Somewhere along the mid-2000's, someone at Marvel decided that the company should do a space-themed event series. It would include almost all of the companies cosmic heavy hitters. Popular characters like Galactus, Silver Surfer and Thanos showed up on it, but there was also some oddball choices and C-list characters.
One of them was Nova, also known as Richard Rider, who had his last solo series years ago and was in the popular-at-the-time New Warriors, but not much else. Under the dexterous hands of Keith Giffen and the duo of Dan Abnett and Andy Lanning, in the pages of Annihilation and later his most recent solo series, Nova flourished into a much more interesting character: a seasoned war horse that left his wide-eyed days in the past, but with a sense of humor nonetheless. His rise in status is perhaps summed up best by the time he ripped out Annihilus entrails from the inside, effectively ending a threat that killed millions of beings in the universe.
Nova went on to live a long and productive life as a space cop. That is, until (Spoilers from years ago) Richard died. A new one has recently showed up, but he is going to be written one by Jeph Loeb, so perhaps the dead one is better off.
So, in short, expect to see many space adventures, explosions, and "Blue Blazes!" this week.
