Cyttorak

Within the provided sources Cyttorak is presented as an extra‑dimensional mystical being who was previously banished from Earth and thereafter took up residence in a realm called the Crimson Cosmos. The material frames him as a long‑lived, near‑immortal power who interacts with the Earthbound world by granting power, entering bargains, and creating worshippers and agents through his magic and artifacts.

Direct textual descriptions of Cyttorak's personal form are infrequent in the cited summaries; his portrayal in the comics includes rare in‑person appearances (first noted in a 1992 Doctor Strange issue) but he is most commonly represented through associated artifacts and magical constructs. Visual motifs tied to him include the Crimson Gem (an enchanted crimson/ruby stone) and the Crimson Bands of Cyttorak, a recurring magical restraint/construct.

Cyttorak grants great power to mortals by covenant and through artifacts, most famously via the Crimson Gem of Cyttorak which confers Juggernaut‑class strength and the power of the Crimson Bands to its bearer (the archetypal effect is to make the possessor a human juggernaut). He can create named magical constructs (the Crimson Bands), create life from magical energy (one source states he created a race of elves from magical energy), bargain with mortals and enforce covenants (granting, withdrawing, or reallocating power), and manifest familiars and avatars on Earth (examples include Cain Marko/Juggernaut, Jin Moon‑ho/Taiko, and a temporary empowerment of Piotr Rasputin/Colossus). He resides in the Crimson Cosmos, a realm where time is said not to pass, and interacts with other mystical powers in the Marvel cosmology.
