Trolling Creator: Marvel Comics at first, but the writer picked up the slack quickly. His phrase "I want them all to be Katniss" lives in infamy. Also, Hopeless went out of his way to emphasis that Nico was really dead...turns out (at least in Nico's) case Death Is Cheap.
Writer Dennis Hopeless said that he wanted all the Runaways along with some kids from the Jean Grey school for the book as well, however due to the already large size of the cast he backed off. Also, he wanted to use Kenji/Zero from Generation Hope so he attempted to either reverse the decision of killing him off or revive him in Arena (and then kill him again), both options were rejected. And before all that? This was just going to be an arc for a proposed Braddock Academy series.
Hopeless later stated this was actually for a proposed series about school created by SHIELD, and that the editor basically ignored everything else in said pitch except for a storyline about a sort of tournament between different superhero schools that got turned into a death match.
