Professor Elm

Professor Elm (Japanese:ウツギ博士 Dr. Utsugi) is the renowned Pokémon professor of Johto. He lives in New Bark Town with his wife and son in a house south of his laboratory (the second floor of his lab in Pokémon HeartGold and SoulSilver). Professor Elm lets you choose a Chikorita, Cyndaquil, or a Totodile as a starter Pokémon. He initially discovered that Pokémon can lay eggs. He is considered the best professor when it comes to researching Pokémon evolution.

In the games
He is the Professor of the Johto region, and is described as "a little scatter brained and disorganized" by his wife. In Platinum, a hiker in Hearthome City that in Diamond and Pearl previously gave you an egg containing Happiny, mentions him and Elm being great friends.

He is the featured professor in the Generation II games (Gold, Silver, and Crystal) and their Generation IV remakes (HeartGold and Soul Silver).
