XY Rules
Pokemon Master
He's not...only in BW.
Literally every other region, he has steady progression and got consistently stronger, and smarter (in regards to Pokemon stuff) along with becoming more mature and less cocky, annoying and arrogant.
He only loses early on because he always starts off with weak Pokemon, but it has nothing to do with him (unless he's unfocused for whatever reason). But he's always been consistently progressing (excluding BW).
