Ash's Bulbasaur/History/Advanced Generation/Hoenn

Bulbasaur was seen in Showdown at the Oak Corral, and was one of the first Pokémon to realize there was something wrong. It later defeated Butch's Hitmontop and used a Solar Beam on the whole group.

In Hokey Poké Balls!, May showed her to Professor Oak, which made Ash decide to bring his Bulbasaur over for a visit. When the Poké Ball arrived though, it wouldn't open, making everyone believe that the Pokémon Center's balls had been stolen. It was revealed to be Team Rocket, who accidentally dropped Ash's Bulbasaur while escaping. The two Bulbasaur teamed up to stop Team Rocket, with Ash's Bulbasaur teaching May's along the way. Once they found Team Rocket, the Bulbasaur battled against them, with Ash's Bulbasaur protecting and teaching May's how to fight. After rescuing the Pokémon, Professor Oak called back and asked for Ash's Bulbasaur to return and stop the Water and Grass Pokémon from fighting. Ash sent his Bulbasaur back to Professor Oak's Laboratory as May's Bulbasaur appeared to have made a positive change from the experience.
