Ego? No.
There was no ego, just a presence to mess with people like John. Ones who let their own ego dictate how others were felt. Nero never felt that. He literally just faced down something this Mage would have shit his pants before.
But that had nothing to do with their current situation, did it?
Kytana? Who the hell was that? What was he trying to do? Ha. Oh.... Well, either way, it didn't matter. Not to Nero.
"Look. John. I'm really growing tired of this back and forth. I'm not a Demon, nor Demon Prince. It's cute you think so lowly of me, it is." His voice sounded very annoyed at the accusations. "As of now, it seems I'm beyond your comprehension. You aren't in your world of Supermans, Batmans, and Wonder Womans.." Nero paused for a moment. "But, you know what? You won't believe me... Unless."
Suddenly, they were on Ganymede. One of the Moons of Jupiter, it wasn't a magic trick or anything. They were actually there. "Can you talk regularly, or do you need your magics?"
