Powers/Abilities: Ratatoskr is an immortal deity based in Asgard, who was tasked with running messages between the dragon Nidhogg and the eagle at the roots and branches of Yggdrasil. Often in the form of a standard squirrel, Ratatoskr grew to love spreading chaos and lies, and delved into anarchy with thoughts of destruction. A powerful shapeshifter, Ratatoskr's true form seems to be a cartoonish giant black squirrel with a horn, but she has adopted the forms of Girl Squirrel (a heroic squirrel), a whale, and, more recently, the form of reporter Rachel Oskar. Ratatoskr can influence and control minds by whispering in the ears of others. Ratatoskr naturally possesses superhuman strength, agility, and durability.

(Norse/German Myth/Thor II#83 (fb) - BTS) - "Since the beginning of time, Rattatoskr ran messages between the dragon Nidhogg, who feeds on the roots of the tree, Yggdrasil, and the eagle that lives above and feeds on branches and leaves."

(Unbeatable Squirrel Girl I#7 (fb) - BTS) - Ratatoskr plagued Asgard for many centuries, and was frequently jailed for her habit of whispering chaos into the ears of others and causing them to fight. In time, after escaping imprisonment, she manipulated the Wabanaki people, who called her Meeko, and she nearly destroyed all civilization, but the Asgardians stopped her, confined her to squirrel size, and imprisoned her for eternity.

(Thor II#83 (fb) ) - As boys, Loki and Thor would sit in the branches of Yggdrasil and listen to Ratatoskr's tales. Ratatoskr once warned Eitri the dwarf of Loki's plans for the Mjolnir mold, and the warning lea to Eitri's death over time.

(Unbeatable Squirrel Girl I#8 (fb) - BTS) - Centuries ago, Loki weakened the barriers of Ratatoskr's prison in a long-term plot, eventually allowing Ratatoskr to escape.

(Thor: Blood Oath#2) - Thor and the Warriors Three climbed Yggdrasil, where Ratatoskr offered them stories in exchange for seeds from the immortal apples of Idunn. Ratatoskr told them of the eagle and the dragon.

(Thor II#83) - Thor found the corpse of Ratatoskr during the Asgardian Ragnarok.

(Unbeatable Squirrel Girl I#7 (fb) - BTS) - After being back in prison for a time, Ratatoskr escaped again, and returned to Earth to sow seeds of chaos. She chose to pose as Girl Squirrel, a small heroic squirrel, to manipulate public opinions against the heroine Squirrel Girl.

(Unbeatable Squirrel Girl I#6) - When lions escaped their enclosure at the zoo, Girl Squirrel defeated the beasts and returned them to their cages. The media wrote stories on Girl Squirrel, even making T-shirts for her. That night, Ratatoskr broke into apartments around the city, whispering dark messages in the ears of civilians, including Spider-Man and Thing. When she broke into Squirrel Girl's home, Mew the cat scared her away. The city outside descended into chaos as people followed Ratatoskr's suggestions.

(Unbeatable Squirrel Girl I#7 (fb) - BTS) - As chaos spread over Earth, Ratatoskr turned many civilians against each other, inciting violence and fury between them. She even turned the Avengers (Falcon, Black Widow, Captain America, Hawkeye, Spider-Man) against each other.

(Unbeatable Squirrel Girl I#7) - Squirrel Girl, Chipmunk Hunk, and Koi Boi soon sought out Ratatoskr directly, getting the villain to reveal her true form, instead of her disguise as Girl Squirrel. Ratatoskr tried getting the heroes to accept that she could burn the world down to build a better one, but they refused to listen, and Ratatoskr then attacked directly.

(Unbeatable Squirrel Girl I#8) - Ratatoskr fought the three heroes until she used her mind influencing powers to turn Chipmunk Hunk and Koi Boi against Squirrel Girl. Squirrel Girl put on web-shooters and briefly managed to trap Ratatoskr in webbing, but a mind-controlled crowd freed the villain. Ratatoskr had Squirrel Girl pinned and was ready to influence her mind when Thor (Odinson), Thor (Jane Foster), Loki (with a Cat Thor head), Nancy Whitehead, and Tippy-Toe all arrived from Asgard, wearing ear plugs to block Ratatoskr's powers. Squirrel Girl was freed, then Thor (Jane Foster) hit Ratatoskr with Mjolnir. Soon, Ratatoskr's powers were divided, and Loki returned her to her imprisonment in Asgard, through the Bifrost.

