Ash's Bulbasaur/History/Original Series/Orange Archipelago

In Navel Maneuvers, Bulbasaur was used in the second round of Ash's Gym challenge against Danny. It attempted to help Pikachu carve a frozen geyser into an ice sled, but was unable to keep up with Danny's team until completed it in a few short Flamethrowers. Bulbasaur was later used again in the final round, where it helped Ash, Pikachu, and in the sled race down the cliff, using its vines to steer. Thanks to everyone's cooperation, Ash was able to cross the finish line first, winning Ash the challenge and earning him the Sea Ruby.

In The Mystery Menace, due to one of Team Rocket's schemes, Ash and his friends found themselves in the sewers of Trovitopolis, where they came across a giant vined creature. Ash sent out Bulbasaur to attack the creature, but it used its vines to deflect Bulbasaur's Razor Leaf and then proceeded to grab and take Bulbasaur underwater. After learning more about the vined creature from the Mayor of Trovitopolis as well as about his plans to exterminate it, the group decided to head back to the sewers to save the creature and Bulbasaur from the Mayor's personal SWAT team. With help from, Ash was able to find Bulbasaur and its captor, a mutated giant Bulbasaur that had been abandoned by the town's Mayor. Bulbasaur later saved its new friend by helping it sending the Mayor and the SWAT team flying.

In Misty Meets Her Match, Ash had Bulbasaur, alongside Pikachu and Squirtle, destroy a succession of targets in order to challenge Rudy to a Gym battle. The next day, Ash used Bulbasaur in the second round, the round, of his Gym battle against Rudy, where it fought against Rudy's. Exeggutor was able to dodge Bulbasaur's Razor Leaf attacks using its dance moves and then knocked Bulbasaur down with Egg Bomb. While being cornered by Exeggutor, Bulbasaur quickly saved the battle by putting Exeggutor to sleep with Sleep Powder. As Exeggutor was unable to battle, the second round victory went to Ash.

In Enter the Dragonite, Ash used Bulbasaur as his fifth Pokémon in a Full Battle against Drake for the Orange League championship. It faced off against Drake's. Bulbasaur managed to shake off a Thunder Shock and then hit Electabuzz with Razor Leaf. Its leaves, however, were then destroyed by Thunderbolt and although Bulbasaur managed to get a hit in with Tackle, it was struck by Electabuzz's Thunder Punch, knocking it out. Drake was eventually defeated and Bulbasaur joined the rest of Ash's team in the Orange League Hall of Fame.
