Appendix:FireRed and LeafGreen walkthrough/Section 15

This is the Bulbapedia walkthrough for Pokémon FireRed and LeafGreen. This walkthrough follows the remade Game Boy Advance version, not Pokémon Red and Blue.
The guide for those can be found here.

Indigo Plateau

Indigo Plateau

The front room doubles as a Pokémon Center and Poké Mart, allowing Trainers to prepare themselves and their Pokémon for the gauntlet ahead. While it is possible to use items and save the game between battles, the player will not be permitted to return to the Pokémon Center unless he is defeated. In order to be well-prepared, his team should be trained to level 60 to be on equal footing with the Champion, and should include Electric-, Water-, Psychic-, and Ice-type Pokémon. Use TMs and HMs to teach moves like Ice Beam, Thunderbolt, Flamethrower, and Surf to round out the offense, and buy as many Full Restores and Revives as possible.

Take the hallway past the Poké Mart counter, and step into the first room.

Elite Four

Battle 1: Lorelei

Lorelei's room

The first member of the Elite Four is Lorelei, a master Ice-type Trainer. Three of her five Pokémon are Water/Ice types, so be wary of type-matchups. Electric and Grass attacks deal serious damage to all but her Jynx, an Ice/Psychic Pokémon that is more afraid of Fire- or Dark-type moves. Zapdos and Moltres are great candidates to use against Lorelei; Zapdos can learn the TM moves Thunderbolt and Shock Wave, while Moltres can learn Flamethrower on level 49. Keep in mind that their secondary Flying type makes Zapdos vulnerable to Ice moves, while Moltres' Fire type eliminates its weakness.

Defeating Lorelei opens the door to the second room.

Battle 2: Bruno

Bruno's room

The second member of the Elite Four is Bruno, a master Fighting-type Trainer. That being said, only three of his five Pokémon actually belong to the Fighting type. Psychic- and Flying-type moves are best against his Hitmonchan, Hitmonlee, and Machamp, but avoid using Flying Pokémon, as Hitmonchan and Machamp can fight back with Rock Tomb. A strong Water Pokémon can flood the battlefield with Surf, leaving his two Onix waterlogged. For reinforcements, consider bringing a Water/Psychic Pokémon like Slowbro or Starmie.

Defeating Bruno opens the door to the third room.

Battle 3: Agatha

Agatha's room

The third member of the Elite Four is Agatha, a master Ghost-type Trainer. Psychic-type moves deal serious damage to all five of her Pokémon, while Ghost- and Dark-type moves are also effective against her ghosts. Conversely, these spirits are immune to Normal- and Fighting-type moves under normal conditions. Ground attacks work well on Arbok, while Golbat falls to Ice and Electric moves. End the battle quickly, or risk falling victim to her Confusion- and Sleep-inducing strategy.

Defeating Agatha unlocks the door to the fourth room.

Battle 4: Lance

Lance's room

The final member of the Elite Four is Lance, a master Dragon-type Trainer, and leader of the group. The Dragon type is arguably the strongest, since it resists Electric-, Grass-, Fire-, and Water-type moves, and is only vulnerable to Dragon- and Ice-type attacks. His is a formidable opposing team, especially as they all know the devastating Hyper Beam move, though only three of the five belong to the Dragon type. Take out his two Dragonair and Dragonite with Ice Beam or Blizzard, and the bulk of his team is finished. Due to their secondary Flying type, his Gyarados and Aerodactyl are also vulnerable to Ice moves, though there are other options to defeat them. Gyarados takes massive damage from electricity, so take it down with a Thunderbolt or two. Aerodactyl is part-Rock, so it falters against Water moves like Surf. Articuno and Zapdos can be some of the best choices to use against Lance's dragons.

With the Elite Four defeated, the door to this unknown Champion's room is unlocked. Don't enter just yet, though; the player is drawn into battle immediately after exiting Lance's room, so use any items now. There is only one opponent left to defeat in order to claim the title of Champion!

Champion battle

Champion room
Hall of Fame room

The rival defeated the Elite Four before the player did, and now the title of Indigo League Champion rests with him. The first half of his team will always consist of Pidgeot, Alakazam, and Rhydon, so plan accordingly. The second half changes depending on which starter Pokémon he chose. Electric-type attacks terrorize his Pidgeot and Gyarados (or Blastoise), and a crackling Thunderbolt will send them reeling. A strong Water Pokémon can wash away his Rhydon and Arcanine (or Charizard) with Surf. His Exeggutor (or Venusaur) cannot survive long in extreme heat or cold, so a Flamethrower or Ice Beam can do the trick. The most annoying opponent may be his Alakazam with its Recover move; its Defense is fairly low, so hit it with a physical move like Earthquake.

  Player chose Bulbasaur:   Player chose Charmander:   Player chose Squirtle:

Congratulations on defeating the Elite Four and rival! The player is now Indigo League Champion! After the battle, Oak appears and leads the player past the Champion's room and into the Hall of Fame room. It is here that he and his victorious team will be recorded, as a testament to their power and perseverance. Once Oak enters the information, the game saves, and the credits roll... but the game is not over yet!
