It depends what levels they are
Arceus is stronger.
Arceus celebi
you dont have to defeat arceus. his only mention is as a statue.
you first catch celebi
First off, you do not catch Celebi in HG/SS. You must get it from an upcoming Nintendo Event or trade it. Second, you must get an Azure Flute from a Nintendo Event to get Arceus in Diamond. Third, the Unown have nothing to do with Celebi.
Either go to an event, or use an action replay.
Delibird Cobalion Virizon Terekkion Zekrom Reshiram Celebi Arceus And I do not know anymore.
NO! They would never battle, Celebi is a Pokemon, and Exodia is Yu-Gi-Oh. Also Celebi has a couple hundred attack. and Exodia has infinity attack.
Well, Jesus is actually the one and only Son of God. Thus, to not bring in any religious controversy into the Pokemon world, there is no Jesus because there is only One Jesus. However, on a hierarchy level, if Arceus is the god of the Pokemon, then the lesser power just below Arceus would Celebi, since Celebi brings life to all of the forests, just as Arceus brought life to all of the Pokemon.
you dont get arceus that way you get it in a wyfi event or use an action replay
None, Even Celebi isn't. Shes Psychic/Grass....
in HeartGold + SoulSilver, it is the mew event, then the celebi event, then enigma stone for latios/latias.
