Shigeki Morimoto is a programmer and designer for Game Freak. He created the original battle program and all of the moves on Pokémon Red and Green and has kept on the role of Battle Director on the following games, where he redesigns and balances out the battle system in each generation. He also directed Emerald and HeartGold and SoulSilver.
Morimoto has also designed a few Pokémon in the first three generations, including Mew, which he secretly introduced in Red and Green at the end of development.
In Pokémon Black and White and Pokémon Black and White 2, he appears as a trainer in the Game Freak building in Castelia City where he will battle the player once a day. He requires the player to beat the champion before accepting the fight in Black and White and his team will change once the player does so in the sequels. He uses the Veteran sprite.
