Doppelganger

Eversmile was a Doppelganger. A shapeshifter. When he changes, everything that isn’t the very core of his Truesoul changes with him, making him impossible to spot through any normal means. If he displays none of his power and wants to hide, nobody in the multiverse can find him… period. Even someone like Oras can’t. That is how he can be such a mystery despite having lived so long. He can be anyone at any time.
