Tomi Shishido is a member of the
Hand and
Hydra and a powerful
mutant, leading the extremist mutant society
Dawn of the White Light. As a child, he possesses near superhuman levels of intelligence, being able to speak, walk, read, and write by the age of one. At age 13, Shishido formulated a mathematical formula that proved the existence of the
One-Above-All and manifested the mutant ability to petrify others by sight. The media dubbed him "the Gorgon", after the
Gorgon of
Greek mythology. Shortly after, he became the leader of the Dawn of the White Light, a terrorist cult. At age 18, Shishido sought to join the Hand and killed his family to prove that he was ruthless enough to do so. After finding the Hand's sanctuary and killing all of its guards while blindfolded, Gorgon pledged allegiance to the Hand. When the Jonin questioned his dedication, Gorgin fatally wounded himself with his sword to prove himself, telling the Jonin to resurrect him before dying. After being resurrected, Gorgon was recruited into the Hand. During the "
Dark Reign" storyline, Hydra forces the Hand to resurrect Gorgon using the fragments of his body. In
Fear Itself, Gorgon joins
H.A.M.M.E.R. and
Norman Osborn's incarnation of the
Dark Avengers, during which he poses as Wolverine. He and the original
Madame Hydra secretly plan to kill Osborn if their co-conspirator proves to be too dangerous and use the Dark Avengers to cause discord by serving as a voice of the "disenfranchised" unsatisfied with the status quo. While impersonating Wolverine, Gorgon uses false claws that are a part of his costume. Gorgon is among the mutants invited by the
Quiet Council of Krakoa to live in the newly established mutant nation of
Krakoa, provided he no longer holds any grudges against his fellow mutants. He accepts and later even drinks a beer with Wolverine during a party. Gorgon becomes part of Krakoa's security force, the "Great Captains of Krakoa", and serves as a bodyguard for
Charles Xavier,
Magneto, and
Apocalypse at political events. Gorgon participates in
Saturnyne's
X of Swords contest against
Arakko, where he single-handedly turns the tide of the tournament in Krakoa's favor by defeating 13 of
White Sword's one hundred champions before being killed by White Sword himself. White Sword offers to resurrect Gorgon as one of his champions as a reward for his bravery, but he declines and is praised as a hero upon his death. Gorgon is later resurrected by
the Five, but his mind is damaged because he died in
Otherworld.
Fabian Cortez tries to take advantage of his brain damage by taking him to
Central Park and strengthening his telepathy so he could hear all the hateful things people are thinking about him. Cortez hopes to use Gorgon to kill all these people so he can bypass Krakoa's law against murder. However,
Nightcrawler intervenes and stops Cortez. Gorgon also unsuccessfully applies to be a member of the X-Men and the Quiet Council of Krakoa. ==Powers and abilities==
