Ash's Bayleef

Ash's Bayleef is the second Pokemon Ash caught in the Johto region. She first appeared as an Chikorita.

The Johto Journeys
When Ash first met Chikorita, she was a stubborn Pokemon who just wanted to fight off Ash's attempts to catch her. After rescuing her from Team Rocket, Chikorita chose Ash as her trainer. Chikorita then started to show signs of having a crush on Ash and was jealous of Ash's relationship with Pikachu and always choosing him over her. In Chikorita's Big Upset, this jealousy was shown and Chikorita was confirmed female because Nurse Joy called her a she. When she ran off, Pikachu ran after her, but was stopped by a vine whip. Chikorita then fought the leader of the abandoned house and defeated it. She became the new leader, but not for long, when Pikachu found her, that's when Team Rocket tried to capture the both of them claiming them to be a gift for their boss: Giovanni, the leader of Team Rocket who wants to take over the world using Pokemon. Ash came, but both Pikachu and Chikorita were grabbed by Meowth's giant robot. But Ash risked his life to save them and the robot exploded sending Team Rocket blasting off. Ash then comforted Chikorita and allowed her to jump on his shoulder to ride with him and Pikachu. In one episode, Chikorita along with a few other Pokemon were captured by Team Rocket, but rescued by their trainers. In another episode, Ash told his Chikorita, Totodile, and Cyndaquil to go get the ball. They were cornered by Meowth who wanted to use them to get Ash to hand over his Pikachu, but again his plan was thwarted. In another episode, all of the gang's Pokemon including Chikorita were captured by Team Rocket, but were set free by Ursaring and reunited with their trainers. Chikorita then spent the rest of the time traveling with her trainer.

Ash snapped and yelled at her which made her very upset and she ran away. She was rescued by a kind elderly lady named Maruno. When Ash came to apologize and get her to come back with him, she refused to go with him because he had hurt her feelings and she ignored him half the episode. But when Team Rocket captured her, Ash's Pikachu, Maruno's Skiploom, and Maruno's Bellossom, Ash tried to rescue them and Bayleef soon realized that he really cared about her and together they escaped Team Rocket and sent them blasting off. She appeared often trying to help Ash in many episodes.
