Gigan is a cyborg from the Hunter Nebula in Universe M. Little is known about Gigan's origin or inner workings. Evil, cockroach-like aliens sent this cyborg monster to Earth along with King Ghidorah, to destroy human civilization.
Gigan's taskforce with King Ghidorah was foiled by Godzilla and Anguiras, and its subsequent team-up with Megalon resulted in another failure.
Gigan's latest appearance was in the 2004 Millennium film, Godzilla: Final Wars, where he is one of the main antagonists for Godzilla to fight. After Gigan is beheaded and seemingly killed by Godzilla, his alien masters recover and rebuild his body, upgrading him with claws designed like double pronged chainsaws. This time, Gigan is killed by Mothra, who sacrifices her life to kill the ancient cyborg.
