Well, I suppose you can trick yourself into getting used to anything.

Precisely what I'm thinking, though I have no idea if Celebi would be able to affect others or if it can only move itself through time. There is a legendary Pokemon that's said to have dominion over time, but it's specific to the mythology of another region. I have no idea if it could actually be considered a universal god of time or a regional legend that's near-godlike.
