How to Complete the Pokedex in "Pokemon FireRed"by Candice Coleman ; Updated September 22, 2017
The completion of a Pokemon Pokedex is a task undertaken in every "Pokemon" game since the original release. Players must see or collect a total of 386 Pokemon to complete the "FireRed" Pokedex. Not all 386 Pokemon can be seen or captured in "FireRed." The player must use other "Pokemon" games in the series in conjunction with "FireRed" to complete the Pokedex. Seeing or collecting some Pokemon, such as the legendary Deoxys, requires attending a Nintendo event.
Face every trainer you can find. Avoiding trainer battles can prevent you from seeing rare Pokemon that could be used to fill your Pokedex. If a trainer does not automatically challenge you when you are spotted, go up to the trainer to speak to initiate a challenge.
Trade Pokemon with friends to fill in blanks in your Pokedex. A friend who trades a Pokemon to you will not lose that Pokemon from his Pokedex. You can then trade the Pokemon back to your friend. Both of you will now have that Pokemon in your "FireRed" Pokedex.
Attend Nintendo events to acquire Pokemon. Pokemon such as the legendary Lugia and Ho-Oh can only be found after the player acquires the "Mystical Ticket" from a Nintendo event.
Level up your Pokemon to get them to evolve. Other Pokemon may require stones, which can be found or purchased, or a high happiness level, to evolve. Improve happiness by taking your Pokemon for a massage, feeding it berries it likes or keeping it in your party. Improving happiness will help Pokemon like Chansey evolve into Blissey.
Trade Pokemon to get them to evolve, and then trade again to receive your Pokemon. You must attach items to certain Pokemon when trading to get them to evolve. Seadra evolves into Kingdra, for example, when it is traded while the Dragon Scale is attached to it.
Speak to non-player characters in-game. Some will trade rare Pokemon with you in exchange for one of your Pokemon. While in Cerulean City, the player can trade Poliwhirl for Jynx.
Breed your Pokemon to fill up the "FireRed" Pokedex. Breed Clefairy and Clefable to get Cleffa or Pikachu and Raichu to get Pichu. The player can get Tyrogue by breeding Hitmonlee, Hitmonchan or Hitmontop.
Find items that will help you acquire new Pokemon. The egg Pokemon, Togepi, can be found on the Water Path. Aerodactyl, Omanyte and Kabuto can all be revived from Old Amber, Helix fossil and Dome fossil, respectively.
Trade Pokemon to "FireRed" from your other "Pokemon" games, such as "Ruby," "Sapphire," "Emerald" and "LeafGreen." You must first get the Pokedex in "FireRed" and fix Celio's Network Machine, located on One Island of the Sevii Islands in the Kanto region to trade. Connect two Game Boy Advance systems using a Game Boy Advance link cable. Insert "FireRed" into one system and the other "Pokemon" game into the other. Trade your Pokemon at any Pokemon Center.
