Rudy (Japanese: ジギーZiggy) is the Gym Leader of Trovita Island, who gives trainers the Spike Shell Badge if they beat him. While the gang is on the way to the island they spot a little girl, who happens to be Rudy's little sister. Misty saves the little girl and Rudy falls instantly in love with Misty. Ash and Tracey were confused about this but Misty was excited about it. Eventually Rudy wanted Misty to stay with him for good. However in the Japanese version, he asks her to marry him. Misty eventually, but indirectly declines. He sees that she actually loves and cares for Ash more than him. Knowing it's the right thing to do, he lets her go and continue her journey.
Ash was eager to challenge him and get his next Orange League badge, but first Ash had to pass a test: to hit every bulls-eye with a Pokémon attack while on a boat moving down a river. He used Pikachu, Squirtle, Bulbasaur and Charizard. He eventually passes the test and battles Rudy who tells Ash to use three element Pokémon and he will use the same type. Ash chooses Grass Water and Electric.
