Trainer Tower (Japanese: トレーナータワーTrainer Tower) is a facility in Pokémon FireRed and LeafGreen located to north of Seven Island in the Sevii Islands. The area where it is located is the most northern location in Seven Island. It is similar to Battle Towers in that Trainers can be challenged in a variety of different battle types consecutively over a number of floors to reach the top; though the key concept of Trainer Tower is speed. Each battle mode has a default time and if beaten, offers a rare in-game item as a reward. Unlike Battle Towers, the player's Pokémon will not be healed between battles, though recovery items such as Revives and Potions can be used both during and between battles. If necessary, the player can return to the entrance to heal their party at the Pokémon Center, though this will waste more time in comparison to using items.
Battles conducted in Trainer Tower do not award experience or money. The level of the Pokémon used by Trainers will also match the player's highest-leveled Pokémon. Thief and Covet cannot steal items, while Trick always fails.
In the original Japanese releases of Pokémon FireRed and LeafGreen, Trainer Tower serves as a facility compatible with the e-Reader, in which cards from the Pokémon Battle e FireRed & LeafGreen set can be used to modify the Trainers the player can battle, as well as the prizes they can earn. The default layout of Trainer Tower in the Japanese versions has four floors with the same Trainers on each floor for each playthrough. Scanning cards can increase this to a maximum of eight floors with multiple combinations of opponents. The standard eight-floor layout and different battle types as featured in the localizations incorporate the majority of the Trainers from these cards.
In the Pokémon Adventures manga, Trainer Tower is a Team Rocket base, controlled by R (Japanese: ｒ), a computer created by Carr. It is equipped with 3D projectors, different sorts of weapons, and a restraint system that is almost completely immune to all kinds of Pokémon moves.
After Giovanni succeeded in trapping Mewtwo with the M2 Bind restraint armor, R came back online to explain its use and prevent Porygon2 from moving with a virtual lock. As it gloated, Giovanni noted that it was created by Carr, which explains its rude, crass, and arrogant personality. He then left the building, leaving the Pokédex holders to battle Organism No. 2's duplicates.
Eventually, Red, Blue, and Green freed Mewtwo from the M2 Bind by using theirstarterPokémon's ultimate attacks: Frenzy Plant, Blast Burn, and Hydro Cannon. Like they had planned, these powerful attacks were able to break the armor that R had claimed to be immune to any kind of Pokémon attacks, and then cancel each other out before they could reach and hurt Mewtwo. Once freed, Mewtwo used its spoon to slice the tower in two, destroying it and trapping the Deoxys Duplicates inside.
Later it was revealed that Ultima, who had come to fight Team Rocket as well, had stolen some items that the evil team had been keeping at the tower, including the Old Sea Map and an ancient manuscript about Jirachi.
