Practice, I guess. My mom, dad, Uncle Ben, Mr. Stark. Now Happy. I've... I've lost a lot. But my Aunt May says... used to say... that if we don't keep smiling when they can't, then we might as well just be gone, too. And... Well, they'd want us to keep going.

History
Peter Parker's history was identical to that of his Earth-199999 counterpart until Janet Van Dyne was infected by a virus from the Quantum Realm. Janet infected her husband Hank Pym when he tried to take her out of the Quantum Realm which resulted in the spread of the virus around the world. Parker's knowledge of horror films from his A/V club at high school allowed him to survive the virus.
Two weeks into the outbreak, he had formed an alliance with Okoye, Sharon Carter, Happy Hogan, Bucky Barnes, Hope van Dyne, and Kurt. After rescuing Bruce Banner and the Cloak of Levitation from zombies, Parker explained the situation to Banner, but Okoye interrupted, explaining that they had received a message from Camp Lehigh, New Jersey. The group drove to Grand Central Station to take a train there. Okoye suggested the group split up, despite Parker's protests that in horror films, splitting up is a bad idea. Parker worked with van Dyne, Kurt, and Banner to start the train, learning to his dismay that Happy was killed, and was nearly overwhelmed by zombies before the Cloak saved him.
After Hope was forced to kill a zombified Sharon and became infected in the process, she asked Peter how he remained to upbeat despite everything, to which Peter admitted that he had lost several figures in his life, like his parents and Uncle Ben, but follows his late Aunt May's advice to smile throughout tough times. When the train stopped in front of a zombie horde, Hope, inspired by Peter's words, became giant and carried the group to Camp Lehigh, sacrificing herself to save them.
There, the group met the Vision, who explained that he had experimented with the Mind Stone to find a cure, having restored Scott Lang's head to normal. Parker was surprised when Banner revealed that they weren't the first survivors, but Bucky returned with an injured T'Challa and Vision revealed that he had been luring survivors to feed a zombified Wanda Maximoff. Parker assisted in fighting Wanda, but Vision led the group out of the base before destroying it to hold her off and leading them to a Quadjet to leave. Vision then removed the Mind Stone and gave it to Banner, who gave it to Parker before transforming into the Hulk and fighting Wanda and the zombies.
After falling asleep from the journey, Parker woke up and had a heartfelt conversation with T'Challa about losing people. They reflected on how they were humanity's last hope before arriving at Wakanda, unaware that it was already ravaged by zombies and that an undead Thanos was there with the other Infinity Stones.[2]Attributes
