[Request] A cool Yin-Yang type "demon"

http://imgur.com/tFJoy1p (i made of what i have in mind kinda)

• Yin-Yang type character (gender-less)
• wants to find the strongest opponent out there, wrecks havoc without care
• expressionless eyes, no mouth/facial features (only eyes)
• sword and blaster
• generally bad-ass :P
• i don't entirely want it to look humanoid, but exaggerated part for strength could help (want it to look like its fast)

Thank You guys very much before-hand :D
