"Contract."

How do you get a bunch of super-powered egomaniacs to play in your little fight games? Honestly, it's probably easier to take Grandmaster and Collector's route here, and just give them stupid crap that they want. Mind control is risky: they'll turn on you if they get free, and it also might dull their game. Hostages and threats will only get you so far, especially if you're also taking hostages and threatening the other players. Care and feeding of hostages, plus keeping track of who you threatened with what; what a hassle! The only other aspect that comes to mind would be overly competitive types, that will fight for glory and love of the game; like the Champion, or Power Princess if she doesn't stop to think about it. 

"Purgatory Island" is of course a riff on Wonder Woman's Paradise Island, although I'm not 100% sure Power Princess means it: she might allow some men, as cooks and servants and such. They may or not be castrati, depending upon how she feels at time of hire...I don't think Hyperion has ever been shown to have a Supergirl-style cousin, but we've made that joke a couple times here, as well as alluded that Power Princess does not buy that story at all. In case it's not obvious, I find the Princess fun! She would probably be around more, if she stood a little better: Sat is a much better 'actress' in these strips. Very stable, always hits her marks, rarely topples over. That said, that Satana figure is what, from 2013? I had started this plotline with maybe the idea of swapping the figure with Spider-Woman, who per OAFE.net uses the same body. Just to have a back-up plan...

Also, we finally see the 'guy' Spider-Man 2099 had been trying to get back: Spider-Hulk! One of the shrinking number of Toy Biz figures to not get a remake yet and still look good. Miguel seemed to want to rescue him pretty badly, but Pavitr seems less enthused...
