This Sealeo is an ice/water-type Pokémon owned by Captain Stern.
Biography[]
With his stone being stolen by Team Magma, Captain Stern sent Sealeo, who fired Aurora Beam at Tabitha's Mightyena. After sending Max and Marius to get Officer Jenny, Captain Stern had Sealeo use Aurora Beam, along with Ash's Pikachu's Thunderbolt and Corphish's Bubble Beam, which hit Team Magma's Mightyena. Stern also had Ash run off with the suitcase and had Sealeo use Blizzard. However, the plan failed, as Mightyena attacked Ash, who dropped the suitcase and a part of the stone was stolen.[1]
