Michael

Human-Wraith Hybrid

Pegasus Galaxy

Thrown off Atlantis' Control Tower, fell thousands of feet

Captured by the Atlantis expedition, experimented on & turned into a human
Had no memories, given the name Michael, discovered the truth & escaped
Wraith DNA started returning, as did his memories, became a hybrid
Experimented on humans, created more Hybrids & led a failed invasion of Atlantis
