Ash's Bayleef/Anime/History/Other series

In Showdown at the Oak Corral, she was seen helping to feed the Pokémon at the ranch.

She was reunited with Ash in The Right Place and the Right Mime, where she rescued him from his stampeding, who had carried him off in their excitement.

In An Old Family Blend!, after briefly being stolen by Team Rocket, Bayleef escaped from her ball and went looking for Ash. Eventually, Bayleef thundered out of the trees and tackled. Then, she found Ash and tackled him too. When he tried to return her to her Poké Ball, she took it in her mouth, wanting to spend more time with Ash. She later helped destroy the hands of one of Team Rocket's mechas, and afterwards was sent back to Professor Oak's lab. Bayleef was not seen participating in the Lily of the Valley Conference.

Bayleef was reunited with Ash in The Dream Continues!, where she and the rest of Ash's Pokémon posed in a group photo with him.
