Frozone (aka Lucius Best) is a male customer who first appeared Papa's Donuteria Deluxe Edition!
Frozone wields control over ice. He can generate ice from his fingertips but is limited by the amount of moisture in the air and his body. He has frozen water and milk solid and can freeze bullets in midair while congealing gun-wielding opponents. As a child, he was able to freeze a bowl of fruit punch merely through force of will, without the use of his usual ice blasts. He has limited airborne mobility, not necessarily complete levitation, but he can quickly maneuver along coasters of midair icicles (which deteriorate as he goes) which boost him in the air a good hundred or more feet. This technique is possibly inspired by Iceman. He can also take large bounds and leaps when in the air. In the movie, he skated across the air and hitchhiked onto a helicopter because of this.
His special boots have soles which materialize into either ice skates, skis, or a disc—the equivalent of a snowboard. Combined with chutes of ice, these make for particularly speedy travel. He must also wear special goggles (reminiscent of Cyclops' ruby-quartz visor) to protect his eyes from snow blindness and to best conceal his secret identity as Lucius Best, Bob Parr's best-life friend.
He can also create snow, soft enough to cushion falls and slides on rough surfaces.
