Spider-Man (Age of Apocalypse)

Spider-Man is the alternate universe counterpart to Peter Parker.

Biography
Through means unknown, this Spider-Man got his spider powers during a war between mutants and humans as there was never anyone who led the mutants in peace.

He was part of the Avengers led by Captain America and consisting of Iron Man, Giant Man, Wasp, Black Widow, and Hercules. Together they battled the X-Men led by Magneto.

During the battle, two more time travellers, Bishop and Shard, appeared on the battlefield. They took Wolverine and Storm with them as they jumped to another time.

Background
Spider-Man's appearance was merely a cameo with no speaking part.

In the Comics
Apparently, there is no Spider-Man in the Age of Apocalypse universe (a backup text in Universe-X implies that he died before having his lab accident).
