I've been reading up on these Death Spores, and on Omega Red in general. As far as I can tell the spores aren't the insta-kill, cr@p-your-pants weapon they are usually made out to be on these pages. Seems that normal, ordinary humans drop like flies, sure, but metahumans should have a pretty good resistance at least for a short while. Add to that the fact that OR has been taken down by characters like Nightcrawler, who in my opinion would get used as a pitbull's chewtoy by Midnighter, and I think there is a good case for Midnighter.
I am now going to go and search the Respect forum for 'Omega Red', where I am 100% confident I will find a deluge of facts that will utterly demolish what I have just said! Hahaha!
