Ultimate Big Chill

Ultimate Big Chill is the evolved form of Big Chill in Ben 10: Ultimate Alien. He first appeared in the episode Hit 'Em Where They Live.

Appearance
Like Big Chill, Ultimate Big Chill is a ghost-like creature with a breathy, ethereal voice, who can pass through all solid matter, go intangible, and drop the temperature of anything he chooses to just this side of absolute zero. But Ultimate Big Chill also has the ability to fire plasma energy beams that look like they are burning flames but are really pulling the heat from whatever they hit and bringing it back to Ultimate Big Chill.

Ironically, Ultimate Big Chill resembles more of a fire type alien, while regular Big Chill resembles more of an ice type alien. After evolution, Ultimate Big Chill changes his usual blue color to red. His wings and antennae now have an orange flame design. He also has a mask-like flame tuft on his face. He can still make his wings and antennae fold into a cloak, which looks no different from the old cloak, except for being red. His voice is now more gravelly, having a deeper tone behind it.

Abilities
He can still become intangible, manipulate ice, and fly. Instead of breathing ice, he can create "ice flames" (actually a heat-draining plasma beam), which he describes as "ice so cold it burns." Dwayne McDuffie described them as flames that consume the heat of whatever they touch, and use that energy to burn. He can breathe flames or shoot them from his hands, and when they hit something, it turns into blue ice. He can also freeze things faster than Big Chill. By inhaling deeply, he can lower the temperature of the air he breathes in, freezing anything that happens to be in it's path. His transparent invisible/intangible form is now red instead of blue. He is also much faster while flying and phasing through objects. Like Big Chill, he can survive in a variety of environments, including extreme heat, intense cold, deep oceans, and the vacuum of space.

Ultimate Alien
He first appeared in the episode Hit 'Em Where They Live, fighting Vulkanus and his pick-axe army. He easily froze him and his minions leading him to victory. He is Ben's third Ultimate transformation. He also appears in Escape From Aggregor to battle an innocent Galapagus. After that he appears in Ultimate Aggregor. This is the first time he is used to keep away fans. He is used again in Deep when he was trying to catch Aggregor, but he failed thanks to the piccess core guards thinking he took the map.
