This may already be common knowledge, but I can't find anywhere on the 'net it was mentioned. I was watching the JLU final season DVDs last night, and the episode "Dead Reckoning" (with Deadman) had Luthor and co. appear at Nanda Parbat with an army of guys dressed in blue. I feel really dumb about it, but I did not realize until last night that these guys in blue were probably the Timm-verse version of the Firestorm villain Multiplex. Given that Multiplex and Firestorm were created in the same nuclear accident, that gives some potential evidence that Firestorm was definitely kicking around the Timm-verse. As a big Firestorm fan, I thought was neat.
