Unless i'm missing something there is no henchmen, no orbital, no sidekick, no pet. You can do literally anything with ice as they can create constructs yet there is nothing for a day 1 power? and yes i am aware Survival mode S2 had ice rewards, those are only available to the 1% sweats. I'm talking about something everyone can acquire.
The Freeze Orbital, Freeze Drone and Mr. Freeze goons were available during Survival Mode Season 2 which just ended a few weeks ago. As for sidekicks, to my knowledge, the shadow manbat and metal manbat are the only other alternative sidekick skins available.
