Ash's Squirtle/History/Original series/Johto

Squirtle accompanied Ash to Johto as well, the final time it would serve as a permanent member of his team. In Don't Touch That 'dile, Squirtle was used against Team Rocket with Pikachu, Bulbasaur, and Charizard. Combining its Water Gun with their attacks, it fired directly on Team Rocket's Pokémon. In The Double Trouble Header, it was sent out to battle against Team Rocket along with Bulbasaur after they captured Pikachu and. During its time with him, it and Bulbasaur showed concern for him on occasions, such as when Ash, Pikachu, and his soon to be caught Chikorita were lost in a snowstorm in The Chikorita Rescue. In Once in a Blue Moon, a Quagsire stole the GS Ball and swam away. Ash tried to run after it but ended up sending out Squirtle to chase it down. After failing to wrestle it out of the Quagsire's mouth, Squirtle used Water Gun, causing the GS Ball it slips out of Quagsire's mouth, and allowing Pikachu to catch it on the shore. While both Quagsire and Squirtle were using Water Gun against each other, Misty tried once again to catch it, but before throwing the Poké Ball, Officer Jenny stopped them and arrested them for violating the Quagsire Preservation Restrictions. In The Fire-ing Squad!, it competed in an event called the Fire and Rescue Grand Prix, a firefighting competition for water Pokémon. As luck would have it, one of the teams was the Squirtle Squad, but they were confused without their leader. Ash's Squirtle led the Squirtle Squad to win the Grand Prix, and at the end of the episode Squirtle returned to the Squirtle Squad because Ash felt that the old gang needed Squirtle more than he did. It said goodbye to its friends and Bulbasaur extended a to its long-time friend, shaking solemnly.

It returned briefly to battle in the Silver Conference after was badly injured by a group of renegade. It joined and  against the  Trainer Macy. It was Ash's last Pokémon, faced with an advantaged. However, Squirtle proved much faster and managed to hit Electabuzz with a series of Water Guns before it could launch any moves. A Skull Bash was enough to knock out Electabuzz and even up the match for Ash, leaving just left. Squirtle used an explosion of moves to cover a stealthy Water Gun, but was hit and knocked on its back by Quilava. As Macy went in for the knockout, Squirtle used Hydro Pump to hit Quilava with water and its own body, sealing the victory for Ash. Squirtle stayed around to watch Ash's Silver Conference battles, and then left in Johto Photo Finish!
