How might Wally "The Flash" West look if he was a villain? And how might Murmur look if he was a hero? Let's see!
Excerpt from "DC Nation" in the back of all DC comics with a cover date of August 2006, on Earth-Bajillion:
"With the Trickster's heroic sacrifice in the pages of CRITICAL INFINITY, his legacy is in the hands of his mute former sidekick, MURMUR. But the grim, daring acrobat is about to find out that for every legacy hero, there's a legacy villain! And there's none deadlier than the new Flash! Bigger -- and faster -- than his late namesake, this Flash is a brutal drug lord who's determined to rule Peripheral City. Is Murmur agile enough to defeat the fastest thug alive? Or will he end up as a stain on Flash's boots? Geoff Johns and Cully Hamner provide the answer in the pages of MURMUR.
...Fun fact: I almost gave Evil Flash a beer belly. Thank God I came to my senses.
I already knew I wanted to make Good Murmur a motley-clad hero, because Evil Murmur wears a jester outfit already (only it's black leather bondage *yawn* gear). I got rid of the stupid facemask because I've always freaking hated it. It just bugs the shit out of me. Simple as that. So instead I carried the clown motif through with a pale face and with dyed hair that is arranged to looks a bit like a jester's cap -- not completely, since I didn't want him to look like Sideshow Bob, but enough to convey the idea. When he's still, it would be lank and a few locks would hang over his face. I also figure that as part of his gimmick, Murmur would have a morose demeanor and never smile. Which makes total sense since he's a Geoff Johns character, and therefore has nothing to smile about.
I designed Evil Flash to be a stark visual contrast with Good Murmur. Good Murmur wears a costume, so Evil Flash wears street clothes. Good Murmur is kinda slim, so Evil Flash is brawny. And (although you can't really see it here) Good Murmur never smiles, so Evil Flash always smiles. Which is kinda creepy.
And again, no, that's not me as "Evil Flash."
