Isn’t it quite obvious? Midway/DC thinks that Batman is the star in MK vs DC! Why else would he be at the forefront (and be the first one in those demo videos) of the game cover? Supes is waaaaay in the back.
Plus, why is he suddenly paired up against Scorpion? What happened to those teaser images/video? The one where he’s getting beat up by Sub-Zero?
your mind will go pi.
