Karnak is a member of the Inhuman race, one of those who form the Inhuman Royal Family, he has the ability to find the weak point in any person, plan, or object. Thus, he is usually used as the planner by the Inhumans. He also serves as a priest and philosopher to the Inhumans.
Powers and Abilities
Karnak has enhanced strength, stamina, durability, agility, and reflexes as a result of his genetically superior Inhuman physiology. Unlike most Inhumans, he does not have superhuman powers as a result of exposure to the mutagenic Terrigen Mist, as he was never exposed to the Mist. Instead, Karnak has the extrasensory ability (achieved through meditation and intensive training) to perceive stress points, fracture planes, or weaknesses in objects or persons. He has complete voluntary control of most of his autonomic bodily functions. All striking surfaces of his body are extremely toughened. He is capable of shattering substances up to and including mild steel and rendering superhuman opponents unconscious by striking them.
He is among the Inhumans that fell under the mind-control of Maximus the Mad. In the episode "Agent Web," Karnak was with the Inhuman Royal Family when they confronted Spider-Man and Triton outside the abandoned Inhuman city of Atarog.
He is among the Inhumans that were affected by a plague that caused crystals to grow on their bodies. Karnak was seen at the end of the episode when Medusa thanked the Guardians of the Galaxy for their help on Black Bolt's behalf. In the episode "Inhuman Touch," Karnak and Gorgon help the Milano land and then they help repair it. Karnak even vowed to find Drax the Destroyer's weakspot. Karnak later helps the Guardians of the Galaxy when Maximus tricks his way out of prison.
He appears with Black Bolt, Medusa, Gorgon, and Lockjaw when an Inhuman ship carrying Seeker and the Alpha Primitives crashes into the mountains near Maple Falls. During the Avengers' fight with the Inhumans, Iron Man fought against Karnak who kept causing damages to the weak-points of Iron Man's armor.
