Kamran is a young Pakistani American who discovers his Inhuman heritage after being exposed to the Terrigen Mists which grants him bio-luminescent abilities. After moving from Houston to Jersey City, Kamran is reintroduced to Kamala Khan whose parents are friends with his, and the two quickly bond over their shared interests. After witnessing Kamala change into her alter ego, Ms. Marvel, Kamran reveals his secret to her, which makes her smitten with him.^[1] Kamran offers Kamala a ride to school, but instead of taking her to school, he kidnaps her and takes her to his boss, the Inhuman crime boss Lineage who hopes to recruit Ms. Marvel into his gang.^[2] Ms. Marvel fights off Kamran and Lineage and escape from them.^[3] Desperate to prove himself to Lineage, Kamran kidnaps Kamala's brother Aamir and exposes him to stolen Terrigen Mists which awaken Aamir's Inhuman powers.^[4] Aamir doesn't go into a cocoon as those exposed to the Mists usually do, yet despite this, Aamir gains the ability to generate psychic force fields which he uses to overpower Kamran.^[5]

Sometime later, Kamran approaches Ms. Marvel, apologizing for his actions, and attempts to reconcile with her. They are interrupted by Shang-Chi, who reveals that Kamran had stolen the mystical Eyes of the Dragon from the Five Weapons Society and was planning on using them to steal Ms. Marvel's life force to empower Lineage.

He then used Storm (Marvel Comics) as a focal point for magic and life itself to give life to the barren land of the Autumn Continent.^[9]

During the hunt against Master Weaver, he hesitates to deliver the finishing blow, leading to the death of his mother. As a result, he is condemned to wear a mask by his father Solus, and exiled to hunt Spider Totems to earn his place back in the family.^[11]

The time-displaced Superior Spider-Man (Otto Octavius's mind in Peter Parker's body) later discovered Karn. Assembling an army of Spider-Men, the Superior Spider-Man and his team ambushed Karn while hunting the Spider-Man of Earth-2818, but despite Karn continuing to gain the upper hand, the Spider-Men only escaped when two of Karn's estranged siblings showed up and began fighting.^[11] Karn later joins the Spider-Men in their fight against the Inheritors.^[12]

Karn realizes that Master Weaver is his future self. He establishes a new team of multiversal spider-heroes called the Warriors of the Great Web, consisting of Mayday Parker, Spider-Ham, Spider-Man Noir, Spider-Man India, and Spider-Gwen.

During the "Electroverse saga", an alliance of counterparts of Max Dillon invades Loomworld, damaging the great web while forcing the Web-Warriors to retreat to Earth-803. Karn and an alternate version of Doctor Octopus managed to fix the Web, but tangle it at the same time, causing the Web Warriors to become split between realities. Karn's reconnection of Earth-803 into the web also causes an earthquake that frees the Electros caught by the Web-Warriors.^[13]

During the Dead No More: The Clone Conspiracy storyline, Karn welcomes Kaine Parker, but soon realizes that he no longer has the powers of the Other and is now dying from a Carrion virus, and cannot go back to his Earth lest someone catch it. Karn shows Kaine many realities with zombie apocalypses caused by this disease, and Kaine decides to visit these realities to find a way to stop it. Kaine tries to keep himself hidden from the Web Warriors while researching, but is caught by Spider-Gwen.^[14]

During the "Spider-Geddon" storyline, each of the Spider-Men and Master Weaver has been keeping an eye on Earth-3145 by sending different Spider-Bots to check on them, discovering that while alive, the Inheritors have gotten malnourished from lack of spider life-forces. Unknown to the Spider-Men and apparently to Master Weaver himself, the Inheritors are collecting the heads of the Spider-Bots with Jennix stating that they now have the resources they need.^[15] When Spider-UK and Master Weaver get alerted to an Inheritor Cloning Engine on Earth-616, the two of them figure out what is happening. On Earth-3145, Jennix has put the Spider-Bot heads to good use by harvesting their transmitters. As they are unable to send a kill signal to the Inheritor Cloning Engine, Spider-UK advises Master Weaver to call the Web Warriors. When Master Weaver states that nobody can fight the Inheritors and win, Spider-UK states that they'll die trying to keep another world from being destroyed.^[16] Karn is then confronted by Verna for having sided with the Web Warriors as they fight to the death. After Karn stabs Verna, she still feeds on him as he is now a Spider-Totem.^[17] When Karn's dead body is found by Spider-Nor-Man, it is devoured by Spiders-Man of Earth-11580.^[18]

Like the rest of the Inheritors, Karn can drain the life force from other beings through physical contact. Depending on the power of the individual he drains, his powers and vitality can increase substantially. He also has superhuman strength, speed, reflexes, and durability. He has a staff that emits a unique energy signature capable of vaporizing people.^{[volume & issue needed]}

Created by	Roy Thomas (Writer) Marie Severin (Artist)

Karthon the Quester is a fictional character appearing in American comic books published by Marvel Comics.

