Ok, just theorymoning at the moment, so I haven't tested it, but at least it's creative!!

Counters the amount of Fighting Pokemon in UU quite nicely, with its nifty 4x resistance. He is also quite fast too, so he can outspeed Fighters and set up a Reflect and stall them. LO Jolly Hitmonlee's Stone Edge does 54.05% - 63.66% after Reflect is set up, which is pretty cool, since you can just Roost it off, and Stone Edge does less after Roost as well.
