Sombra is Alter's spirit partner, come to life after Alter turned Five, like everyone on his planet. He is connected to Alter's desires, so anything Alter deeply wants, he himself wants. Though he does have some of his own, they can sometimes override Alters.

He's made completely of shadows, but can be solid at will. He has a sarcastic personality and tries to be serious, but sometimes just falls into a goofy mood. He mostly just follows Alter around and snarks on things he does, but he'll jump in the action if he needs to. When not doing that he'll be seen hanging around other small cute creatures doing cute things.
