In Principal Raymond Warren's homestead at night, Sally Avril (who was raised by Warren after her parents' death) is practicing some gym exercises until a strange meteorite crash-lands in the yard. Just as Sally inspects it, the meteorite explodes and lets out a mysterious gas around her neighborhood. Only Sally is affected by the gas, and she is transformed into a beastly creature (off-screen). Frightened by her transformation, she flees, but not before a S.O.S. disc Peter Parker shared with her is triggered, alerting him of the situation.

Later on, Peter is with Sally's boyfriend and Tony Stark's son Cameron (who operates as the S.H.I.E.L.D. Academy trainee Lightyear) reviewing the yard, where Cameron's armor detects Terrigen radiation. Peter and Cameron soon analyse a sample of Sally's DNA (which they previously extracted) and discover that she is a Mutant/Inhuman hybrid, whose Mutant powers were rendered dormant by the inactivity of her Inhuman DNA until she made contact with the Terrigen Mist triggered by the meteorite, and begin to search for her with help from Tony / Iron Man. Meanwhile, Mary Jane Watson, who happens to be the half-human, half Titanian Tiger champion Tigra, is having a training season with her younger cousin Kitty Pryde / Shadowcat until they encounter Sally, who was transformed into a humanoid feline with snow leopard aspects, and grant her shelter in the X-Mansion. As she practices her new feline abilities with Mary Jane, Sally sadly complains that she tried to, but cannot reverse to her human form like Mary Jane and Kitty can. Peter and Cameron arrive and offer to help find a solution for Sally until they are attacked by Magneto, who is bent to kill Sally and "end the peace between Mutants and Inhumans".

Spider-Man, Lightyear and Shadowcat, objecting to Magneto's terms, stand in Sally's defense and fight him, allowing Sally to flee with Tigra. In Oscorp, Warren is with Norman Osborn seeking his help in finding Sally and dispose of "the monster who kidnapped her", with Osborn eventually hiring Kraven the Hunter for the job. Overhearing this through a tracker she and Peter implanted on Osborn during the Living Brain incident[2], Tigra and Iron Man take Sally in to a safe place where Sally can have more time to practice her abilities. Attempting to help Sally in reverting back to her human shape through hypnosis, Mary Jane has a vision of Sally's past, on which her parents worked to stop a war between Mutants and Inhumans which was orchestrated by Norman Osborn, who planned to eradicate both sides with a terminal bomb hidden in the battlefield. Sally's parents eventually sacrificed themselves to stop the bomb, which led to the Mutants and Inhumans making peace with one another, as humans were made to sign the Superhuman Preservation Act, which would get humans to make peace with the two factions. Tigra and Sally rush to Oscorp and find evidences to expose Osborn, as Sally also decides to make her transformation public knowledge. They are confronted in the rooftop by Kraven, but Sally decides to battle him alone, because she is "tired of running".

Later after defeating Magneto, Spider-Man, Lightyear and Shadowcat rush to help Sally, who is having a fair fight with Kraven which she is close to win. Kraven attempts to restrain Sally with his traps, but Sally overcomes them by revealing that she can also generate and manipulate ice and cold, effectively defeating him. As the young heroes congratulate her, Sally is confronted by Warren, whom she berates for having lied to her about her deceased parents for years before allowing Spider-Man and Lightyear to reveal her status as a Mutant/Inhuman to the public, introducing herself as "Snow Leopard". As Warren faces accusations for his role in the deaths of Sally's parents, Magneto is taken to the Mutant Council by Beast to stand trial for defying the Mutant/Inhuman Peace Treaty, while Kraven is taken to prison by S.H.I.E.L.D. agents. Sally bids a emotional farewell to her fellow cheerleaders in Midtown High before she is introduced by Iron Man and the Fantastic Four to Pegasus Z, a paradise island created by Thor and Groot for homeless Mutants and Inhumans to be their safe haven, and Sally expresses herself eager to explore. As he and Cameron are happy that Sally still has a life to live (and will also be enrolling at S.H.I.E.L.D. Academy alongside Cameron), Peter is also suspicious that Osborn was not the only client Kraven had answered to. Meanwhile, Kraven contacts his other benefactor: the Latverian emperor Doctor Doom, while apologizing for failing on his mission. Doom, however, replies that his assignment for Sally's capture was "just a vessel", as his real mission, which was to allow Doom to gain access to Oscorp's database, was a success[3].
