I can get an SF grid yes but it would need to be redesced because it's originally built for a WoD vampire game and the owner who wrote all the descs considers them proprietary to her. Fair warning. It is perhaps not ideal but it is something.
Also, I would prefer working out something other than the usual 'write a gigantic app' -- again, intent prioritized over knowledge is what I want out of a superhero game. A lot of X-Men villains, even some of the big bads... are entirely playable in a demi or non-antagonistic compact with the X-Men (Sabretooth IS an X-Man RIGHT NOW, or at least allied with them, as is Mystique at least until her next Sudden yet Inevitable Betrayal) but doodz like Sinister (and I loves me some "Sinister Wilde", best version of the character ever) or Apocalypse, no. And you can even play a freakin' non-evil Apocalypse if you go with recent canon... I kinda like Genesis/Evan. He's a good kid.
