Most people use Technician on Hitmontop, but Intimidate is the better of the Abilities if you are running a Rapid Spinner on it, which got it to the #1 used UU Pokemon in PO. Here is a Rapid Spinner variant of Hitmontop, who is better than Technitop:
EVs: 252 HP, 232 Defense, 26 Sp. Defense
Impish Nature:(-Sp. Attack, +Defense)
- Rapid Spin
- Close Combat/Hi Jump Kick
- Stone Edge
Intimidate ruins Physical Sweepers like Heracross and Flygon by lowering their Attack stat, combined with its EV Spread to Wall them really well. Rapid Spin is there for obvious reasons, to spin away Hazards. Toxic ruins Walls and crippled Physical Sweepers, which works well with Hitmontop. Close Combat and Hi Jump Kick are chosen STAB, it is preferred that you run Hi Jump Kick so you don't ruin your Defenses, which Close Combat does. Stone Edge is nice Coverage overall, although Sucker Punch is nice to cause serious damage to Ghost Types, who ruins Hitmontop.
