Professor Utsugi

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't Touch That '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 Pokémon Preservation Council, he asked Ash to deliver an egg that had been poached from Mt. Silver to him. This hatched into a Larvitar, which Professor Elm then asked Ash to deliver to its home.
