Impulse is a legacy name used by young side-kicks to the Flash, members of the Flash Family. The name was originally used by Bart Allen, a teenager from the 30th Century who worked alongside Wally West. West gave him the name because growing up in a virtual reality simulation gave him poor impulse control, and Max Mercury later took him in as a student. Bart eventually graduated to become Kid Flash during A Kid's Game. Irey West began using the name when her connection to the Speed Force was strengthened during The Flash: Rebirth. Impulse was created by Mark Waid and Mike Wieringo, first appearing during Zero Hour in The Flash (Volume 2) #92. (1994)
