Celebi is uncatchable in firered.
you really can't catch celebi in a Pokemon game without cheats
you get celebi on a gba game such as... ruby Sapphire emerald fire red leaf greenYou cannot catch Celebi in Pearl. Celebi is a Special Event accessible Pokemon only.
Its simple you cant you have to have game shark.
I don't think you can catch celebi at all in fire red. There is one way though bring your gameboy/ds with a wireless adapter to a Pokemon convention to get celebi.
you cant it is indeed impossible unless you have a gamesharkyou have to cheat or Nintendo event
its weakness includes fire, dark, ghost, flying, and ice. NOTE: celebi is a grass/phychic type.
go to where montres was on yellow and use moltres' fly in middle then use dig and she wil appear lv 5
you only can get them with cheats (i realy hate that with all that events and cheats =[ )
