Dr. Sato was a guest at Xanatos' Halloween Masque party in 1996, and there, after being alerted by Brendan Quarters, he discovered the truth about the gargoyles, and tended to Goliath's extreme injuries, after he was near-fatally wounded by Thailog. ("Bash")
Voice Actor: Robert Ito
Jay Sato's first name has never been mentioned on screen. His first name was revealed in the script of the Radio Play presented at the 2007 Gathering of the Gargoyles and is thus canon-in-training.
