Trivia:

Celebi was the only Pokémon of the 100 Generation II Pokémon that wasn't used in the Johto Pokérap.

Celebi is notable as the hardest to obtain Pokémon, as there are very few ways to legitimately obtain one outside Japanese games, and even there, they are only obtainable in two games.

Celebi has the most weaknesses of all Pokémon, with seven. It shares this with Exeggcute, Exeggutor, Snover and Abomasnow.

Unlike most legendaries, Celebi needs only 1,059,860 Exp. to get to level 100, whereas others need 1,250,000. It shares this trait with Mew and Shaymin.
Myths:
Myth: It is said that there are glitches in gen 3 to catch celebi?
Answer: False. There is no game data 2 support this. If anyone shows you their "glitched celebi" it was a gamesharked pokemon.

Well done (you do realise that the Gen I and II moves were the same.)
But I suppose you could get it in Crystal and trade it to your other games or is the GS ball only in Japan or at events?

can't trade between 2 and 3rd generations so nothing there, there was a celebi at the tenth aniverserary event (that's where i got mine), and he's in japan, but all celebi events R over now, and never 2 return.

At school people always used to trick people into giving them great cards for HL Dark Celebi, saying that it turned into 3000HP. This is made up, right?

idk, i know noting about the tcg, just the games.
