I gotta admit, questionable execution of DOOMED aside, the idea of Doomsday as a virus is a pretty damned cool one. Loved that "killing aura" he had going, and the idea that killing the host only releases the spores.....
I want to see that idea explored more. What if there were an entire planet infected? What if the League gets infected next time? Doomsday could be the germ warfare of the DCU......
