Thailog (Voiced by Keith David) is a gargoyle who is the clone of Goliath in Gargoyles. Thailog was conceived when a Steel Clan robot was activated by Xanatos for the specific purpose of opening wounds in Goliath's skin. Goliath destroyed the robot as Elisa looked on, but not before it scratched bloody lines down his chest. Owen Burnett showed up right on cue, and treated the wound, and in doing so, extracted blood samples, complete with DNA. He told Goliath and Elisa that the robot had activated due to a freak overload in it's power matrix. They believed the lie, and the incident was forgotten.