Karthon is a member of the scaly-skinned subspecies of Homo mermanus called Lemurians. He served Naga as the foremost of his "Questers", searching on behalf of the undersea kingdom of Lemuria to retrieve the legendary Serpent Crown, which had been lost beneath the sea by Paul Destine. Namor found the Crown at the same time as Karthon.^[66] The two fought over the Serpent Crown. Karthon told Namor that the Crown would allow the Lemurians to conquer the world, but Namor revealed to Karthon that the Crown was actually a vessel empowered by the demonic Elder God Set. As the two fought, Captain Barracuda and his crew inadvertently captured them in an electrified net. Namor broke free and fought Barracuda's forces, while Karthon took the Serpent Crown and fled back towards Lemuria.^[67]

Namor managed to catch up with Karthon and the two continued to fight over it until Karthon subdued Namor and subverted his will. The two traveled to Lemuria, where Karthon returned the Serpent Crown to Naga. Naga ordered Namor's death, and when Karthon refused to murder him, Naga struck Karthon down using the Serpent Crown and sent the other Questers to attack Namor. Namor collapsed the royal chamber over Naga's throne.^[68] Karthon tried to hold back the vengeful Namor, who tossed both Karthon and the other Questers aside. Karthon asked Naga to stay his hand against Namor, and Naga instead obliterated the other Questers. The despondent Karthon asked Naga to destroy him as well, but Naga wished to keep Karthon as his enforcer. When Naga caused the death of Karthon's sister Llyna, Karthon became enraged by this final betrayal and slew Naga from behind with his sword. Karthon nearly fell to the evil call of the Serpent Crown, but Namor placed the Crown on Naga's corpse, which was then pulled into a great fissure which opened in the ocean floor.^[69] The Lemurians proclaimed Karthon their new king, and he accepted, vowing to end Lemuria's history of despotic rulers. Karthon's rule is wise and just, and the Lemurians became allies of the Atlanteans.^[69] Llyra, the High Priestess of Set, managed to subdue Karthon and usurp the leadership of Lemuria for herself. When Namor tried to recruit Karthon and his nation as allies of Atlantis, he found Llyra ruling the city. Namor defeated Llyra and returned Karthon to the throne.^[70]

Using his influence on her, the Skull is able to convince her of Hydra being a noble organization. Kobik later makes contact with the elderly Steve Rogers during a stand-off where his life is in danger, and as a consequence of the Skull's manipulation, she not only reverts him to his youthful state but also rewrites his history so that he has been a Hydra sleeper agent since childhood. As Hydra's "Secret Empire" rises to power in the United States, Kobik begins to regretfully rewrite Rogers' mind, but it is revealed that the memory of his original, good conscious has remained hidden in her mind. The original Steve Rogers tries to convince Kobik to undo her mistakes, but she believes it is too late and is frightened of Hydra Rogers. Making things worse, in the real world Arnim Zola implants a Cosmic Cube into Rogers' physical body during the Resistance's hopeful raid on Hydra's main base, led by Sam Wilson. However, the good Rogers manages to get through to her, and eventually, they are both saved by Bucky Barnes and Scott Lang, who takes away Hydra Rogers’ ability to use both the Cosmic Cube and Mjolnir, allowing the real Captain America to defeat his mind-altered self.

