Round One - Begin!

Ash goes in to sign up for the Pokémon League. In the Pokémon League competition, each participant must battle in all four arenas. After sign up is complete, he ends up battling in the water arena. Ash meets Gary before the battle, who is very confident as usual. Gary enters his battle and wins it. Ash meets his challenger in the water arena. His name is Mandy, and he is quite confident he will win as well. Before the battle, Ash gets Krabby from Oak through an exchange system. Then, he heads towards the arena for battle. Ash enters the arena. Just as the battle is about to begin, Team Rocket is in the announcer's stand cheering him on. They are soon carted away by a group of five Officer Jennies. Ash fights the battle hard. Using his Krabby, he manages to win the first battle which then evolves into a Kingler. Continually fighting the battles with Mandy's Pokémon, Ash wins them all much to the surprise of Mandy who was sure he would win. With the first Pokémon battle won, Ash faces the next arena.
