Super-hero Team-Up

Nova and Firestorm always seemed like an ideal DC/Marvel cross-over. I don't know why Dr. Phosphorous came into my head, but he's one of the more visually-interesting of DC's nuke villains, and Radioactive Man, because, who doesn't like a big, scary Chinese man in an dress. Somewhere in my head, I have the distinct impression that Firestorm fought someone, once, you caused him to fission, and I thought that would be a cool visual, too. And, what better, for a 70s Super-villain team-up (as well as heroes), than a nuclear nightmare. When the bomb goes off, these two baddies will be the only guys left alive, to loot the city. Or something like that.
