Gideon was almost killed when the Phoenix engulfed Washington in order to kill the Followers of Apocalypse. Gideon survived and became the leader of the new members of the Followers of Apocalypse.


  • Power Mimicry: Gideon was a mutant with the ability to temporarily endow himself with superhuman abilities by assuming the superhuman energy signatures and genetic templates of superhuman beings in his vicinity. Apparently he could even duplicate the superhuman physical capabilities of robots. Exactly how Gideon scanned the genetic templates and signatures of other superhumans is unknown, but it has been theorized that it was psionic in nature.
  • Regenerative Healing Factor: As part of his own natural genetic mutation, Gideon possessed an accelerated healing factor. He could regenerate damaged or destroyed bodily tissues much faster and more extensively than an ordinary human. For instance, multiple gunshot wounds to his torso fully mended within a matter of minutes. Gideon's natural healing factor also rendered him highly resistant to most toxins and poisons, as well as an immunity against all known diseases. On his own, however, his healing powers were insufficient to fully regenerate missing organs or severed limbs. However, it is possible that Gideon could have fully regenerated such tissue by temporarily absorbing the abilities of a being that possessed a sufficiently developed healing factor.
  • Superhuman Longevity: As an External, Gideon's natural aginc process was altered dramatically. From the time he seemingly "died", Gideon appeared to have aged very little, if any at all. Gideon is more than 500 years of age.


Gideon was an excellent combatant and had extensive training in multiple forms of armed and unarmed combat.
