, Doreen witnessed the Hulk land near her treehouse during his battle against his arch-nemesis, the Abomination. The Hulk was blinded from a concussion, and reluctantly accepted Squirrel Girl's help in fighting the Abomination, which was a success as Green told the Hulk when throw his punches. Later on, Doreen moved to New York to help others and saved the Great Lakes Avengers, who decided to recruit her. During her tenure with the group, she witnessed the death of fellow teammate Grasshopper, and lost Monkey Joe to Leather Boy, who was disguised as Doctor Doom. After stopping Maelstrom from destroying the world, she would adopt a squirrel named Tippy Toe, who would assist her in stopping M.O.D.O.K., Terrax, and Thaons (which Uatu the Watcher confirmed was the real one and not a clone or copy of the Titan).

Squirrel Girl earned a reputation due to stopping great threats, to the point that S.H.I.E.L.D. agent Dum-Dum Dugan offered her position with the agency, but she declined. After speaking with Dum-Dum Dugan, she encountered the Thing battling Bi-Beast, and assisted the hero in stopping the villain by ordering squirrels to place garbage around him. The Great Lakes Avengers would change their name to the Great Lake Champions, and fought against Deadpool until Green stopped him since the mercenary was taken aback by her name. Afterward, Deadpool assisted the team in fighting against A.I.M., and later became a reserve member for the group. Around this time, Doreen developed a crush on the New Warriors member Speedball, who had turned into a darker hero under the name "Penance". She confronted him and tried to convince him to leave his new persona, but she decided to back in time to prevent this by using one of Doctor Doom's time machines. Instead of going into the past, she went into the future where she learned that Speedball returned to his old persona, and asked her to back to her time and kick Deadpool out of their headquarters.

During the Skrull's invasion, Squirrel Girl worked with the Great Lakes Champions to deal with their fellow teammate Grasshopper, who was revealed to be a Skrull infiltrator. Afterward, Doreen realized that she was holding her teammates back since she was competent enough to fight against great threats, and left the group after stopping Fin Fang Foom. Seeking employment, Doreen auditioned to be the nanny of Luke Cage and Jessica Jones' daughter Danielle Cage, and was given the job. While Luke and Jessica dealt with threats, Doreen protected Danielle while living in the New Avengers' mansion. She would leave the profession and enrolled into Empire State University, where she studied computer science. Around her enrollment, Squirrel Girl succeeded in having Kraven the Hunter end his long vendetta against Spider-Man, and found a planet for Galactus to consume.

During her second year at the university, Doreen joined the New Avengers under the leadership of Sunspot, but would also join the U.S.Avengers when they started work with S.H.I.E.L.D. During this time, she would help redeem villains such as Brain Drain and Kraven the Hunter, with the latter helping fight a version of Ultron. In addition, Squirrel Girl worked with other heroes such as Gwenpool, who asked for her assistance in saving her brother from Mephisto's realm. She would then be tasked by the Norse god Loki to prevent the Frost Giants from taking over North America, and was assisted by Ratatoskr to send the race back to Jotunheim.

Powers and Abilities


Despite the silly name, Squirrel Girl is one of the most powerful superheroes in the entire Marvel Universe. Her powers include enhanced strength, speed, reflexes, agility, and leaping ability "proportionate to that of a squirrel". Her teeth are strong enough to gnaw through metal.

She has also small, sharp claws rather than fingernails and retractable knuckle spikes—both principally used for climbing. She can speak with squirrels, who tend to do her bidding because of how well she treats them. Oh, and she has a semi-prehensile squirrel tail.


Doreen is a skilled negotiator, preferring to find a non-violent solution whenever possible. This has allowed her to make friends with previous opponents or enemies and has led some to reform, such as Brain Drain. Others view her as being neutral or at least not acting against their interests or plans. In one instance, she was able to borrow a time machine from Doctor Doom because he reasoned that allowing her the use of the machine would not interfere in his affairs.

She is also an expert at computer science and has taught computer courses at Empire State University. Kamala Khan attended one of her classes. As seen in the Marvel Rising series of comic books, they figured out each other's secret identities through various hints and clues, and became fast friends afterward.



  • In Marvel Rising: Secret Warriors, she was voiced by Milana Vayntrub.


  • In Fantastic Four: World's Greatest Heroes, she was voiced by Rebecca Shoichet, who also voiced Twilight Sparkle (singing voice) in My Little Pony: The Movie, and Sunset Shimmer in My Little Pony: Equestria Girls.
  • In Ultimate Spider-Man, she was voiced by Misty Lee, who also voiced Titania in the Fire Emblem series, Camilla in Fire Emblem Heroes, Polar and Pura in the Crash Bandicoot series, Tawna Bandicoot in Crash Team Racing: Nitro-Fueled, and Big Barda in DC Super Hero Girls.
    • Lee reprised her voice for the character in Lego Marvel's Avengers.

Video Games


  • In Squirrel Girl Goes to College: A Squirrel Girl Play, she was portrayed by Alyssa Buckner.


  • Despite being considered a silly character, she has a great win ratio, having defeated iconic characters such as Thanos, Doctor Doom, The Mandarin, Deadpool, Fin Fang Foom, Black Widow, Sam Wilson, Hawkeye, Spider-Man, Wolverine, Baron Mordo, and more.
    • And to confirm, Uatu the Watcher stated that she defeated the real Thanos, not a clone or copy of him.
    • She has broke the fourth wall similar to Deadpool and Gwenpool, meaning she has some medium awareness.
