Frozone Halloween Costume

Frozone wields control over ice. He can create ice with his fingertips but is limited by the amount of moisture in the air and his body. He has solidified water and milk and can freeze bullets in midair while freezing opponents with weapons. As a kid, he could freeze a bowl of fruit punch simply by will power, without using his usual ice pops. He has limited air mobility, not necessarily full levitation, but he can quickly maneuver along coasters of midair icicles that lift him a good hundred or more feet in the air. He can also do big jump and air jumps. In the film, he drove through the air and hitchhiked into a helicopter. His special boots have soles that materialize into either skates, skis, or a disc - the equivalent of a snowboard. Combined with ice slides, these ensure a particularly fast ride. Also, he must wear special goggles to protect his eyes from snow blindness and to best hide his secret identity as Lucius Best, Bob Parr's best friend. It can also produce snow soft enough to cushion falls and slides on rough surfaces.
