Rivals

Whether you love them or hate them, rivals are an essential part of life, for competition promotes evolution.
Here are some of Ash's biggest rivals(+ Barry, lol) imo. Note that I specifically left out people who he only met at a league and ended up losing to there. So no Ritchie, Harrison ect.
Who is your favourite rival? I'm going to have to say Paul because they had the most and (imo) best battles, the whole Chimchar plot ect. The story line with Paul was just amazing, for Pokemon standards anyway and is a big reason why my favourite series so far is in fact, Diamond and Pearl.

EDIT: OH GOD I FORGOT MORRISON'S PONY TAIL THINGY. On 2nd thought maybe I should just stay quiet, I mean who really notices that? Keep your eyes on the other fabulous men! :]]]
Let's just say it's the angle that hides it. that's usually my answer to things.
