Will Arceus (in Platinum) have a certain nature?

Question

In Platinum, my Dialga had Adamant nature (+Atk, -Sp. Atk), and my Palkia had Modest nature (+Sp. Atk, -Atk). I don't think that it's a coincidence. Will Arceus have a specific nature?

Answer 1

You can't get Arceus anymore since its event has passed (unless you hack).

Most Pokemon do not have a present nature, legendaries included; exceptions would be N's Pokemon. You just got lucky and got a Modest Palkia (I wouldn't say that Adamant was the preferred nature for Dialga).

I'm talking about Arceus in the Hall of Origin. (Platinum)

No. Even if you did manage to get the Arceus there, it won't have a set nature.
