Are there any plans for an expansion with playable versions of the villains to fight against the other villains? Like, say, a version of Citizen Dawn who isn't keen on the big cosmic entity that's supposed to be the final boss of the game?
Pretty sure the closest we're going to come is The Matriarch swapping sides... and that's in Tactics, not the card game.
It's been speculated that at least one more villain will become a playable hero.
Edit: Found where Christopher listed that https://greaterthangames.com/comment/90353#comment-90353
though in retrospect that could be referring to Pinion in Tactics and not the card game.
Well … Omnitron X, too, yeah?
And Fright Train (sort of) ;).
