Flashback, a Time Traveler
Flashback sometimes felt like the most privileged SilverHawk. As an advanced futuristic lawman, he could travel in time to stop past and future ravages done to his brother and sister SilverHawks by Hardware and other Mob members. His ability had certainly saved the SilverHawks and Limbo on multiple occasions.
Time travel surely was an interesting experience. Sometimes Flashback was afraid he wouldn't be able to return to his own time, though. Fortunately, his talents were always enough for him to return safely so far. As long as Flashback existed, the Mob couldn't get away with the murder of the SilverHawks.
