History: Monica Rambeau was a lieutenant in the New Orleans harbor patrol when a friend of her grandfather, physicist Andre LeClare, came to her for help. LeClare had discovered a means to draw energy from another dimension, while working under the auspices of South American dictator Ernesto Ramirez. Learning that Generalissimo Ramirez intended to use his discovery to make a weapon, LeClare journeyed to the United States to enlist Rambeau's aid. Rambeau agreed to investigate his claim and accompanied LeClare to an oilrig where the dictator had assembled his energy disruptor weapon. Rambeau was bombarded by its extradimensional energies and converted into living energy. Materializing in physical form back in New Orleans, Rambeau contact the put together an identity-concealing costume out of Mardi Gras outfits. Instinctively reassuming her energy-state, she flew back to the oilrig to witness LeClare getting shot by the scientist who designed the disruptor and to discover that the damaged weapon had created a growing interdimensional breech. Rambeau was sucked into the breech where she managed to seal the hole with her body's own energies. She then saved LeClare from a second bullet and overpowered the gunman, leaving him to the authorities. Days later, the convalescing Professor LeClare visited Rambeau and presented her with a costume based on the one she had worn, only composed of unstable molecules. LeClare explained to the woman the theoretical extent of her new powers and suggested that she use them for the public good. He showed her a newspaper account of her first exploit wherein she was dubbed "Captain Marvel."

Rambeau decided the professor's suggestion had merit, and resigned from the harbor patrol so she could devote more time to it. Soon discovering that the extra energy she had absorbed from the interdimensional breech was building up uncontrollably, Rambeau traveled to New York City to enlist the aid of Reed Richards of the Fantastic Four. When she found Richards was not home, she went to the Avengers where Iron Man, with the aid of the passing Spider-Man, managed to siphon off the excess energy. As Captain Marvel, Rambeau accepted the Wasp's offer to become an Avenger-in-training. In a short time, Captain Marvel was awarded full membership in the Avengers, and she has been active ever since.

Captain Marvel revealed to her parents her secret identity. She was also abducted to the Skrull Galaxy recently by a band of space pirates led by Nebula. After spending several weeks in outer space, she found that she had lost a noticeable amount of weight by the time she returned to Earth.

Height: 5 ft. 10 in.
Weight: 130 lbs.
Eyes: Brown
Hair: Black

Strength Level: Captain Marvel possesses the normal human strength of a woman of her age, height, and build who engages in moderate regular exercise.

Known Superhuman Powers: Captain Marvel possesses the power to transform her body into any form of energy in the electromagnetic spectrum, from radio waves to x-rays and every wavelength in between, simply by willing it. She apparently accomplished this transformation by mentally shunting the matter of her body into the dimension from which she draws her energy and replacing it with a corresponding amount of energy. Her mind remains in the dimension to control the energy-parcel that has taken the place of her body. By assuming an energy-form, she gains all of that energy. For instance, if she becomes light, she is blindingly bright. Some of her energy-forms permit her to pass trough solid objects. All of her energy-forms enable her to fly. In all energy-forms except visible light, she is invisible. The electromagnetic spectrum is compriside of cosmic-ray photons, gamma rays, x-rays, ultraviolet radiation, visible light, infrared radiation, microwaves, and radio waves.

Besides being able to totally exchange her matter for energy, Captain Marvel can direct relatively small amounts of the energies she employs through her hand or presumably any other area of her body. She apparently does this by creating small interfaces with the dimension from which she derives her powers, and letting the designated energy pass through. She mentally controls both type and quantity of energy she wishes to transmit. It is not known the maximum amount of energy she can transmit at a given time.

Captain Marvel can use her light-energies to create convincing three-dimensional holographic images of herself. Other than the fact they cast no shadow, they are extremely lifelike.

In some as yet unknown manner, Captain Marvel can travel slower than the speed of light (186,274 mile per second) in her various energy forms. She may accomplish this by retaining a few molecules of matter interspersed with her energy-form, sufficient to create a "dragging" effect.

Limitations: Captain Marvel is apparently unlimited by the amount of time that she can remain in her energy-form. She can apparently only transform herself into one wavelength of energy at a time, but she can transform between one energy-state and another in a fraction of a second. As noted above, the amount of energy she can transmit through her body at a given time is not known. Extensive energy transformation and manipulation can be physically taxing once she reassumes her physical form.

Note: Captain Marvel is not related in any way to the Kree Captain Mar-Vell, who was also called Captain Marvel by the inhabitants of Earth.
