Kaecilius is an enemy of Doctor Strange. The character, created by Stan Lee and Steve Ditko, first appeared in Strange Tales Vol. 1, #130 (March 1965).

He was a disciple of Baron Mordo who would deliver messages and even fight Strange himself if necessary. One of his first missions was kidnapping the Ancient One, which he failed at due to Strange's interference. At one point Mordo took possession of him to test the powers of Dormammu. Kaecilius was successful in stealing Strange's Cloak of Levitation, however by the end of his battle, Strange used his magic to wipe the knowledge of magic from his mind. He was last seen in Doctor Strange Vol. 2 #56 (December 1982) alongside his cohorts, Adria and Demonicus. He posed as a cameraman named Joe Crocker, but was found out along with his fellow sorcerers. They once again tried and failed to defeat the Sorcerer Supreme when Adria attempted to use a powerful gem against Strange, but banished herself, Kaecilius and Demonicus to the Purple Dimension.

Kamal el-Alaoui is a mutant villain who first appeared in Magneto #1. Kamal was amongst those Acolytes encountered by the young clone of Magneto named Joseph in the remains of the Acolytes' orbital base Avalon in the foothills of the Andes Mountain near the Bolivian border in South America. Kamal has not been seen after Cassandra Nova's Sentinel destroyed Genosha, killing 16 million mutants. Kamal's mutant powers allows him to absorb the appearance and properties of materials he touches.

Kariooq, The Corruptor appears in Alpha Flight (vol. 1) #24. He resembles a giant rotting corpse with green skin, similar to the Inhumanoid named D'Compose (although the two were created around the same time period). Kariooq is never fleshed out other than his weakness to ice ("the preserver") and his enmity with Tundra as a rival. It can be assumed however that his power might be that of decay and corruption or even control of the dead.
