It is unknown why Devack joined the Dark Signers, though he appears to have been one of the earlier members. He first appears out of the original [[Ener-D]] Reactor arriving by helicopter to free Greiger from custody, as his transport guard's souls have been absorbed by "[[Earthbound Immortal Asla Piscu]]". Roman then invites him to join them and get revenge on [[Rex Goodwin]] for the destruction of his home town. They later pick up [[Misty Tredwell]] and [[Carly Carmine]] to return to the Ener-D reactor.
