Harley is one of May's rivals in the "Pokemon" anime. He's a vain, flambouyant, effeminate coordinator from Slateport City of the Hoenn region. He's also a sneaky, devious villain who will stoop to any low to win a contest. He despises May for (in his mind) not thinking highly enough of him and his signature Pokemon, Cacturne. Though he always strives to beat her through cheating and dirty tricks, May usually always comes out on top, which only fuels his anger and desire for vengeance. He even helped out Team Rocket in one episode.
