I'm wrote a story about an anti-God who existed before the creation of the multiverse, and he exists within the primordial void of creation and existed with perfect unity.

Until the monotheistic Supreme being made the omniverse and brought creation into existence, because of this he begins to fill with rage and wages a outerversal war against him and creates an infinite army of beings called void soldiers, and he falls into the lower and darkest parts of the omniverses and his army gets thrown into a super-void .

The anti-God is not dead nor defeated and now decides to consume and begain he full power back to kill the monotheistic Supreme being.

So this is what I have but the problem is I don't know what powers to give him and if anyone has suggestions let me know and I will pick them .
