This guy reminds me of my cat (in terms of body weight.) Mine has the ability Thick Fat and is EV trained in Defense. It knows:
Attract: I don't know what could possibly be attracted to this thing. Causes infatuation.
Body Slam: Good power, STAB, high accuracy, good chance to paralyze.
Swagger: Confuses the foe. Works well with Attract.
Charm: Gets rid of the attack the foe gained with Swagger.
