|~ Captain Marvel|
The character debuted during the Silver Age of comic books and has made many appearances since then, including a self-titled series and the second volume of the Marvel Spotlight series. Captain Marvel has also been associated with Marvel merchandise including clothing, video games, toys, and trading cards.
After the Kree's first encounter with humans, Captain Mar-Vell is sent to spy on Earth and decide if it is a threat to the Kree empire. He adopts the identity of a recently deceased scientist named Walter Lawson, but occasionally dons his Kree military uniform to protect the people he's observing. The first time he does this, people hear him incorrectly pronounce his name as "Captain Marvel." His job is made difficult by his jealous Colonel Yon-Rogg, his growing affection for humanity, and his fake identity's criminal past.
After aiding humanity several times, Mar-Vell is found guilty of treason against the Kree Empire and sentenced to death by firing squad. Mar-Vell escapes in a stolen rocket, but becomes lost in space. After drifting for 112 days, he is weak and on the verge of madness. He is manipulated by Ronan the Accuser and Kree Minister Zarek into helping them overthrow the Supreme Intelligence. To better help them, Mar-Vell is given a new costume and enhanced abilities. After the conspiracy is foiled, Mar-Vell tries to return to Earth. On the way, he is hit by a blast of radiation that traps him in the Negative Zone.
The Supreme Intelligence enables Mar-Vell to telepathically contact Rick Jones, which he uses to lead Jones to a set of "nega-bands" at an abandoned Kree base. When Jones puts on the bands and strikes them together, he trades places with Mar-Vell and is encased in a protective aura in the Negative Zone. The pair discover they are able to maintain telepathic contact. Using this method, Mar-Vell can remain in the positive universe for a period of three hours.
After brief encounters with the villain Scorpio and the Hulk Jones uses Mister Fantastic's portal to the Negative Zone to free Mar-Vell, who then becomes embroiled in the Kree-Skrull War. As a result of the war, Jones was left near death and Mar-Vell re-merged with Jones in order to save his life.
Mar-Vell's consciousness began to resurface weeks later as Jones's body became unable to house both his own and Mar-Vell's life energy. Photon ray treatments by a Professor Savannah stabilized the situation and brought Mar-Vell's body and consciousness to the surface. After battling the atomic-powered Megaton, Mar-Vell is trapped in the Negative Zone once again until released by Jones via the nega-bands.
Mar-Vell aids the Avengers against the Grim Reaper and the Space Phantom. Mar-Vell allies himself with Mentor and Eros against the death worshipper Thanos and his forces in a war for the Cosmic Cube. Seeing the magnitude of the threat, the cosmic entity Kronos aids them by creating Drax the Destroyer, whose sole purpose is to kill Thanos. Another cosmic being, Eon, transforms Mar-Vell into the "Protector of the Universe." This provides the hero with new abilities, including "cosmic awareness. Thanos gains the Cube and uses it to make himself omnipotent. Thanos' spirit leaves his body, and Mar-Vell uses the opportunity to shatter the Cube, which was still in Thanos' hand. This undoes Thanos's actions.
Mar-Vell teams with Spider-Man to battle the Basilisk and later encounters a new villain named Nitro. While defusing a bomb placed by Nitro, Mar-Vell is exposed to a powerful nerve gas called "Compound 13." Mar-Vell collapses due to the exposure, but recovers when given an antidote. The gas, however, would eventually prove to be carcinogenic and cause Mar-Vell to develop cancer. Mar-Vell investigates Nitro's allies, who are revealed to be the Kree "Lunatic Legion," leading to a series of protracted battles and the eventual trial of the cosmic entity the Watcher for constant involvement in Earth's affairs. After ending the threat and aiding the Watcher, Mar-Vell briefly separates from Jones and has an encounter with a space parasite that assumes the form of former lover Una.
