It seems that I can't read this as anything but "e-violate", which sounds... akward to say the least xDEviolite is hands down one of my favorite translations in the game.
Typing is too crappy IMO; its physical bulk is nice but ground and fighting attacks are everywhere. Seems like a waste of space since it's slow as well.Anyone considered Lairon? Its mammoth defense with this as well as its only 10 less HP and Sp. Def than Aggron mean that it is good at Metal Burst.
Roar/SR/Toxic/Metal Burst seems the best option I guess.

Stone Edge/Rock Slide
Explosion
Comes with decent Physical Bulk, Stealth Rock, and a decent attack stat and also a built in Focus Sash. Set up SR, and then blow up if you can't do anything else. EdgeQuake is for STAB.
Whatever happened to the still-crappy rhydon? Explosion on a defensive pokemon is heavily counter-intuitive.
