Last month, the villain Reverse-Flash made his big debut in an episode of the CW's "Flash" titled "The Man in the Yellow Suit." Now that the super villain has made his small screen debut, "Flash" concept artist John Gallagher has revealed a handful of promo pieces for the character via his Deviant Art page.

A caption for one of the photos labels the image as an "Internal promo piece for the show. Now that RF has made the scene, all good to reveal a few vis dev looks for him." The images present a Reverse-Flash that's pretty close to the final look that made its way onscreen last December.

Those of you that haven't caught up with "The Flash" might still be in the dark about the villain's alter-ego, so beware the spoilers that follow. With the man in the yellow suit's identity finally revealed after half a season of mystery, "Flash" actor Tom Cavanagh was glad to finally be able to discuss his dual role in a recent CBR interview. Of course, it's possible that the villain's identity is a bit more complex than that, as Cavanagh hinted.

"Can it be that simple? As a betting man, I would wager that it can be that simple," said Cavanagh regarding Reverse-Flash's secret identity. "On the other hand, I'm not a keeper of the flame. These guys no doubt have stuff up their sleeve as we progress. For my own edification, I'm so very happy to finally be able to talk about it. It's the reason I signed on, and for six months of just dodging and parrying and deflecting, I'm happy to be able to talk about Harrison Wells and the Reverse-Flash, finally."

"The Flash" returns to the CW with new episodes starting tonight.
