Chaletwo: You sound like Mew. I'm not resigning myself to it just because it might be fate or the will of nature or whatever. We can still fight it, and even if it's impossible to prevent it, we're no worse off having tried.
Molzapart: Well, yes. That's just a theory. It might also be possible to stop it, and so we try. Why shouldn't we?
Mew: Why do you ask me? I am not trying to stop it.
Chaletwo: Deoxys is a pokémon that was created when a space virus was exposed to a laser beam, rather than being created by Mew. As such, is it still susceptible to the drain brought about by the destroyer?
If so, have you considered the possibility of another legendary being created in a similar way without your knowledge?
Chaletwo to zeKieranator: No way. Mew is the Creator, and if he were the Destroyer he'd hardly have told us the War was starting again, much less the Beasts, would he?
Chaletwo to Ramenlord: Deoxys is affected. We don't know why. There could theoretically be more legendaries existing without our knowledge whether they're affected by the Destroyer or not, but we have to hope that someone would have noticed them by now.
Hm, I'm interested in the whole 'True Immortal' thing. Chaletwo: What would happen if you were dropped in a vat of acid or lava or something? That should destroy the body, but being a True Immortal… EDIT: Or what about if you were poisoned, or crushed?
