 He was associated with a new superhero team, The Blasters, in various comics until 1993, when he lost his powers and became a main character in the "Hourman" comic book.
 After the cancellation of "Hourman" in April 2001, he became a main character in the "Young Justice" comic book beginning in December 2001.
