It's only shown once in the series for about 30 seconds, in the episode Nevermore. When Raven goes inside her own mind to keep the evil within her at bay, she is shown to have emotions in the form of herself in different colors of capes/boots. Her father Trigon's evil influence surfaced and faced off against her. She combined herself (default blue) with all of her other good emotions to become her pure self, White Raven. When she attacks him once, he turns into what he truly is; her, but evil. She is shown in red with 4 glowing red eyes.
I LOVED the concept, the symbolism and the glowing eyes from the day I saw the episode when it first aired a few years ago. I put it on my "eventually to cosplay" list, but since my bf Craig is an LED expert (kinda, lol), he told me he could make it happen. So we set to work, and this is the result!
EDIT: I just fixed up the editing on the pic...like adding in the missing belt jewel that had fallen off and correcting the skin tone of my hands.
Thanks! I didn't know there were others, lol. I would love to see someone actually do a good job of this...my costuming skills weren't that great when I made this >_<
AMAZING job!
