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 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.
In games where the expansive Battle Frontier doesn't exist, there is usually a lone Battle Tower or an equivalent to it. In these facilities, some Trainers hold titles equivalent to Frontier Brains, such as Subway Boss, Battle Chatelaine, and Battle Legend.

In animation
The Frontier Brains were first mentioned by Scott in The Scheme Team when he told Ash about the Battle Frontier. The first Frontier Brain, Noland, debuted in Numero Uno Articuno. Over the course of the ninth season, the other six Generation III Frontier Brains also made their appearances at their respective battle facilities, which are located in Kanto in this canon. Brandon reappeared in Pokémon the Series: Diamond and Pearl episodes A Pyramiding Rage! and Pillars of Friendship! to investigate Snowpoint Temple. 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. Those who successfully defeat the Battle Frontier become Frontier Brain candidates. Ash defeated each of the seven Frontier Brains, but turned down the offer for Frontier Brain status.
Palmer is the only Generation IV Frontier Brain to have appeared in the anime, debuting in Historical Mystery Tour!. In the next episode, Ash battled Palmer at the Twinleaf Festival, but was defeated. Palmer also made cameo appearances in Arceus and the Jewel of Life and Zoroark: Master of Illusions. Caitlin, the employer of Darach who oversees all of the battles conducted at the Battle Castle in the Generation IV games, appeared in Jostling for the Junior Cup! as a member of the Unova Elite Four, facing off against Cynthia in an exhibition match at the start of the Pokémon World Tournament Junior Cup.

The Hoenn Frontier Brains were were challenged by Emerald in a seven-day challenge to defeat each of them at their own facilities during the Battle Frontier's week-long opening ceremony. They also helped to fight against the armored villain named Guile Hideout, who was after the Mythical Wish Pokémon, Jirachi.
Platinum arc
The Sinnoh Frontier Brains, except for Palmer, were challenged and defeated by Platinum at their respective facilities. Palmer, in turn, assisted the Sinnoh Pokédex holders and the Stat Trainers in the final battle against Team Galactic in the Distortion World.
At the end of the arc, Palmer reminded Platinum that his facility would be the last one to be challenged, and welcomed her upcoming challenge.

The Hoenn Frontier Brains reappeared in this arc, helping to stop the Admins of Neo Team Aqua and Neo Team Magma. They also later assisted in destroying Grand Meteor Delta.

Enta battled each of the seven Frontier Brains in the Pokémon Battle Frontier manga, although his battles with Noland, Greta, and Brandon occurred off-panel. He managed to defeat six of them, but eventually tied with Anabel.
Pokémon Diamond and Pearl Adventure!
Palmer is the only Frontier Brain to appear in the Pokémon Diamond and Pearl Adventure! manga, debuting in Look for Giratina!, where he was encountered by Hareta, Mitsumi, and Jun at the Fight Area. Hareta also had a brief battle with him when he assumed he was allied with Team Galactic, which ended in a draw.
