I have one for free. no cheats
Not possible. There are n events as of 2/24/12. However, you can transfer celebi via poketransfer.
It's not possible to capture Pokemon so no. You can unlock pokemon like Mew and Celebi.
You get it in 'Ollie's' last mission with the ... He asks you to catch it, but runs quickly so ride a Doduo.
you catch them
can you TRADE for a pansear on POKEMON WHITE 2!
Yes
Technically, no. You don't catch White Kyruem. You catch Kyruem and catch Reshiram. Then the two merge together.
Catch kyurem,catch reshiram, and fuse them with the dna splicers
You cannot catch Celebi in Pokémon HeartGold, the only 2 possible ways to get Celebi is via a Nintendo event or through a cheating device such as an Action Replay or Pokésav.in the trees!I don't think you can.You need an official Event, such as Gamestop's upcomong Celebi giveaway.I just don't know when it is, yet. I heard that it may be in May 2010.Celebi is not available on Pokemon SoulSilver. He is not a Pokemon that is naturally in the game, and thus, cannot be caught. Without cheating, there is no way.
Imposible.............. Possible with cheats but, you can get it in pokemon black and white 2
You cannot catch Mew or Celebi in the wild, for they are event-only Pokemon. Events for Black 2 and White 2 or previous games are no longer distributed, so an Action Replay or a GameShark will be required to encounter these Pokemon in the wild. (Do not encounter Mew in the wild in Pokemon FireRed, LeafGreen, Sapphire, Ruby, and Emerald, (Unless in Faraway Island) for it is programmed to not obey, regardless of how many Gym Badges the player earned.) Mew is an exception for 2 ways. You can perform the "Mew Glitch" in Pokemon Yellow to find it east of Lavender Town or you can have 999 Pokemon in your Pokemon Farm to get Mew from Hailey. Celebi can be found doing the "Celebi Glitch" in Pokemon Gold, but it is a lot more risky and harder than the Mew glitch mentioned above. You may want to research these glitches to get the accurate answer.
You can't
