Squirtle was the sixth Pokémon Ash caught. It was originally the leader of the Squirtle Squad but took a liking to Ash and decided to travel with him. Squirtle was one of Ash's most commonly used Pokémon throughout his travels in Kanto and the Orange Islands and proved to be a powerful fighter despite its small size. Squirtle is best friends with Ash's Bulbasaur and like Bulbasaur it has shown no interest in evolving despite the fact that it was certainly strong enough to have evolved. Squirtle kept the glasses it had while it was a member of the Squirtle Squad in its shell but rarely wore them.
Squirtle also battled against the Orange Islands Champion, Drake. It was squeezed by Bind, but used Hydro Pump to break free and finished it off with Skull Bash. In Enter The Dragonite, it fought Dragonite, only for its Hydro Pump to be countered by Dragonite's Water Gun. Squirtle was able to use Withdraw to endure most of the following Thunderbolt, but was still badly hurt. Squirtle used Bubble to hit Dragonite dead-on, but the attack was only half successful and it was beaten by a Slam attack from Dragonite's tail.
Shortly after their adventures in the Orange Islands, Ash asked Squirtle to go back to the Squirtle Squad to help them stop fires.
Squirtle's latest appearance was when it joined Ash's team, along with Bulbasaur and Charizard in order to battle against Pyramid King Brandon. Squirtle defeated Brandon's Ninjask with Skull Bash, but is defeated by Solrock. After the battle, Squirtle returned to the Squirtle Squad and has not been used since.
Squirtle also appears in the Adventures in Unova theme song, and also appeared in a flashback in Fires of a Red-Hot Reunion!.
Squirtle is immature, and fun loving, who's personality contrasts with its best friend, Bulbasaur, who is the serious and mature one. Despite this, Squirtle is a capable leader when it was part of the Squirtle Squad.
