Superman, Batman, and Max Mercury have all been cited as giving comic-book speedster Bart Allen the name Impulse. Batman most famously in Impulse #50, and Superman just recently in the previews for next month’s All-Flash #1. But who named him originally?
The name first appears on the cover of Flash #93 (August 1994), with an out-of-control Bart Allen fighting the Flash. The cover is captioned, “Brash Impulse!” Over the next few issues, Wally West’s inner monologue refers to Bart as being impulsive, or (at one point) as “Mr. Impulse.”
It first appears on-panel as a name in Zero Hour #3 (September 1994), when Bart meets Superman for the first time, but Bart introduces himself as Impulse. Dan Jurgens writes.
