I could do with a bit of help designing this particular boss of mine, and I figured this would be the appropriate place for me to ask.

I know it's crap, but bear with me here.
Essentially, I feel as though he's just too basic and bland in comparison to my other ideas. My intention was to create a Robot Master - Optic Man - who could absorb light via the red lenses on his body, then refract them and release them in the form of huge laser beams. Would anybody be so good as to suggest how I might be able to make him look more, well, interesting and unique?
NB. Please don't bother pointing out the "NES colour limitations" thing, I really don't care.
