Arctic Colossal
Extremely feared and scarce demons from a deep, frozen pocket in the abyss, most other demons avoid them out of fear. Arctic Colossals are normally in a state of hibernation and remain so for hundreds or thousands of years, usually until they are exposed to heat (at least more than there is in their little section of the abyss.) When they awaken they are ruthless, killing without apparent motive or restraint. Eventually they slip back into hibernation, usually in the deep arctic of whatever plane of existence they stumbled or were dragged into.
In ancient times, a few foolish summoners and clerics brought the first Arctic Colossals into this world. They sought to control the beasts, which of course proved impossible. The mages who summoned them were slaughtered and their civilizations were wiped out. The Colossals would have wiped out the entire world, but instead they made their way to the arctic. There they entered hibernation, and over the hundreds of years layers of ice have built up over them, until they were completely buried. Still, the arctic cannot hold them forever, and it’s only a matter of time before the slightest disturbance wakes them again.
Arctic Colossals appearances vary greatly, but they are always bipedal and vaguely humanoid. Their individual features can rarely be seen beneath they frost that inevitably builds up on them. While there are both male and female Colossals, they do not reproduce. They were created at the beginning of time and none have been created since then.

Frost Touch: Any creature touched by an Arctic Colossal, either through a touch attack, a slam or a bite, takes 10d10 cold damage.
Freezing Death: With a successful touch attack an Arctic Colossal can attempt to freeze a creature’s completely solid. The touched creature must make a saving throw (DC 45) or be destroyed, just as though its hit points were reduced to negative ten (or whatever hit point level would destroy the creature.) This is a cold attack and only creatures that are immune to cold are immune to this effect. Creatures that succeed against the save take 10d10 cold damage.
Arctic Blast: Once per a day, as a full round action, an Arctic Colossal can release a blast of frost with a hundred foot radius. All creature within the radius take 20d10 cold damage (reflex save DC 45 for half.)
Spell-Like Abilities: 3/Day Haste, Ice Storm 1/Day Cone of Cold. All spells are cast as an 18th level cleric.
Spell Immunity: Arctic Colossals are immune to all spells that allow spell resistance, just as though the caster had failed to overcome spell resistance. Magically produced fire bypasses this immunity.
