Groudon and Kyogre are fighting again, not because of any world ending situations or one of the teams getting them to. no. it's because they both want one Pokémon trainer to be their master and neither want to share.

Said Pokémon trainer is you. You've been put in the middle of the two legendries fight. Ash and his friends, Brock and Misty, have managed to get you out of the battle field, while the two Legends are in the middle of it, and hand you your previously lost Pokeballs to aid in escape.

"C'mon, let's go!" Ash said.
