Nancy proposed a theory that Girl Squirrel was actually the Asgardian Ratatoskr, looking up a Wikipedia article for information, and they realized the squirrel-god was behind the gossip and rioting. Tippy joined Nancy and the three heroes in going to Avengers Tower, where the Avengers were arguing like everyone else. The Avengers attacked, and Squirrel Girl and her friends defeated them in combat. They sought out the two Thors, and Nancy and Tippy-Toe went with them to Asgard to fix the escaped Ratatoskr's cell, while Squirrel Girl, Chipmunk Hunk, and Koi Boi stayed on Earth to fight Ratatoskr. Nancy immediately asked if they had cats in Asgard.

(Unbeatable Squirrel Girl I#8) – After interacting with Doreen online, Nancy was astounded by Asgard. With Tippy, Nancy saw Thor (Jane Foster) and Thor Odinson interact with Loki, who Nancy convinced to shape-shift into Cat Thor.

Nancy found herself impressed with Maureen, and she loved seeing photos and hearing stories from Doreen's childhood, especially when Doreen grew frustrated. Doreen soon took Maureen and Nancy across the rooftops as Squirrel Girl, returning to the roof of their new apartments. There, they were seemingly attacked by Brian Drain, who had grabbed Mew and Tippy, before they defeated him. Realizing Brain Drain's programming was stuck in the 1940s era, Nancy and Squirrel Girl reprogrammed Brain Drain, using cell phone technology while bringing his components up to date, and after they rebooted him, Brain Drain thanked them for putting him in control of his own destiny again. He then agreed to audit college classes with them, wearing a rudimentary disguise. Later, they visited Avengers Island through the teleporter for lunch, with restaurants like By Odin's Beer, Waffle X Program, Soup thOr Salad, and Great Cakes Avengers.

Dr. Doom then attacked.

(Unbeatable Squirrel Girl II#3) – After interacting with Hulk and Iron Man (who was trying to sell an Iron Manicure) online, Nancy stopped Jubilee and the Punisher from attacking Dr. Doom by convincing her Doom was a cosplayer. Realizing this was a Dr. Doom from the past who'd just been defeated by Squirrel Girl, Nancy manipulated Doom into taking her with him to find Squirrel Girl back in 1962. They landed in the middle of a group of students, all from the present and trapped in the past, including Trish and Mary Mahajan, and Nancy warned SG about this being the Dr. Doom from the past. To demonstrate how the future is impacted by time travel, Doom upgraded Nancy's phone, and she accessed her off-line Wikipedia to confirm that Doom would take over the planet, rechristening it Planet Doom in the future. Doom attacked SG, who saved Nancy from being hit with a laser blast. SG tossed the students all into a pool four blocks away, then followed to regroup.

(Unbeatable Squirrel Girl II#4) – Mary, Nancy, and Squirrel Girl talked about plans to defeat Doom, including stealing his time machine. Nancy suggested they go back in time and teach Doom as a baby to be a better person, but agreed to help Mary Mahajan build EMPs, while Squirrel Girl went after Dr. Doom.

Mole Man retaliated by sinking all of Central Park into Subterranea. Mole Man continued to flirt with Squirrel Girl, but he ordered his Moloids to attack when Nancy slapped him. Mole Man retreated, but later began stealing major buildings to try to force Squirrel Girl to go on one date with him.

(Unbeatable Squirrel Girl II#10) – As Mole Man kept stealing buildings, Nancy went to physics class with Doreen. After hearing about how Squirrel Girl couldn't confront Mole Man due to the media presence in Central Park, Nancy stated that she would confront Mole Man directly. Doreen went with her to Central Park, where she lured away the media, while Nancy jumped in Mole Man's hole to Subterranea. She told Mole Man that Doreen wasn't interested, but he wouldn't hear it, and when Mole Man threatened to kidnap Nancy, she unleashed a bag full of squirrels, including Tippy, against him so she could escape. Nancy reported in to Doreen, who went on to confront the Mole Man. After Mole Man instead chose to love Tricephalous, one of his monsters, Nancy, Mary, Chipmunk Hunk, and Koi Boi all helped Doreen put dirt back under the missing buildings, as squirrels in Iron Man suits lifted the buildings up.

