you are a Pokémon Trainer who is now in the Hoenn region,you tried to stop Team Magma,but...failed,Groudon is now free,it didn't happen as Maxie expected,you then decided to invade Team Aqua's base to stop Kyogre from being awakened as well,because if not, Groudon and Kyogre would start a fight that could destroy all of Hoenn,when you enter the base you see Kyogre already awakened by Archie,Team Aqua leader,laughing sadistically,already considering that he won and that Kyogre will expand the oceans,now you have to stop Kyogre before it escapes and goes to battle against Groudon,now try to stop Kyogre!This is your last chance to save Hoenn!
