View source for Frontier Brain

A '''Frontier Brain''' (Japanese: '''フロンティアブレーン''' ''Frontier Brain'') is a [[Pokémon Trainer]] who presides over a certain [[Battle Frontier]] facility. Frontier Brains appear in {{v2|Emerald}}, {{v2|Platinum}}, {{v2|HeartGold and SoulSilver|s}}. Those from Hoenn hand out [[Symbol]]s 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 print]]s for the same reason.

==In the anime==
[[File:OPE09.png|thumb|250px|The Generation III Frontier Brains in the {{pkmn|anime}}]]
The Frontier Brains were first mentioned by [[Scott]] in ''[[AG132|The Scheme Team]]'' when he told {{Ash}} about the {{gdis|Battle Frontier|III}}. The first Frontier Brain, Noland, debuted in ''[[AG135|Numero Uno Articuno]]''. Over the course of [[S09|the ninth season]], the other six [[Generation III]] Frontier Brains also made their appearances at their respective facilities. Brandon reappeared in ''[[Pokémon the Series: Diamond and Pearl]]'' episodes ''[[DP128|A Pyramiding Rage!]]'' and ''[[DP129|Pillars of Friendship!]]''. Scott also inferred that they were at least at the level of the [[Elite Four]] member [[Agatha]], as both he and Agatha recommended that Ash challenge them shortly after his fight with her.

Palmer is the only [[Generation IV]] Frontier Brain to have appeared in the anime, debuting in ''[[DP140|Historical Mystery Tour!]]''. In [[DP141|the next episode]], Ash battled Palmer at the [[Twinleaf Festival]], but was defeated. Palmer also made cameo appearances in ''[[M12|Arceus and the Jewel of Life]]'' and ''[[M13|Zoroark: Master of Illusions]]''. [[Caitlin]], the employer of [[Castle Valet Darach]] who oversees all of the battles conducted at the [[Battle Castle]] in the Generation IV games, appeared in ''[[BW090|Jostling for the Junior Cup!]]'' as a member of the [[Unova]] [[Elite Four]], facing off against [[Cynthia]] in an {{wp|exhibition game|exhibition match}} at the start of the [[Pokémon World Tournament Junior Cup]].

==In the manga==
[[File:Frontier Brains Adventures.png|thumb|200px|The Hoenn Frontier Brains in the Pokémon Adventures manga]]
===In the Pokémon Adventures manga===
The Hoenn Frontier Brains were important characters in the {{chap|Emerald}}, where they were challenged by {{adv|Emerald}} in a seven-day challenge to defeat each of them at their own facilities. They also helped to fight against the armored villain named [[Guile Hideout]], who was after the {{pkmn2|Mythical}} Wish Pokémon, {{adv|Jirachi}}. They reappeared in the {{chap|Omega Ruby & Alpha Sapphire}}, helping to stop the [[Admin]]s of Neo [[Team Aqua]] and Neo [[Team Magma]].

The Sinnoh Frontier Brains appeared in the {{chap|Platinum}}, where each of them, save Palmer, were challenged by {{adv|Platinum}}. While Palmer was not battled by Platinum, he assisted the Sinnoh [[Pokédex holder]]s and the [[Stat Trainers]] in the final battle against [[Team Galactic]] in the [[Distortion World]].

===In the Pokémon Battle Frontier manga===
{{OBP|Enta|CBF}} battled each of the seven Frontier Brains in the {{gdis|Battle Frontier|III}} {{pkmn|manga}}, although his battles with Noland, Greta, and Brandon occurred off-panel. He managed to defeat six of them, but eventually tied with Anabel.

===In the Pokémon Diamond and Pearl Adventure! manga===
Palmer is the only Frontier Brain to appear in the [[Pokémon Diamond and Pearl Adventure!]] manga, debuting in ''[[DPA28|Look for Giratina!]]'', where he was encountered by [[Hareta]], [[Mitsumi]], and {{OBP|Jun|DPA}} at the [[Fight Area]].
