Captain Marvel  (Mar-Vell; Monica Rambeau; Genis-Vell)
   

Captain Marvel (Mar-Vell):
     Honorary member of the Avengers, deceased. 

     An alien Kree military officer whose innate pacifism and respect for humanity prompted him to desert his Kree superiors during their infiltration of Earth, Captain Mar-Vell (who was known on Earth as Captain Marvel) became a heroic adventurer on Earth, opposing the militaristic advances of the Kree and battling other menaces. 

     In later years, he gained a variety of super-powers through such sources as genetic restructuring by the Kree Supreme Intelligence, the acquisition of the nega-bands (which allowed him to absorb and manipulate solar energy for various effects), and the bestowal of "cosmic awareness" upon him by the alien Eon, who named Mar-Vell the latest in a long line of adventurers designated "Protector of the Universe.

     Mar-Vell first encountered the Avengers after he was linked to their longtime ally, Rick Jones (with whom he shared a sort of symbiotic existence for a time), and they co-operated in the defeat of the crime cartel called Zodiac. Later, Mar-Vell and the Avengers fought side-by-side during the Kree-Skrull War and joined forces several times to thwart Thanos's plans for universal conquest and interstellar genocide. By the time Mar-Vell assisted the Avengers against the would-be universe-conqueror Korvac, he was already considered an unofficial member of the team. Sadly, he never formalized his membership since he died of cancer shortly after the Korvac conflict. 

     The Avengers posthumously awarded him honorary membership in their group. Two other heroes have since employed the Captain Marvel name: longtime Avenger Monica Rambeau, later known as Photon and Pulsar; and Genis-Vell, son of the late Mar-Vell, also known as Legacy and Photon, who was recently destroyed by his Thunderbolts teammates after becoming a cosmic menace. Mar-Vell's "Protector of the Universe" role has been inherited by Avengers member Wendell Vaughn, alias Quasar.

Captain Marvel (Monica Rambeau):
First costumed alias employed by Monica Rambeau after she became a super-hero, and the name under which she joined the Avengers. 

     Dubbed Captain Marvel by the media, she used the name until a new Captain Marvel appeared: Genis, the son of the deceased alien warrior Mar-Vell (the original Captain Marvel and an honorary Avengers member). After meeting and fighting alongside Genis, Rambeau decided to let him inherit his father's Captain Marvel title, assuming the new alias of Photon instead. Later, when a transformed Genis usurped the Photon alias, Monica took the new alias Pulsar instead.

Captain Marvel (Genis-Vell):
Second costumed alias of the adventurer Genis-Vell, previously known as Legacy and later known as Photon. 

     His late father Mar-Vell had been known as Captain Marvel, and Genis gradually became known by that title as well since people associated him with his famous father; however, Genis was never fully comfortable carrying the Captain Marvel name, and eventually adopted a new alias as Photon prior to his apparent demise.