After getting a call from Iron Man, Doreen took Tippy, Nancy, Ken, and Tomas to Stark Tower, where Doreen introduced Nancy briefly as Nautical Nancy, stating that she could talk to boats. Iron Man showed them a machine he had built based on the High Evolutionary's designs, and he wanted squirrels to experiment on but Doreen refused. The High Evolutionary then attacked with henchmen and several New-Men (including Clarence the whale, Sally the ostrich, Claude the electric eel, and Commander Huggy Q. Loveyface the Sixth the polar bear). During the fight, Squirrel Girl was knocked into the HE's machine, and Nancy struggled, working with the Friday A.I., to get her out, but SG emerged with a duplicate of herself, who later named herself Allene. Allene went to campus with Doreen, Nancy, Tippy, Tomas, and Ken, and proposed that they take a more active role in stopping crime by having the squirrels, chipmunks, and fish all watch out for crimes, allowing them to be more proactive in their crime-fighting. The others agreed to give it a try, but on their way home, they discovered that Chompsky the squirrel had been hit by a car. When Allene went off for a few days on her own, Nancy helped Doreen use social media tracking, looking at accounts by Chirp Zudarsky, Squirrel ebooks, and Spider-Man (Miles Morales) to track Allene down. Allene described a comprehensive plan to prioritize squirrel lives and to launch a war on humans to do so. They learned that she had tied up Tony Stark, stolen his armor and his duplication machine, which she was using to make dozens of copies of squirrels who would be loyal to her. Allene was hurt when Nancy, Doreen, and Tippy didn't take her side. Allene attacked Doreen, and the war went back to Tony Stark's home, where they freed him, and they soon realized that Allene had plans to conquer the world to make it better for squirrels. Allene used a trick to lure Doreen and her friends hundreds of miles away from the city. Upon returning to NYC, Doreen and her friends partnered with S.H.I.E.L.D. (Nick Fury II, Phil Coulson, Maria Hill) and watched Allene defeat Hulk, as they realized she had defeated most of the city's heroes and villains and was now using their technology. Allene easily defeated them as she banished S.H.I.E.L.D. to the Negative Zone, then the heroes shed their costumes and fled. Days later, Doreen and her allies joined with Venom ("Flash" Thompson), Hippo, Rocket Raccoon, and Kraven the Hunter, and Doreen ended up with Thor's power, freeing the heroes from the Negative Zone. After the fight was finished, Doreen realized Tippy had broken her back during the rescue, and she liberated the heroes to heal and stabilize her. In the end, they let Allene go to the Negative Zone to populate a planet with her squirrels.

When they arrived, they found a remote cabin with no electricity, and Nancy was thrilled at the chance to knit, read, swim, and hike, though SG was annoyed with no social media. After Maureen told embarrassing stories about SG, she revealed that someone had stolen a muffin, and SG soon discovered a village of two-inch clones of Enigmo living underneath the Earth. The Enigmos formed to full-size and split apart again, soon tying up Nancy, Maureen, and SG.

(Unbeatable Squirrel Girl II#13) – After Tippy-Toe led squirrels into holding off the tiny Enigmos, Doreen got Nancy, Maureen, and Tippy to safety in the nearest town.

After meeting bear butlers Mister Edwin and Mister Bettany, Nancy was determined to question Morbeck, who had hoped to speak to Doreen alone. Nancy caught Morbeck in some lies, revealing she had villainous intentions, so Morbeck had the bears lock them in. Doreen grabbed Nancy and burst through the window to escape, then summoned Tippy-Toe and other squirrels, but Morbeck summoned rats to counter her. Doreen tried flying away with Nancy, but Morbeck caused her suit to malfunction and crash, then promised to let Nancy and the squirrels go if Doreen came inside with her to hear her plans. Nancy immediately called the police, but when they arrived, the place was surrounded by animals from the zoo that Morbeck was controlling.

(Unbeatable Squirrel Girl II#19) – Koi Boi, Chipmunk Hunk, Mary Mahajan, and Nancy Whitehead rushed into Morbeck's home with the police, past mind-controlled zoo animals, and found Squirrel Girl battling armed bears and Melissa Morbeck already gone.

Morbeck had Doombear, a bear in a Dr. Doom costume, reveal itself to SG and her allies, and Morbeck spoke through the bear, revealing she planned to frame Squirrel Girl for the animal and mosquito attacks across the city. Squirrel Girl soon challenged Morbeck to face her directly, and Morbeck did so, speaking over a megaphone and knowing that the media was recording every move. SG, Chipmunk Hunk, and Koi Boi battled the animal army while Mary and Nancy worked on creating an EMP. Tippy shaved off her fur to pose as a rat, then she ran directly up to Morbeck and detonated the EMP, shorting out her ability to control the animals. Morbeck was arrested.

After the long flight to the Savage Land (with Tippy Toe joining them), they stopped at the Savage Brands store, then met Latverian student Stefan Klossner, who Nancy was immediately attracted to. Dr. G soon introduced herself and gathered all the contest winners, taking them into the Savage Land to see dinosaurs. After hours of viewing and interacting with dinosaurs, during which Nancy and Stefan flirted, they were taken to the Core, the computer center of the Savage Land, where Dr. G. told them she needed their help because the Savage Land was dying.