Mar-Vell travels to the Kree homeworld of Hala, and through a protracted series of events that almost kills Rick Jones, frees himself from the manipulation of the Supreme Intelligence. During this period Mar-Vell also encounters the cosmic entity the Stranger. Returning to Earth, Mar-Vell encounters stranded Kree scientists who attempt to retrieve an inactive Kree Sentry located on the S.H.I.E.L.D. Heli-carrier. This proves unsuccessful when the Sentry activates but fails to follow direction, going on a rampage. A new villain called the Cheetah attempts to manipulate the Sentry, although both are eventually defeated by Mar-Vell. The hero locates the Kree scientists, and briefly battles Ronan the Accuser, who was left with the mind of a child after a previous encounter.
Rick Jones is visiting Avengers Mansion when the robotic villain the Super-Adaptoid attacks. During a battle with the Avengers, Jones trades places with Mar-Vell, with the Super-Adaptoid eventually mimicking Mar-Vell's Nega-Bands. Mar-Vell then brings the Super-Adaptoid's pseudo bands together, exiling the robot to the Negative Zone and freeing Jones. Mar-Vell bids Jones farewell and encounters Mercurio the 4-D Man, who tricks Mar-Vell into returning to his home dimension, hoping to coerce the hero into building the Omni-Wave Projector. Mar-Vell, however, defeats Mercurio and returns to Earth.
Mar-Vell continues to have dealings with the Kree, preventing scientist Doctor Minerva from killing Rick Jones and battling High Council member Phae-Dor before travelling to Hala and, with King of the Inhumans Blackagar Boltagon ("Black Bolt") as his ally, preventing the "War of the Three Galaxies" by exposing a Skrull infiltrator. After another encounter with Nitro, Mar-Vell briefly attempts to adopt the Walter Lawson identity once again and works at an observatory. This plan is abandoned when forced to become Mar-Vell to stop an energy vampire named "Deathgrip." After an encounter with the Thunder God Thor, Mar-Vell is forced to fight off Drax, who has been driven insane due to being unable to fulfill his purpose and kill Thanos. Eventually convincing Drax to aid him, Mar-Vell enters into a war against ISAAC, the sentient computer that served Thanos and now directs his forces. After a series of protracted battles, Mar-Vell convinces ISAAC's female minion Elysius to join him, causing her to fall in love with Mar-Vell; he subsequently defeats ISAAC's other pawns Chaos and Tarterus and the warrior Stellarax on Earth. Mar-Vell eventually defeats ISAAC by entering the supercomputer's programming and forcing it to experience life. Mar-Vell meets Eon once again and reflects on the events of recent times.
After a battle in the mystical "Dark Dimension"; an encounter with the Hulk and an adventure on an alien world, Mar-Vell discovers that his past exposure to the "Compound 13" nerve gas gave him cancer. Compounding the problem are Mar-Vell's nega-bands, which keep the cancer at bay but also cause it to resist all known forms of treatment, and lack of access to the Kree Empire's medical experts since the Kree consider Mar-Vell a traitor. As Mar-Vell accepts that his life is ending, many of his friends and allies come to Titan to pay their last respects. Even his mortal enemies the Skrulls send an envoy to bestow a medal on Mar-Vell to honor him as their greatest foe. In his final moments, Mar-Vell experiences a vision in which he meets Thanos once again. Thanos has come not as a foe, but as a guide to show Mar-Vell the path to the afterlife. As he, Thanos, and Death pass into a blinding light, Mar-Vell dies.
His spirit was later called forth by the Grandmaster as a part of the Legion of the Unliving to battle the Avengers.
During the 2010-2011 "Chaos War" storyline, Mar-Vell and several deceased members of the Avengers return from the dead. He takes leadership of the group, helping protect several civilians and the comatose bodies of the main Avengers from chaos demons. He is impaled from behind by the Grim Reaper and is killed once more.
