Mr. Freeze

Victor Fries. aka Mr. Freeze is a common enemy of Batman and is owned by DC comics. He has a tragic past in terms that his wife has some illness. Fries put her in suspended animation until he can find a cure. But his research was interrupted and he faced an accident that turned him into an ice-based villain he is today.

Mr. Freeze maintains his body's temperature with a cybernetic environmental suit that also triples his strength to superhuman levels and is heavily armored.

Freeze's signature weapon is his "freeze gun," a ray gun that can create ice from airborne water vapor, or any nearby water source. Both the suit and gun are of Freeze's own invention, and he has developed several other pieces of technology that make him extremely dangerous.
