I thought this guy would evolve from Tauros, but it looks like that is not the case.
EVs: Attack, Defense, HP Nature: Adament
Afro Break: Double-Edge pretty much. STAB+Reckless+120 base power.
Wild Bolt: For use with Reckless.
Reversal: This guy is going to have low HP after only one or two attacks, so this is a great move to use.
Megahorn: A powerful Bug type attack, use in case you don't want to damage yourself.
