4. Reverse Flash

I really like this costume and I’m glad they got to it so quickly.

Eobard Thawne AKA Professor Zoom AKA the Reverse Flash is one of the best Flash villains and his costume is so elegant and such a great concept for a villain’s design. Just reversing the colors creates a unique silhouette but they went farther with crafting a unique visual aesthetic. I really love the use of black on the Reverse Flash suit. It makes it look burned, like the crash suit of someone who ran through the timestream.

Also, it should be too silly and bright to be sinister but the glowing red eyes and blurred image and voice are downright creepy.

They kept this thing going for a full season and even into some of the other shows. Some of that is obviously down to the acting talent of (SPOILER) but the mystery of the Reverse Flash is only part of the creepiness. And a lot of it is that evil-ass costume.
