I protest the inaccurate portrayal of rabbits. That's the most foul, cruel and bad tempered rodent you ever set eyes on! I know, because I keep one of them furry beast as a guard bunneh. Aye, guard bunneh lass/lad. Vicious beasties that would sooner rip yer to bits as look at yer!
But I suppose choosing a rabbit to depict Razer on a personality basis makes sense. Both a rage-filled creatures. Not something silly like helmet appearance, eh?

P.S. I had LOADS of fun using my rabbit as a live model. He kept on staring at the camera with this deranged, wide-eyed hellish stare. Pierced my soul it did.
