I find it perplexing that you can design these unique and well-defined side villains and still have Deviot as your main villain.
So yeah, this guy is pretty cool looking, the color scheme works really well and his body is nice and solid. Don't know why he's called Quake, though, he doesn't bring to mind any sort of seismic activity, and his description doesn't make it work.
I can't say I care for the blades, they're pretty generic villain fair, even if you attached them a bit more cleverly than the norm. I dunno what would be a good idea since I can't recall your villain line-up offhand, but I think some form of blunt force implement would be a good replacement, and better match his name.
