Miguel O'Hara was just a teenager who got his powers from energy from the Time-Storm and spider DNA and out for the first time as Spider-Man and didn't know how to use his powers completely. Though he was nearly killed, Miguel O'Hara managed to rescue Peter from The Scorpion, and the two heroes took down the freak of science. Later Miguel fought the Human Torch, an Atlantean with control over fire; Relur soon offered to train Miguel in the art of combat.
He was killed when Morlun began to hunt down the various Miguel O'Hara Spider-Men across the Multiverse as part of the Great Hunt. Morlun attacked Miguel at his home while he was sleeping, consuming his essence, before overpowering and murdering his father, George. Miguel's death was felt by both the Miguel O'Hara harbored in Earth-616 and Miguel who had joined the Exiles.