An elite assassin and member of the terrorist organization Hydra, he also used the name and debuted in Secret Warriors #2 (March 2009). Writer/artist Jonathan Hickman stated in an interview with Comic Book Resources that "Kraken" is a new character. The other Hydra character with that name [Commander Kraken] was "a real b-list character and pretty lame. Our Kraken... has a long and elaborate history and we're going to be delving into that in a major way".^[144] Kraken is a legendary Hydra agent, whose existence had been unverifiable, until recently. Any S.H.I.E.L.D. agents that tried to find documented proof all disappeared. The Kraken preferred to work behind the scenes, seeing it as his mission to help people become what they are meant to be, usually with dangerous results. For decades, he was responsible for developing Hydra's best assets, training their best talent. This involved a lot of human trafficking, theft, and murder. He was the head of the school that trained orphaned girls (including Ophelia Sarkissian) into human weapons. The original Kraken is Whitehall, but a second version stole his equipment and read his journals.^[145]

It is revealed that this second version is actually Jake Fury having infiltrated Hydra's highest rungs to help Nick Fury bring about its destruction.^[146]

A new Kraken is seen when the new Madame Hydra is collecting members for the HYDRA High Council to assist Captain America, whose history had been altered by the Red Skull's clone using the powers of Kobik to include him always being a member of HYDRA.

Kurse is the name of two fictional characters appearing in American comic books published by Marvel Comics.

Kurse was originally the most powerful of a race of Dark Elves and known as Algrim the Strong^[173] He is coerced by the Dark Elf ruler Malekith the Accursed to fight the Asgardian God of Thunder and superhero, Thor. Malekith, however, betrays Algrim while he is fighting Thor, and in a bid to destroy the Thunder God orders that a pitfall beneath the two be opened. Thor saves himself courtesy of his mystical hammer Mjolnir, while Algrim falls into lava. Algrim's enchanted armor saves his life, but he is critically injured and develops amnesia from the shock, and is left with an obsessive desire for revenge.^[174]

Algrim is later healed by the cosmic entity the Beyonder, who transforms him into the much more powerful being called Kurse. The Beyonder transports Kurse to Earth to battle Thor, but Kurse mistakes Thor's ally Beta Ray Bill for Thor and battles him.^[175] Kurse then battles the juvenile superhero team Power Pack.^[176] Thor dons his magical belt of strength to double his strength and confronts Kurse, but the Beyonder doubles Kurse's strength as well. With the assistance of Power Pack, Thor and Bill are able to overcome Kurse, and Thor helps him remember that it was Malekith, not Thor, who is to blame for his suffering.^[177] The Beyonder then transports Kurse to Hel at Thor's suggestion, to frustrate Hela, the Goddess of Death.^[178]

Kurse later confronts and severely beats Loki, who had been disguised as Malekith. Drawing off, he leaves Loki injured and finds someone who seems to be Balder the Brave, surrounded by legions of Asgardians. He barrels through them and slays his target, who turns out to be the true Malekith. After repenting, he is granted citizenship among the Asgardians.^[179]

He is designated as the guardian of the children of Asgard after helping to protect Volstagg's daughter and adopted sons during a plague,^[180] and loyally serves Asgard until the time of Ragnarok. At the time of Ragnarok, all the Asgardians apparently perish, with the exception of Thor.^[181]

Kurse is later captured by Malekith, who strips him of the armor. Algrim is sent to Nastrond Prison where he is forced to serve out the rest of the sentence of Wazaria, a former member of the League of Realms. Malekith forces Wazaria to don the armor, transforming her into the new Kurse. Before he is imprisoned, Algrim encourages his successor to kill herself the first chance she gets.^[182]

Waziria is a Dark Elf witch of the Dove Gut Tribe in Svartalfheim.^[183]

When the League of Realms split, only Waziria remained with Thor. During a meeting with the Dark Elf ruling council called the Council of the Unhallowed, Thor accused Waziria of being the traitor and that she gave Malekith the information to stay one step ahead of him, only for both to learn that it was Thor himself who had been bugged. Malekith then makes himself known.^[183] Before Malekith can kill Thor, the League of Realms showed up to help fight Malekith. The Council of the Unhallowed made the decision to side with Malekith. When the Congress of the Worlds planned to have Malekith rule Svartalfheim after he is done with his life sentence in Nastrond Prison, Malekith made Waziria his proxy while Malekith named Scumtongue his senator for the Congress of the Worlds.^[186]

Even though they outscored Thor, thanks to their disposition to cause mass suffering in order complete certain tasks, the challenge's officiate Shadrak declared Thor as the winner, since she inspired the Asgardians gods to help her in defense.^[201] Infuriated, they called upon "their sister" the Phoenix Force to destroy all reality, but with the help of Quentin Quire, Thor and the Asgardians appeased the Phoenix Force. Sharra and K'ythri were then imprisoned in Omnipotence City, since they had broken the divine law.^[201]
