Nyx (Vol. 1) #8

TO SAVE THE UNIVERSE, NYX MUST KILL HER DEMONIC BROTHER!

Nyx has been trying to save her siblings from the genetic curse of their 

demonic and human sides — a curse that could cause their utter destruction! But now a crisis looms as her brother, Unison, comes into his cosmic powers and threatens to consume all of reality! Nyx must team up with her partners from the swinging ‘70s — the Vampirella and Pantha of that far-out era — to stop the end of everything. But if it comes down to it, can she kill her own brother? She’ll have to if she’s going to save the universe itself!
