From Bulbapedia, the community-driven Pokémon encyclopedia.
Marius (Japanese: ヨウスケ Yōsuke) is the character of the day in The Spheal of Approval.
Marius made himself the self-appointed security guard of the Oceanic Museum. Spotting Max trying to climb the wall of the closed museum, he assumed that Ash and Max were trying to break inside because they were thieves. At this, Marius sent out his Spheal to attack them, not listening to their repeated denials. Fortunately for Ash and Max, but unfortunately for Marius, Spheal wasn't interested in battling and only wanted to play. When it finally listened to what Marius said and attacked, it got hit by Pikachu's Thunderbolt. Marius was shocked, unable to believe that it was possible for a Pikachu to defeat Spheal. Max went on to explain that Water types are weak against Electric-type moves.
Soon Captain Stern entered the scene and Marius promptly told him that Ash and Max were thieves. Max then explained that he just wanted to see the museum. After dealing with the misunderstanding, Captain Stern invited them all in to see the museum.
Marius displayed his lack of knowledge about Pokémon whilst in the museum. He said he wanted to catch a Goldeen so that he could "evolve it to Gyarados". Max then corrected him saying that only Magikarp evolve into Gyarados. Marius also dreamed about traveling around the world by sea inside the submarine that the captain was building.
Soon he, Ash, and Max were captured by Team Rocket, and then they come to find out that Team Magma stole the meteorite that Captain Stern was going to study. Marius tried to use his Spheal to save them, but Spheal refused to listen to him.
After they chased down Team Magma, Captain Stern told Marius and Max to go back to town to get Officer Jenny. They were able to get there in very little time because of Spheal's incredible speed in the water. Later on, they found out that Team Magma got away with the meteorite. Thankfully, Captain Stern did have a small piece of it left that broke off during the battle. Once the danger had passed, Marius informed Ash of his desire to have a rematch the next time they met.
| Spheal is Marius's only known Pokémon, sent out by Marius to deal with Ash and Max when he assumed that they were thieves. Ash used his Pikachu to battle Spheal. However, Spheal spent much of its time clapping rather than battling and was defeated easily. Later, Spheal repeated this behavior while Marius, Ash, and Max were stuck in Team Rocket's cage. Spheal was shown to be adept at traversing large bodies of water at very high speeds when it swam Max and Marius to the shore opposite the Oceanic Museum.
Spheal's known moves are Body Slam, Water Gun and Blizzard.

- Marius has a striking resemblance to the Bug Catcher Trainer class in the games. Despite this, he does not own any Bug-type Pokémon.
- He shares his name with another character in the anime: Captain Marius. Similarly, this Marius makes the impression that he is striving to become a sea captain.
