The legendary Kree warrior known as Captain Marvel wielded his cosmic powers in defense of an entire galaxy...and Earth, his adopted homeworld. But in the end, he was stricken by the one enemy he could not defeat: cancer. Mar-Vell died not on the field of battle, but on a sickbed -- surrounded by an awesome assemblage of adventurers, gathered to pay tribute to the legacy of their fallen friend.

Powers: Captain Marvel could metabolize solar energy and convert it for a number of uses -- including superhuman strength, durability and flight. Though never clearly defined, his Cosmic Awareness allowed him to perceive objects, beings and galactic threats cloaked by invisibility or illusion throughout the universe.

Weapons: Captain Marvel's atom-exchanging Nega-Bands enabled him to convert psionic energy for a variety of uses -- including flight, faster-than-light travel, superhuman strength, durability enhancement and the emission of force bolts.

History: The Kree, a race of humanoid aliens, had built a galaxy-spanning empire. But the Supreme Intelligence, a fusion of past minds, was not satisfied. It encouraged breeding with other humanoid species, as the original race of blue Kree had reached its evolutionary peak. The members of the resultant subspecies, the white Kree, were biologically similar to Earthlings. But when the breeding process failed to infuse new vitality into the Kree gene pool, the Intelligence turned its attention to mankind's genetic potential. It set out to rearrange a single human's genetic structure so as to awaken in him vast psionic ability -- creating, in essence, a harbinger of human evolution. Because the Intelligence could not absorb an Earthman's mind, it planned to tie the subject's psyche to that of a white Kree. The Intelligence would form a link with the two beings, immediately gaining limitless psionic power. Then, it would use the mindless, merged entity to destroy Earth so no other alien race could exploit its inhabitants in such a manner.

Setting its grand scheme into motion, the Supreme Intelligence orchestrated a coup that resulted in the placement of a white Kree, Captain Mar-Vell, as its spy on Earth. In so doing, the Intelligence was unaware it had helped create the galaxy's greatest protector. After reporting for duty, Mar-Vell assumed the identity of Dr. Walter Lawson. As time passed, his sympathy for the people of Earth increased. Mar-Vell's partisan feelings even caused him to disobey a direct order, and he was sentenced to death. Shortly after escaping execution, he was hurled into the Negative Zone, an antimatter universe existing alongside Earth. The Supreme Intelligence telepathically enabled Mar-Vell to contact Rick Jones -- previously a companion of the Incredible Hulk, green-skinned engine of mass destruction, and Captain America, vaunted U.S. Super-Soldier. Mar-Vell's image led Rick to an abandoned Kree base on Earth. There, the exiled Kree instructed the teenager to don a pair of golden extraterrestrial bracelets. Rick slammed the Nega-Bands together with all his might...and his atoms traded places with those of Mar-Vell. The hero materialized on Earth, while Rick was surrounded by a protective aura that allowed him to survive in the Negative Zone. As long as each wore the bands, they remained in total telepathic contact. Thus, the Supreme Intelligence had created a bond between an Earthling and a white Kree.

Mar-Vell later freed Rick from the Negative Zone using a dimensional doorway created by elastic inventor Reed Richards, leader of the legendary team of adventures called the Fantastic Four. Thereafter, both beings could exist on Earth simultaneously and separately. When the warrior named Ronan seized control of the Kree government and went to war with the race of alien shapeshifters known as the Skrulls, the Supreme Intelligence contacted Rick and activated the boy's untapped psionic potential: the Destiny Force. Rick used his newfound abilities to paralyze both the Kree and Skrull empires, allowing the Intelligence to return to dominance. In return for his efforts, Rick was deactivated and lay on the brink of death. As the Intelligence had anticipated, Mar-Vell again linked himself to Rick so his life force could restore his partner.

Mar-Vell returned to Earth only to discover that Rick's body could no longer contain both beings' energies. Subsequently, Rick was bombarded with a form of electromagnetic radiation that rendered him able to contain the two life forces. Mar-Vell now found himself able to absorb solar radiation to augment his strength and fire energy bolts. A short time later, Mar-Vell became embroiled in a clash with the Eternal paramour of Death, Thanos, who planned to end all life in the universe. Mar-Vell was teleported into the presence of Eon, a galactic entity monitoring human evolution. Eon granted the hero Cosmic Awareness and designated him protector of the universe. In the wake of these changes, Mar-Vell became the primary architect of Thanos' defeat.

When Nitro, the Exploding Man, stole a powerful nerve gas, it was the strength of Mar-Vell that sealed a leak in the canister. Mar-Vell collapsed, but seemed to recover fully afterward. However, the gas had been carcinogenic. After many a heroic adventure and countless victories, the cancer-causing agent took its toll. Succumbing to an incurable systemic cancer, Mar-Vell spent his last days on Saturn's moon, Titan. He died surrounded by Rick, Earth's mightiest heroes, and various other friends and acquaintances.

Rick slowly began to move on with his life, eventually marrying. But Mar-Vell's love, Elysius, felt more alone than ever. Using Titanian science, she sampled Mar-Vell's genetic structure to conceive a child. To protect him from Captain Marvel's enemies, Genis was aged to maturity through artificial means and sequestered on an isolated world. Upon discovering his true lineage, he donned Nega-Bands similar to those worn by his father, determined to carry on Mar-Vell's heroic legacy. Eventually, he rechristened himself Captain Marvel. When Rick's Destiny powers resurfaced, he and Genis became pawns in a time-spanning conflict. At the climax of the Destiny War, Captain Marvel found himself unwillingly merged with Rick, a process that triggered his latent Cosmic Awareness.
