Well that does raise a good point, and there is no simple answer. A duplicate of the void wouldn't even be sentient or as dangerous. Considering he makes a shadow of the ability. It looks the same but at its core really isnt.

I suppose the real problem emerges from the Antireen control. Since his power is that of a god sealed in a mortal form, only allowed a vague semblance to actual power by copying the powers of others. He would either be able to use it until he used up the power itseld, or it would be incredibly useful. Using the latent power within him.

Benny is a hard character to regulate, since he was intended as a raid boss styled big bad, rather than a  final boss sort.
