Besides trading, you can't
cheat
you cant it is indeed impossible unless you have a gamesharkyou have to cheat or Nintendo event
The only legitimate way to obtain Celebi and Mew is through a Nintendo event. In FireRed and LeafGreen you will need an event-only item to travel to the last two islands where you can catch those Pokemon
Without a cheat, Celebi isn't available in the games. You have to get it from a Nintendo Event
you need a gs ball
You cant get him. I think its only through an event.
Celebi cannot be found in the wild in Pokemon SoulSilver. Celebi is an event Pokemon, and can only be obtained through the event. You will have to trade for it or cheat for it to get it.
You cant unless you go to an event or cheat
You can't obtain Celebi without an event or a gameshark. Don't listen to the people who tell you that you can get it without cheats.
You cant unless you cheat or an event.
celebi was a gamestop event that has now blown over. now to get it, you must cheat or trade.
Unfortunately it's not currently possible to get Celebi since Pokemon hasn't given him out since I believe the 10th Anniversary event if I recall correctly. So currently the only way to get Celebi is by trading.
