In Grass Hysteria!, May was kidnapped by a hungry Skarmory and ended up lost in a reserve for Grass-type Pokémon called the Forbidden Forest. There, she met a clumsy Bulbasaur trying to pick flowers. Bulbasaur warmed up to May after being saved from a fall, but the other Pokémon in the reserve repeatedly tried to attack May. However, Bulbasaur explained to Venusaur, her parent and the ruler of the Forbidden Forest, that May was a friend. Before May had to leave, Bulbasaur decided to stay with her.
In Hokey Poké Balls!, May sent out her Bulbasaur to enjoy the sights as they went through a city. Bulbasaur quickly gets distracted by some flowers in a truck and has to be rescued as the truck speed off. Later at the Pokémon Center May shows Professor Oak her Bulbasaur, which makes Ash decide to bring his Bulbasaur over for a visit. When the Poké Ball arrives though it won't open, making everyone believe that the Pokémon Center's balls were stolen. It is revealed to be Team Rocket, who accidentally drop Ash's Bulbasaur while escaping. The two Bulbasaur team up to stop Team Rocket, with Ash's Bulbasaur teaching May's along the way. Once they find Team Rocket the Bulbasaurs battle against them, with Ash's Bulbasaur protecting and teaching Mays how to fight. After rescuing the Pokémon Professor Oak calls back and asks for Ash's Bulbasaur to return and stop the water and grass Pokémon from fighting. Ash sends his Bulbasaur back to Professor Oak's Laboratory as May's Bulbasaur appears to have made a positive change from the experience.
Bulbasaur made her Contest debut in the Battle Round of the Rubello Town Pokémon Contest in Cruisin' for a Losin'. She was initially excited to participate, but became nervous when she got on stage, resulting in a loss.
In A Cacturne for the Worse, Bulbasaur was used in the Purika Contest. In the Appeals Round, she started her performance by using Razor Leaf. As the leaves were flying through the air, she whipped them with the vines from her Vine Whip attack, impressing the three judges and advancing May to the Contest Battles. There, she was seen defeating Kent's Surskit to reach the final round, where she battled against Harley's Cacturne. Their battle was a hard fought one, but in the end Bulbasaur was able to defeat the Scarecrow Pokémon with a combination of Razor Leaf and Petal Dance, giving May her fourth Hoenn Ribbon.
Bulbasaur also competed in the Battle Round of the Hoenn Grand Festival. In Rhapsody in Drew, she was called out to battle along with Beautifly against Harley's Cacturne and Banette. Together they managed to defeat their opponents and advance May to the next round.
In The Right Place and the Right Mime, Bulbasaur was shown to be one of the Pokémon May decided to bring with her when she traveled through the Kanto region. Bulbasaur was reunited with Ash's Bulbasaur when May made a stop at Professor Oak's Lab to meet up with Ash. The Bulbasaurs where later used in a battle against Team Rocket, where May's Bulbasaur was impressed by Ash's Bulbasaur's skill. May decided to leave Bulbasaur at Professor Oak's Lab so she could learn more from Ash's Bulbasaur. Eventually, after journeying to the Johto region, May got Bulbasaur back from Professor Oak, and during her time away from Ash, she evolved twice into Ivysaur and Venusaur.
She debuted as a Venusaur in Pruning a Passel of Pals!, where she defeated a Marill for May in the second battle round of the Wallace Cup. Not much is known about Venusaur since she only had a cameo appearance.
Personality and characteristics
As a Bulbasaur, she proved to be a very sweet Pokémon. She was very willing to compete in Contests and do the best she could. She was very confident in most of her Contests. The only exception was her first Contest, in which her nervousness showed in her performance.
In Grass Hysteria!, she was shown to be very protective, as she helped protect May from all of the Pokémon that tried to attack her. In Hokey Poké Balls!, she was shown to be very friendly to other Pokémon, especially Ash's Bulbasaur.
She is also very fond of flowers. She became friends with Ash's Bulbasaur when Ash temporarily brought it to Hoenn in Hokey Poké Balls! and further bonded with it in The Right Place and the Right Mime, when May decided to leave her at Professor Oak's ranch.
She was distinctive from Ash's Bulbasaur in three ways: she had a gentler personality, a pair of heart-shaped spots on her forehead and she was able to use the move Petal Dance as opposed to Ash's Bulbasaur's use of the technique Solar Beam.
It is unknown whether she still holds on to these traits after evolution.

- It is also one of the three Pokémon that appeared in the anime with a heart-shaped spot, the others being Spinda and Wooper.
- Venusaur's capture as a Bulbasaur marks the first time where one of Ash's friends acquires a species of Pokémon that Ash also had.
