Mew, a pink, catlike legendary Pokemon, makes its home on Faraway Island. The Nintendo event that allows you to reach Faraway Island only occurs in the "Pokemon Emerald" game, so you cannot access this event in "Pokemon FireRed." If you use a Codebreaker code, though, Mew appears in the grass of the Kanto region. This gives you a chance to catch it.

About Mew

Mew made its first appearance in the 1996 games "Pokemon Red" and "Pokemon Blue." Developers intended to make Mew an unobtainable, secret Pokemon, but a coding glitch allowed players to uncover and capture it. Mew's strong psychic abilities let it learn any attack or ability, making it an ideal choice for a well-rounded, balanced team. Mew can also fly, teleport and transform into any other Pokemon type to confuse its enemies.

The Mew Codebreaker Code

Mew is normally unobtainable in "Pokemon FireRed," but a short Codebreaker code allows you to capture the creature. Insert the Codebreaker device into your Game Boy Advance. Open the "Pokemon FireRed" code entry menu. Type "000014D1 000A" on the first line and "1003DAE6 0007" on the second. On the third line, enter "83007CEE 0097." This code causes Mew to appear in the wild. If you want to set Mew's level, type "33007CF0 00XX" on the fourth line. Replace "XX" with the desired level, from 01 to 99. Activate the cheat code and start the game.

Catching Mew

When the game loads, go to the Pokemon Store and buy at least 20 Pokemon balls. Ultra balls work best for catching fast-moving Pokemon like Mew. Transfer one of your Pokemon to the PC if you want to put Mew in your party right away. Head to a grassy area and walk around. With the cheat code active, any wild Pokemon you encounter turns into Mew. Attack Mew until its health bar turns red, and then throw Pokemon balls at it. Repeat this process if you want to catch more Mews. When you finish, save your game and turn off the Codebreaker to deactivate the cheat.

Obtaining Mew via "Pokemon Emerald"

It is possible to capture Mew in "Pokemon Emerald" if you have the Old Sea Map item from a Nintendo event. Show your Old Sea Map to the S.S. Tidal captain, and he offers to take you to Faraway Island. Mew makes you chase it around the island before it battles you. After you capture Mew, you can transfer it to "Pokemon FireRed." To do this, talk to Celio on the Sevii Islands in "FireRed." Complete the quest he gives you to enable trading between games.
