Im starting to wonder if Captain Cold and Mr. Freeze might actually be separate characters two takes on the same core theme, like Swamp Thing and Poison Ivy. It wouldnt be the first time that NRS included two ice characters in the same game.
Captain Cold
A cunning zoner who keeps the opponent at bay with ice shots, ice grenades, ice puddles, and an ice wall barrier. Hes a fairly quick and agile character.
Character Power - Captain Cold summons Heat Wave or Mirror Master. Heat Wave uses his flamethrower, which does extra damage if the opponent is frozen. Mirror Master traps the opponent in a mirror like Zod in the first game.
Super Move - Captain Cold, Heat Wave, and Mirror Master team up to attack the opponent in some crazy cinematic way.
Mr. Freeze
An in-your-face brute who uses an ice beam from a distance to freeze the opponent, allowing him to get in close and take off large chunks of health with powerful battering ram attacks and command throws. Hes a slow, clunky character like Lex Luthor.
Character Power - Mr. Freeze releases an icy mist from a chamber in his suit which lingers for a few seconds, freezing anyone it comes in contact with.
Super Move - Mr. Freeze shoots the opponents feet to trap them in place, and it begins to snow as he charges his gun, firing a massive beam for several seconds.
Of course, Freeze could just as easily be a Captain Cold alt.
