Chesnaught with his hidden ability Bulletproof is a nice option. Very nice physical bulk with an impish nature, and has a nice move pool. It's grass/fighting, not the best "wall" typing, but it's pretty good.
I'd run it like this (just realized this is from 2012 LOL)
252hp / 252 defense / 4 sp defense
hope this helps even though I'm late LOL
