He can still become intangible, manipulate ice, and fly like his original form. Instead of breathing ice, he can create "ice flames" (actually a heat-draining plasma beam), which he describes as "fire 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 palms, 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 underwater, and the vacuum of space/
He is the third used freezing alien because Articguna in the episode Ben 10,000 was the first freezing alien used. Since it is not fast it does not take much accuracy to hit him although he may become invisible, he does not use it often making it rarely used. It is different from Big Chill because his attacking power is better because area is increased.
Like Big Chill, Ultimate Big Chill is an ethereal ghostly Mothman creature who can pass through matter. Unlike Big Chill, he is colored red. Ultimate Big Chill resembles more of an fire-type alien while Big Chill looks more a ice-type alien though both are able to go intangible, invisible, manipulate ice and fly.