(Unbeatable Squirrel Girl II#23) – Dr. G explained the history of the machines in the Savage Land with members of her staff, including Donnie. She stated that the students needed to come up with a solution to fix the alien machines or the dinosaurs would die. The students, including those from Wakanda, Latveria, and K'un-Lun, began focusing on programming, with Stefan and the Latverian students deciding to just build a Doombot to help them. Though frustrated by Stefan's loyalty to Doom, Nancy remained attracted to Stefan. Stefan soon joined them for lunch at "Savagely Delicious Land O'Food," where Nancy complimented Stefan on his open-mindedness as they discussed the differences in their upbringings and political beliefs. Nancy confided in Doreen how scared she was about the attraction she was feeling to Stefan. Back in the computer lab, Nancy named Stefan's Doombot "Antonio," then they realized that many computer parts were missing. Doreen soon discovered a robot T-Rex in the shadows, revealing itself to be Ultron.

(Unbeatable Squirrel Girl II#24) – After interacting with Squirrel Girl and Tippy online, Nancy hid in the shadows with Stefan, who had activated Antonio the Doombot to help SG and Tippy fight Ultron.

(Unbeatable Squirrel Girl II#27) – After waking, Nancy began her day and interacted with her friends Doreen, Tomas, Ken, and Brain Drain, swiftly realizing they were all pressuring her for intel on Galactus. She soon found Tippy and they realized they were on an alien planet where holograms were trying to pressure them into revealing Galactus' weaknesses. They soon learned they were on the planet Chitt-Crrt among a race of green alien squirrels called the Chrrt-Chuk, when their leader Chtty introduced himself. They learned that aliens posing as the Silver Surfer had convinced the Chrrt-Chuk that Galactus was coming to consume them unless they turned over all of their riches, and the squirrels had panicked and tried teleporting Squirrel Girl to them, getting Nancy and Tippy instead. Not only could they not send Nancy and Tippy home, but they said a bomb left by the "Surfer" was set to go off in mere hours.

(Unbeatable Squirrel Girl II#28) – Nancy and Tippy were trying to deactivate the space bomb when a ship crashed, destroying the bomb and revealing it to be a fake. On the ship were Squirrel Girl, Loki, Drax the Destroyer, and Mew.

When the real Silver Surfer showed up, SG attacked, thinking he was the impostor.

(Unbeatable Squirrel Girl Girl II#30) – After interacting with Squirrel Girl online, Nancy saw the others turn the missiles around, saving them. Nancy and SG challenged the Surfer to explain the Power Cosmic to them, demonstrating how computers could be explained to a woman from the 1800s as an example of how hard concepts could be understood by presumably simple minds, but Surfer refused. Aboard Sootori's alien ship, while SG sought to make peace between the alien races, Tippy and Nancy went looking for the Power Cosmic, and Tippy stole it, using a hologram to make it appear as if she hadn't (as Nancy used an alien bathroom that baffled her). Using the power, Tippy considered getting justice on the grifters as the Silver Squirrel, but decided it was too complicated and surrendered the power to Nancy. Nancy used the Power Cosmic herself, rushing back to the planet, where she was prepared to issue punishment on the grifters, but SG convinced her to give up the idea of revenge. Nancy then surrendered the Power Cosmic and the grifters were arrested. Afterwards, Nancy and Doreen stayed in space for a time and interacted with Beta Ray Bill, Hocky Hoof Hank, Cosmo, and the Living Tribunal.

(Unbeatable Squirrel Girl II#31) – Nancy joined Squirrel Girl, Koi Boi, Brain Drain, and Chipmunk Hunk at the mall, where they saw EpicCrimez live-streaming a jewelry store robbery. They stopped him, but Epic Crimez hit SG and Nancy with an alien gun ray that put them into hyper-speed, causing SG and Nancy to age decades in the matter of a few days. They were only able to communicate with their friends through notes before they eventually built a time machine despite being elderly, and they returned to the present at their young ages with no memories of the life they had lived in hyper-speed, though they did see the notes they had left behind for themselves and others as well as the paintings they had made.

(Unbeatable Squirrel Girl II#32) – Nancy met with Doreen and, with Tippy and Mew, they decided to invite Kraven the Hunter to a group activity.

(Unbeatable Squirrel Girl II#38) – Doreen, Brian, Tomas, Ken, Mary, Tippy, and Nancy used personal questions to determine that they each weren't Skrulls. Nancy went to visit Tony Stark, meeting his new A.I. Databus, and she determined he was real, then Squirrel Girl revealed she was alive. They had Databus generate a code-word, "voluble," that they could use to determine identity as they worked together. When Tony called the next day, saying there was no Skrull problem, he used the wrong code-word. Doreen and Nancy went to investigate and Tony tried convincing them he was the real deal, but they caught him in more lies. "Tony" put on the Iron Man armor and ordered Databus to attack.

(Unbeatable Squirrel Girl II#39) – Databus openly fired weapons into the room until Squirrel Girl and Nancy (who'd been interacting with Egg online) yelled out commands that overwhelmed his computational systems, slowing Databus down. When SG pressured "Tony" enough, she tricked "Tony" into revealing himself as a female Skrull. When they threatened to expose the Skrull, she lashed out in fear, saying she must remain a secret, then she flew away. SG tried jumping out after her, but fell several stories to the ground below.