During the 2012 "Avengers vs. X-Men" storyline, Kree mystics appear to have resurrected Mar-Vell, using a piece of the M'Kraan Crystal in conjunction with the Phoenix Force. The resurrected Captain Marvel is deployed to act as a pawn against the Avengers and in defense of the Phoenix Force. He is shown collaborating with Ms. Marvel and Protector, announcing that they must "Destroy the Avengers". Mar-Vell, Ms. Marvel, and the Protector battle the Avengers while under mental influence. The Vision begins to free members of the Kree by countering the mind control, but the Kree are executed. The Vision then freed Mar-Vell, Ms. Marvel and the Protector from control. It turns out that Mar-Vell had a blue-skinned Kree nephew who lived in disgrace due to the Mar-Vell name being disgraced by Mar-Vell siding with Earth against the Kree long ago. This nephew was named Minister Marvel and his son had the power to influence and control minds. Minister Marvel's plan was to have the Phoenix evolve the Kree race and take credit for it thus redeeming the name Mar-Vell. Reviving Captain Mar-Vell was part of his plan as he needed a messianic figure to help rally and influence the Kree. Upon seeing his plan fail, Minister Marvel killed his son then killed himself in front of Mar-Vell. The Avengers then confront the Phoenix Force as it approaches the Kree homeworld. Thor and Ms. Marvel fail to stop it and even though Captain Britain was holding the Phoenix at bay, Mar-Vell sensed the truth of the situation. The Phoenix Force was coming to the Kree world to reclaim the Phoenix energy within Mar-Vell's body that brought him back to life and put his cancer into stasis. He sends Captain Britain away and sacrifices himself to save the Kree race that shunned him by allowing the Phoenix Force to reclaim its energies. The process left Mar-Vell adrift in space and his lifeless body was later seen on the planet with plant life suddenly growing around it. Ms. Marvel reports all this in the Avengers log and decides that the name of Captain Marvel must continue.
Powers and abilities
Upon his arrival on Earth, Mar-Vell possessed no superhuman (or super-Kree) powers apart from being stronger and more durable than most humans due to his advanced Kree physiology; the Kree have evolved with higher physical-strength levels than humans to combat the heavier gravitations of their home planets. As a soldier, the character is equipped with a device called a "universal beam" (or "uni-beam", at first a handheld pistol but later converted into a wrist-mounted device) that is capable of projecting energy; emitting beams of pure blackness and controlling magnetism.
When manipulated by "Zo" (actually Zarek , the renegade Kree Imperial Minister), Mar-Vell gained the ability to teleport to anywhere in the universe, as well as the ability to mentally project illusions. These abilities were lost when Mar-Vell gained the Nega-Bands, which convert Mar-Vell's psionic energy into greater strength, durability, and the power to fly at faster-than-light speeds and traverse vast interstellar and intergalactic distances and enable him to exist unprotected in deep outer space without having to breathe.
Once he is named the "Protector of the Universe" by Eon, Mar-Vell gains the "cosmic awareness", which (among other things) allows him to detect threats and perceive changes in the universe as long as they are important to him for some reason. This awareness can also be used internally, which alerted him to his terminal cancer even before he went to have it medically confirmed.
Captain Mar-Vell's most impressive power was his "Cosmic Awareness," which he received from Eon. This ability allowed him to know exactly what he needed to know at any moment. This could range from what his current location was to discovering an opponent´s weakness; upon acquiring this power, he first demonstrated it by realizing, not only that certain details of the special uniform with which the Supreme Intelligence had honored him for preventing its destruction had been altered, but also that Eon had transformed the color of his previously silver-white hair to blond. This power alone made Captain Mar-Vell a force to be reckoned with, but its exact nature and scope have never been clearly defined. It might have been somewhat comparable to Spider-Man's "spider-sense" and to Mantis's awareness of psychic "vibrations," but its scope was far greater than either of those.
Mar-Vell's Kree military training gives him mastery of all forms of unarmed combat and extensive knowledge of the technology of the Kree Empire.
