I'd strive to be the very best like no one ever was. And I'd also catch 'em all.
I would also be kind of like Ash, in that I would never evolve my starter Pokemon, Squirtle. I would have a Kirlia and Gardeviour which I would ravage every night, impregnate, and have little Pokemon children with. I would also have a Gallade, a Garchomp, and a motherfuckin' Hitmonlee who I'd spar with infrequently.
I'd also make love to all the female gym leaders causing them to yearn for my cock.
