Frontier Brain

A Frontier Brain (Japanese: フロンティアブレーン) is a Pokémon Trainer who presides over a certain Battle Frontier facility. Frontier Brains appear in Emerald, Platinum, HeartGold and SoulSilver. Those from Hoenn hand out Symbols to Trainers who rise through the ranks and show true skill in each of the facilities, while those from Sinnoh and Johto hand out commemorative prints for the same reason.

Trivia

• The original Japanese name of every Frontier Brain is derived from a flower, tree, fruit, or other plant. The same naming convention also applies to Gym Leaders, as well as the Champions and members of the Elite Four, with the exceptions of Blue and Cheren, who were not Gym Leaders or Champions in their original appearances.
• The title of "Frontier Brain" was given to the top performers in the Pokémon Emerald Ultimate Frontier Brain Battle.
