to my knowledge you can't. Legendaries are one of a kind so you can't duplicate them.
Celebi: You don't. Gible: Breed any of the Garchomp line.

are you asking if you breed them? well they won't have eggs. none of the legendary Pokemon can't be breeded.
You get it by corrupting your game with cheats. (GameShark etc...)
Arceus was a lone egg in chaos. He hatched. He created Dialga, Palkia, and Giratina then made Mesprit, Uxie, and Azelf then went to sleep. Mesprit, Uxie, and Azelf made Mew and the humans. Mew made Pokemon.
