No, my character is not God.
It's my take on the Spectre.
Yolu can either think he is a sort of Angel of Vengeance, that actually relates with God, or just a guys obsessed with the Bible that, once powered up, believes himself to be that.
In any case, I will try today to flesh him more, to help every writer to understand him. Ah, he talks only with citations of the Bible, so, either do your homework, or don't have him speaking.
As for his "role", I see him like Hulk in the first issues of the Avenger. I think he could be seen as a menace or a powerful force to be "used" by the good guy.
He could seems too much powerful, but I think he could be used like Mxy in Vanguard, where his omnipotence was limited effectively by his wackytude. For Emmanuel, I guess moral dilemmas could be what costrain him.
