He Keeps Saying He's the Flash

"He Keeps Saying He's the Flash" from Flash: The Fastest Man Alive #11 (DC, 2007) by Marc Guggenheim, Tony Daniel and Art Thibert

I was (mercifully?) out of comics when they aged up Impulse and turned him into a brown-haired Flash, giving him a short-lived book that suffered, from the looks of it, from constantly shifting art teams. It was cancelled at #13 to herald the return of Wally's book (the numbering continuing from #231), so perhaps it was always meant as buffer project (like, say, Superior Spider-Man), but DC solicited it through issue #15. Yeah, looks like there was one of DC's patented "plans" in play. I'm fine with Impulse growing up to become the Flash, but it does mean we lost Impulse as a much-loved character in the DCU, AND his short stint as an adult ended with his death at the hands of the Rogues' Gallery, villains never really depicted as murderers. It went against the grain and wasn't a story that built up the DCU as much as it destroyed elements of it. Bart would  return later, but that just makes the whole exercise unnecessary and meaningless.
