Frozone

In the Golden Age of superheroes, Frozone was a longtime friend of Mr. Incredible. In the beginning of the movie, shortly after interview footage, he can be seen boarding a helicopter with a hostage on board. Later, he is seen as the best man at Mr. Incredible's marriage to Elastigirl (Helen Parr).

After Mr. Incredible is sued as a result of a train wreck that occurs during his rescue of it on the day of the wedding, the supers are outlawed. Many years later, as a husband and father of three, Incredible, as Bob Parr, experiences difficulty adapting to civilian life, but Lucius does not. The two of them secretly monitor police communications and intervene on behalf of endangered people for some time, hoping to relieve Bob's tension. They are both monitored by the supervillain Syndrome through his assistant, Mirage, who spies on them. The Parrs are all captured by Syndrome on his private island, Nomanisan Island; but after they free themselves, they return to Metroville, where Syndrome unleashes an immense robotic weapon called the Omnidroid on the city. Lucius, as Frozone, along with the Parrs, manage to destroy the robot.

The Rise of the Underminer

Frozone arrives to help the Incredibles fight the evil Underminer, but after the sextet is surrounded by robots, Mr. Incredible tells the rest of the family to evacuate the city along with the rest of the citizens of Metroville . After destroying the robots, Mr. Incredible and Frozone follow Underminer underground and fight more robots along the way. When they access Underminer's main computer, they learn that he plans to use a machine called the "Magnomizer" to make the surface world feel like his home. In order to stop the Magnomizer, they have to go through the Sludge Station. After fighting more robots and hard obstacles, they destroy a machine blocking their path and apparently do the same thing to a wall which reveals a snowy underground part. They go through it and enter a room where they encounter the Magnomizer Guardian and her robot minions. Mr. Incredible throws enough objects to make the Guardian go into overdrive and destroy the room. He and Frozone escape in time and take an elevator into the Magnomizer basement. They fight more robots and work their way up, but have to avoid falling from a trap staircase that they cross, and finally reach the top of the building, where the Magnomizer is. Mr. Incredible uses his strength to unscrew the bolts that hold the machine down while Frozone fends off the guard robots. After Incredible unscrews the last bolt, the building starts to self-destruct.

Luckily, the heroes escape with a tank-like machine which falls all the way into a deep, dark pit. There, they fight more robots, whom the Crustodian, head of the Giant Robot Factory, had alerted to the heroes' presence in the factory. Finally, the two reach the apparent main office, where Crustodian is, and eventually defeat Crustodian in battle and the factory crumbles apart. Crustodian starts to leave, and Frozone tells Mr. Incredible that there is no time to destroy it (which Incredible is obsessed with doing). They leave once Crustodian disappears and take an elevator that leads to an underwater tower.

They figure out that they are in a power pressure plant run by a robot named Dug, and that the water is breaking through the crumbling plant! The two reach Dug (after battling difficult robots), who tells them that he did not intend to have the robots attack them, and he agrees to help them save some non-human scientists who are stranded somewhere else in the plant. Along the way, the heroes protect Dug from lasers, lethal obstacles, gaps and rogue robots over which Dug has no command. After all this, Dug opens the door to another elevator to allow Mr. Incredible and Frozone to rescue the scientists, but refuses to travel any further, leaving the heroes on their own.

The heroes find the scientists and save them from being exterminated by rogue robots and lasers. After the heroes take these threats down, the scientists help them return to the surface and confront The Underminer, who shows off a giant machine. But first, the heroes must first battle more robots that Underminer has for them, and after the duo defeats the robots, Underminer returns with another machine. The heroes give damage to the machine but Underminer returns to the bigger machine while the rest of the robots fall at the hands of the heroic duo. Underminer returns to give damage to the heroes who end up giving him more damage than the other way around. When Underminer returns to the smaller machine, he has run out of reinforcements and the rest of the Incredible family returns to watch as the duo defeats him, the small machine goes haywire, takes off into the air, and crashes onto the big machine, creating a large explosion which possibly slays The Underminer, and the heroes escape the blast.

Powers

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 encasing gun-wielding opponents in ice. 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 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. 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. He can also create snow, soft enough to cushion falls and slides on rough surfaces.

Equipment

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 to protect his eyes from snow blindness, and to conceal his secret identity as Lucius Best, Bob Parr's best friend in real life.
