Shadow Pony has to be the ghost of Starswirl the Bearded.

If the whole thing about the Nightmare Moon magic is true, then he'll be corrupted by it. Maybe he'll be villain of the final episode, and the Mane 6 open the box and find the Elements of Harmony replacement weapon and use it to purify him.
