Ash's Bulbasaur/History/Advanced Generation/Kanto Battle Frontier

Bulbasaur later returned in The Right Place and the Right Mime, where May decided to leave her Bulbasaur at Professor Oak's so she could learn from Ash's Bulbasaur.

In Gathering the Gang of Four!, Ash brought it to his team alongside Charizard and Squirtle to battle Brandon at the Battle Pyramid. After Brandon's took down Charizard, Ash's Bulbasaur was sent out to fight in the next episode. It took damage from the powerful Dusclops, including a Confuse Ray which sent the vines out of control and caused them to attack Bulbasaur and Ash. Bulbasaur responded to Ash's cries and broke out of confusion, leaping into the air and taking down Dusclops with Solar Beam. After took down Squirtle, Bulbasaur was sent back out. After taking damage from moves and responding with Razor Leaf and Vine Whip, a double Solar Beam knocked both Pokémon out. After Ash won, Bulbasaur returned to Professor Oak's Laboratory.
