Reshiwott, I've beaten it already, and once I have my Jirachi and army of Gardevoirs/[M] Kirlias/Bagons, I'll restart so that I can get more Legendaries + Jirachis.
Reshiwott, (Just some Uber crud. ) Kyogre, Latias, Gardevoir (Soon to be replaced with Jirachi when I get the Link Cable), Toasty the Zigzagoon (For the Pickup Ability), Mudkip, and Rayquaza.
