Elm was the top student of Professor Oak, and often argues with him over their research. Elm is also well known for his very long and unnecessary speeches. He is also absent-minded and Elm has a habit of getting incredibly wrapped up in his research that he is completely oblivious to his surroundings.    Ash, Misty and Brock first met Prof. Elm in the episode Don&#039;t Touch That &#039;dile. After a period of travel, they met up again while he was studying in the Whirl Islands with Captain Marius, and finally again when Ash returns to New Bark Town.    As the head of the Pok&eacute;mon Preservation Council, he asked Ash to deliver an egg that had been poached from Mt. Silver to him.

Old Man Swamp (Japanese: ヌマタ老人 Old Numata), also known as Mr. Swampy, is the character of the day in A Mudkip Mission. Old Man Swamp is a man who runs a shelter for Mudkip and resembles the Pokémon he takes care of. He receives Mudkip eggs from the Pokémon League and raises them to be starter Pokémon for beginning trainers of the Hoenn region. When he saw that Ash and company trespassed in his secret shelter grounds, he thought that they were trying to steal the Mudkip. Soon everything was straightened out when Ash explained how Brock saved a baby Mudkip. But Brock explained to him later that another, older, Mudkip helped rescue the baby Mudkip. Old Man Swamp has a tendency of giving out too much information. One instance was him telling Team Rocket not to break the dam because it would flood the area and the Mudkip would have nowhere to live. When Old Man Swamp saw how Brock and Mudkip worked together to save the baby Mudkip and stop Team Rocket, he eventually asked him to take Mudkip with him as it was getting too old to give to a beginning trainer. Both Brock and Mudkip happily agreed.
