During the 1990s, Jordan also appeared as a villain. The story line Emerald Twilight saw a Jordan traumatized by the supervillain Mongul's destruction of Jordan's hometown Coast City, adopt the name "Parallax", and threaten to destroy the universe.[2] In subsequent years, DC Comics rehabilitated the character, first by having Jordan seek redemption for his actions as Parallax, and later by revealing that Parallax was in fact an evil cosmic entity that corrupted Jordan and took control of his actions. Between the character's stint as Parallax and his return to DC Comics as a heroic Green Lantern once more, the character also briefly served as the Spectre, a supernatural character in DC Comics stories who acts as God's wrathful agent on Earth.
