Lim Jong Chul ~This was my original inspiration for Rafikke. She's only gotten beefier and uglier since.
I like the idea of heavy armour with a dark hood, but it could reduce the overall character's design as you couldn't see the character. The idea of using some sort of lightning and a shield is quite interesting.
