you have to of beaten palkia,dialga,rayquaza,groudon,kyogre and giratina and then you go to zero isle west and go to the 80th floor and look around and he will appear.
PS. You need to have mystery part in your bag
Time you can recruit Celebi and Darkness you can recruit Mewtwo
No,you can only recruit it in the Time version.
you can't... he's only on time. There aren't wonder mails or anything else
Sorry, to say, I do not think you can recruit her, though Darkrai is certainly possible. Even if you could [not sure], you'd need special parts. I think Celebi is exclusive to either time or darkness.
There is no Wonder Mail for Celebi. It can be found on Mystifying Forest 10F with the mystery part or secret slab in the treasure bag. I believe its recruit rate is around 70%, although I may be mistaken.
Yes,you can recruit heatran in giant vulcano
you can not recruit mew but you can recruit mewtwo cya later
Yes
Nope
Whatever you want. Recruiting Celebi doesn't do anything to your game, you use her as you would any other Pokemon in the game.
sadly no you can't also you cannot get shaymin
You have to complete the game, and then recruit it.
