Kal-El, Van-Zee, the Nightwing of legend, Kara Zor-L and Christopher Kent.
It is likely that Kal-El and Van-Zee were never Nightwing in modern continuity, though.
The rendition of Bart in the Flash costume looks better than the one Wally is in right now too.

Thanks for posting that Impulse. That costume is a 1000 times better and even opens a small window of hope for even better costumes along the same lines. I was just typing how disappointed I am in Red Robin's look in the Damian thread.
Fair enough it wasn't really a problem at the time of KC, but with the JSA being prominent for 10 years now, I don't think it should have been used again in the first place.