(Unbeatable Squirrel Girl II#20) - After Squirrel Girl's foe, Melissa Morbeck, was arrested, Ratatoskr (having escaped her cell briefly) posed as a human lawyer to see Morbeck, then he revealed his true identity.

(Unbeatable Squirrel Girl II#44 (fb) ) - In Asgard, Ratatoskr was left alone in her cell when Mangog attacked. Ratatoskr escaped to see Thor (Jane Foster) battling the Asgardians, and learned Mangog was working with Malekith, who had designs to attack Earth. Visiting Alfheim, Ratatoskr saw that the Light Elves were being conquered by the Dark Elves, and she realized she needed to work against Malekith to sow chaos. Abandoning her plans to work with Morbeck, Ratatoskr instead decided to bring Squirrel Girl to Canada with her to overthrow the North American invasion of the Frost Giants.

(Unbeatable Squirrel Girl II#43 (fb) - BTS) - Ratatoskr forcibly teleported Squirrel Girl from the Negative Zone to New York City, where she assumed Loki would send her on to Canada.

(Unbeatable Squirrel Girl II#43) - In northern Canada, Squirrel Girl was sparring with Gary and Danielle the Frost Giants when Ratatoskr revealed herself.

(Unbeatable Squirrel Girl II#44) - Ratatoskr explained her recent history to Squirrel Girl while they battled Danielle and Gary. Squirrel Girl agreed to work with Ratatoskr if she promised not to kill, betray her, or mind-control others. Ratatoskr changed herself into a human form and took the name Rachel Oskar, then Squirrel Girl chose the alias Scarlett Q. Goryle for herself. They went to a local pub to make inquiries of the civilians, including Jack, but Rachel caused a fight to break out.

(Unbeatable Squirrel Girl II#45) - Squirrel Girl broke her alliance with Ratatoskr when she realized the goddess only wanted to sow chaos and saw the world as doomed. Ratatoskr went off on her own, mind-controlling Frost Giants, including Daisy, into serving her. In time, she forced Daisy to dance and sing before her, then she realized she wanted to be different and had Daisy carry her across the wilderness to Squirrel Girl. She agreed to team up with Ratatoskr again, and she had Daisy hit them with a bat to propel them through the air to the Frost Giant stronghold in Churchill.

(Unbeatable Squirrel Girl II#46) - Squirrel Girl suggested they interrupt the Frost Giant food supply line of beluga whales, so Ratatoskr changed into a whale form and communicated with the whales. Ratatoskr led the whales in an attack on the Frost Giants, including Patrick, and helped Squirrel Girl take down their whaling ships. Embracing the idea of sowing chaos for positive change, Ratatoskr then suggested they educate the Frost Giants on liberation, turning them against their king in an attempt at revolution. Back in New York, Ratatoskr and Squirrel Girl bragged to Koi Boi, Chipmunk Hunk, Brain Drain, Tippy-Toe, Nancy Whitehead, and Mary Mahajan that they had liberated North America. Loki arrived to put Ratatoskr back in prison, but Squirrel Girl and Nancy Whitehead vouched for Ratatoskr. Later, Rachel Oskar became an investigative reporter in Canada, exposing corrupt politicians like Wilson Brunstad.

(Unbeatable Squirrel Girl II#49) - When Squirrel Girl was overwhelmed facing many of her enemies at once, many of her allies showed up all at once to aid her, including Ratatoskr, the giant Tree Lobster, Kraven the Hunter, Rhino, Ms. Chloe, Sentinel X-42903-22, G'illian Blax'zthor, Hippo, Sootori, the Chrrt-Chuk race, Chef Bear, Alfredo the chicken, and Mole Man.

(Unbeatable Squirrel Girl II#50) - Galactus showed up to de-escalate the conflict and then sent all the operatives home, including Ratatoskr.

(Thor VI#11 (fb) - BTS) - Hearing Thor had ascended to the throne, Ratatoskr returned to Asgard and began having fun spreading chaos.

(Thor VI#11) - Finding Asgard empty, Ratatoskr located Thor in a mysterious Odin-created village, and told him how empty Asgard was.

(Thor VI#12 (fb) - BTS) - Ratatoskr whispered to Throg about the existence of Donald Blake, who was killing Thors.
