"Nova Against the Mighty Thor"
Chapter 2, "Fury of the Corruptor!!"
Chapter 3, "Beware the Thunder God Gone Mad!"
Chapter 4, "Fury of the Corruptor!"*
Thor, the good son of Odin assists in putting out a fire engulfing a chemical plant. Out of the smoke appears an incalculably evil entity whose very touch taints the Thunder God's soul.
Nova is still new to the Super-Hero biz, and indulges in a bit of hero-worshipping at the feet of the Asgardian Avenger. Does he ever regret that decision, as Thor hands him a lesson in immortal combat.
*The title of Chapter 4 is identical to Chapter 2, apart from one less exclamation point.
