Love the Freeze.
My take on a Nolan-esque origin...takes place before Batman Begins.
Victor Fries should be a thirty something, highly touted scientist who works for Wayne Inc, back when Thomas Wayne was still alive. His work should be about Cryogenics. His wife Nora is diagnosed with a fatal disease. After months of suffering she slips into a coma. Stricken with grief Victor turns to Tomas Wayne for help asking to use one of the Prototype cryrogenic chambers to preserve her until a cure can be found. Thomas declines due to financial costs. Nights later Victor returns with a new weapon, a prototype freeze gun(it looks like a crappy metal supersoaker). It shoots liquid nitrogen instant freezing it's victims. Victor steals a chamber and disappears.
I don't think freeze should be in a cryo suit. Instead a Top hat/Fedora, Trench coat, Business suit. And large round glasses with dark red lenses. And twin metal canisters on is back with a hose that attaches to a freeze gun. Rubber Mits on his hands.
He should get his name because what he does to his Victims. Completely freezing them.
Works for Black Mask to pay for his reseach.
Should be Played by.....Ed Harris.
