Seel reappeared in The Misty Mermaid. During a battle with Team Rocket, Seel evolved and was able to send them blasting off. Misty's sisters were surprised by Seel's strength in battle, not knowing how powerful it was until that point.
In its debut, Seel was friendly and well-behaved, coming over whenever it was called and offering to its Trainers the Cascade Badge it was carrying on its tongue.
Later, Seel proved itself to be brave when it put itself between Jessie's Arbok and the Cerulean Gym Pokémon and Ash's Squirtle, surprising its Trainers since Seel had never showed an interest in battling before. In spite of this, Seel proved to be a formidable battler under the command of Misty, and its courage and determination gave it the power it needed to evolve into Dewgong.
