The best choice would be Megahorn as it does not have the disadvantage of locking such a slow Pokemon into one easily Countered Move such as Outrage, while also offering more Coverage other than what Earthquake already does. In addition to that, he would need Megahorn to put a decent dent into Tangrowth, the premier Physically Defensive Wall of the RU TIer and one Pokemon that he can counter with the Sap Sipper Ability. Here is a better Set that can turn your Bouffalant to a manly killing machine:
Super Manly Killing Machine
Bouffalant (F) @ Choice Band
Trait: Sap Sipper
EVs: 252 HP / 252 Atk
Adamant Nature (+Atk, -SAtk)
- Head Charge
- Megahorn
- Earthquake
- Reversal
A manly combination of Bulk and Offense that is designed to counter Grass Types such as Tangrowth and Lilligant that terrorize the rest of the Tier. The given EV Spread grants him the power needed to KO (overkill) such threats while putting a hole into anything that trys to switch in, while also making him be able to take a hit or two before being KO'ed himself. Head Charge is his deadly STAB Attack while Earthquake is there to remove the Pokemon that resist it. Megahorn is another Coverage move that KO'es Grass Type. Reversal is overall a better choice than the standard Superpower as it does not lower his Bulk or Attack, while embracing his low Speed and turning the tables against a powerful Attacker.
