List of Frontier Brains

The Frontier Brains are a fictional group of powerful Pokémon trainers from the Battle Frontier who first appeared in the video game Pokémon Emerald. They are 7 in total, and each one resides at a Frontier facility and has his or her own title. After defeating a Frontier Brain, the trainer will receive a Silver Symbol (1st time) or Gold Symbol (2nd time). The island and the Frontier Brains are led by Scott, a talent scout for promising trainers.

In the anime, Ash Ketchum travels the land of Kanto after his journey in Hoenn, defeating the Frontier Brains. Instead of being on the Battle Frontier island, the facilities are in cities in Kanto.

In the Pocket Monsters Special manga, a mysterious boy called Emerald, who has a connection with Latias and Latios, come to the Battle Frontier island to defeat the Frontier Brains.
