May quickly introduced it to Pokémon Contests, where it adapted well. It was first used in the Battle Stage of the Saffron Contest, defeating Harley's Ariados, which was its first major accomplishment on May's team.
In Weekend Warrior, May was still deciding which Pokémon to use in the upcoming Silver Town Pokémon Contest. She sent out Squirtle, but she was not very satisfied with the way it came out of its Poké Ball as she needed its entrance to be flashier. Squirtle took May's comments to heart and disappeared from her sight for a little while, only to return using accessories made out of flowers in order to look more appealing and impress its Trainer.
May reassured Squirtle that it would always look cute in her eyes, and when the Silver Contest got underway, she used it in the Appeals Round. Squirtle began by using Ice Beam while spinning around and then proceeded to use Bubble, creating one large bubble surrounded by several smaller ones. After that, it jumped on the large bubble and used its Ice Beam to destroy the surrounding bubbles and used Ice Beam once more, this time aiming on the large bubble. The splash resulting from the explosion was frozen solid, creating several ice pillars and Squirtle finished by posing atop one of them. The performance impressed the judges and placed May among the four Coordinators moving on to the Contest Battles.
In Harley Rides Again, Squirtle was used in the first round of the Wisteria Contest. Its performance started with it using Rapid Spin to spin across the stage rapidly. It proceeded with a Bubble attack, making a spiral of bubbles while still spinning around. After that, it used its Ice Beam to destroy the bubbles and create a frozen fountain. It received positive reviews from allthreejudges, advancing May to the second round.
In Thinning the Hoard!, Squirtle was used in a two-on-twoContest Battle alongside May's Combusken against Drew's Absol and Flygon in the quarterfinals of the Kanto Grand Festival. Its various attacks were vital to May, the two most important aspects coming from Bubble to provide the water half of a Fire and Water combination attack and knocking Flygon out with a super-effective Ice Beam. After Flygon was defeated by Squirtle, Drew's Absol would defeat Squirtle in turn, leaving the battle to a one-on-one battle between Combusken and Absol.
In Staging a Heroes' Welcome!, Squirtle was revealed to have evolved into a Wartortle during May's travels through Johto. It was used in the Performance Stage of the Wallace Cup. Wartortle was sent out with a Foamy Seal and began by using Rapid Spin on the water field before finishing with its newly learned Aqua Tail. The performance was good enough to advance May to the next round.
Personality and characteristics
While it was a Squirtle, Wartortle demonstrated a personality that was distinct from Ash's Squirtle, as it is much younger and smaller, mainly because it was intended to be a starter Pokémon. It was also relatively shy and was a bit of a crybaby. However, as time passed, it grew considerably as it started to cry less. As a Wartortle, it's shown a more boisterous attitude with no signs of the tears that defined it as a Squirtle.
Squirtle took an instant liking to May, feeling safe with her when it got scared by Max and ran away from him in its debut episode. Also, upon witnessing May's courage and compassion during an attack from Team Rocket, Squirtle chose her to be its Trainer. Squirtle quickly adapted well to Pokémon Contests and showed a natural talent for them, with the result that May would usually use it for her Contest Appeals.
