Monica Rambeau was born and raised in New Orleans, Louisiana. She enlisted into her local police department and quickly rose through the ranks, positioning herself as lieutenant of its Harbor division. While off-duty, she helped a scientist track down an international dictator, who wanted to use a powerful energy machine to take over the United States. After thwarting his plans, she attempted to destroy the machine and was bombarded by extra-dimensional energy. As a result, she gained the ability to turn into any form of energy along the electromagnetic spectrum and discharge it.
Monica Rambeau was created by Roger Stern and John Romita, Jr. Her first comic appearance was in the Amazing Spider-Man Annual #16 (1982).
Mayor Story Arcs
Monica was dubbed Captain Marvel by the media after gaining her abilities, and using them to fight crime. It was a name she happily utilize and embraced. After experimenting with her powers, she realized that her abilities were growing out of control, so she ventured to New York, in search of Reed Richards. Instead of meeting Richards, she met Spider-Man, who introduced her to the Avengers. Iron Man was able to assist her by using his power-suit to stabilize her fluctuating energy levels.
Afterwards, she hung around and eventually became an Avenger. Monica served a lengthy stint with the Avengers and routinely became the team's leader. While attempting to save Marina Smallwood from mutating into a leviathan, she inadvertently crippled herself by exerting too much of her energy.
Her powers were greatly depleted and she was forced to retire afterwards. Monica's energy levels gradually returned to her, and she later rekindled her connection to the Avengers, briefly leading them a few more times before becoming a reserve member.
Monica operated as Captain Marvel for most of her Avengers career. However, when Genis-Vell (son of the original Captain Marvel) joined the Avengers, he began calling himself "Captain Marvel." Monica was initially put off by him doing so and he attempted to concede the name back to her. However, she refused and allowed him to continue utilizing the name out of respect for his father. Monica then began calling herself "Photon."
After willingly giving up her title as Captain Marvel to Genis-Vell out of respect for his father, Monica was angered upon learning that Genis changed his name again, this time to "Photon." After confronting him about his actions, she decided to allow him to have the name and began contemplating the uses of the alias, "Pulsar."
Agent of H.A.T.E.
After several sporadic adventures with the Avengers, Monica eventually dropped the code-name "Pulsar" and began to simply address herself as, Monica Rambeau. She becomes an agent of the Highest Anti-Terrorism Effort (H.A.T.E.) squad called "Nextwave," formed to fight the "Unusual Weapons of Mass Destruction." Members other than herself included, The Captain, Boom Boom, Machine Man, and Elsa Bloodstone. Monica was a valuable asset to the team, yet annoyed all of her teammates by constantly bringing up her past experience leading the Avengers, and she developed a penchant for shouting the names of her energy attacks.
She had several adventures separate of Nextwave assignments, but still remained as an active team member. Monica joined Blade, Black Panther, Luke Cage and Brother Voodoo (who she began to date) in her hometown, New Orleans, to fend off a growing vampire cult. Her ability to utilize light energy allowed her to dispose of the vampires with little effort. During the events of Civil War, Monica was recruited by Captain America to become a member of his Secret Avengers. Later, she traveled to hell with her friends, Black Cat and Firestar, to save Hellcat from her ex-husband, Hellstorm. At one point, Brother Voodoo became "Sorcerer Supreme," and it was reveled that Monica's relationship with him had gone sour. The two would develop an on-and-off-again relationship, until his apparent death.
Sometime later, Monica teamed up with Carol Danvers, after recruiting her to assist in an investigation of a large mass of crashed ships and planes found around New Orleans. It turned out that the crashed ships had been pulled to the same locations by a large force of robots, created by a long dead villain. The robots merged together, which required Monica and Carol's combined power to defeat it.
During the events of Infinity, the Avengers left earth to confront and prevent the Builders from destroying all life in the galaxy. While the Avengers were off-planet, the mad titan Thanos decided to invade Earth. Prior to his invasion, Monica traveled to New York to "test drive" a new costume. While on patrol, she stopped a bank robbery committed by the Blue Streak. When she handed him over to the authorities they addressed her as "Spectrum," a new alias Monica is now calling herself.
After returning to the costume shop, she encountered Blade, who apparently could not be seen in country. Although he was not supposed to be stateside, he wanted her help (presumably to kill vampires again). When Blade recruited Monica to fight vampires years ago, she was not too fond of him. She is somewhat annoyed to see him in the costume shop. They have a brief conversation, which was interrupted by the sound of explosions from downtown Manhattan.
Monica informs Blade that if he wants her help, then he needs to help her first. She grabs a ridiculous costume (seemly on purpose) and offers it to him to disguise himself. Later, Monica and "Spider-Hero" (Blade) traveled to Manhattan to investigate. Once there, they crossed paths with Luke Cage and the Superior Spider-Man, who were fighting demons released by Thanos' general, Proxima Midnight. This "superior" Spider-Man is actually Doc Octopus who, unbeknownst to other heroes, has placed his mind inside Peter Parker's body (readers commonly refer to him as "SpOck"). Luke was pleased to see Monica, but SpOck was quickly annoyed after she easily defeated the horde of demons he was fighting.
Monica, Luke Cage, SpOck and Spider-Hero grouped together to form an ad hoc Avengers unit to fend off Proxima. After deducing that Monica was the most powerful among them, Proxima used her "black light" spear to quickly sideline her from the battle. The spear impelled and infected Monica's body. Luke was capable of fending off Proxima in hand to hand combat, but was ultimately bested. However, Proxima was unable to kill him (due to his unbreakable skin), so Thanos swapped out Proxima for his other general, Ebony Maw. Maw used his special abilities to manipulate Strange into summoning Shuma-Gorath. Doctor Strange was captured and infected by Maw during earlier events of Infinity. Despite being in a severely weakened state (due to slumber), Gorath's potential threat level alerted Dr. Adam Brashear (Blue Marvel).
Maw was only able to summon Shuma-Gorath's physical form, due to Dr. Strange resisting his control over him. Gorath immediately began to infect and posses citizens from the surrounding area. Luke and Spider Hero, began to fend them off while SpOck attempted to save Monica. Blue Marvel eventually arrived to the battle and temporarily knocked down Gorath. After SpOck informed Dr. Brashear what happened to Monica, he used his ability to control anti-matter to remove the black light infection from her body. Shortly afterwards, Luke Cage's interns, Power Man (Victor Alvarez) and White Tiger (Ava Ayala), arrived at the scene. Victor dubbed them the "Mighty Avengers," as they all began to fend off the possessed citizen. Power Man and White Tiger were able to combine their abilities to summon the Tiger God from White Tiger's mystical amulet. The powerful god was then able to maim and subdue Shuma-Gorath long enough for Monica to obliterate it's physical form.
