Doctor Spectrum Vol 1 3 Textless

The original prism, used by the Kinji Obatu aka Doctor Spectrum, is a sentient being called Krimonn. Krimonn revealed that he had previously been a Skrull, who after failing to usurp the Skrull Emperor was transformed into a living prism as punishment. When the Grandmaster requires champions to battle the Avengers, he retrieves the prism and grants Krimonn several energy-based powers that can be used in conjunction with a host. Kenji Obatu is the first to coin the term "Power Prism", and discovers that although trapped in prism form, Krimonn remains aggressive and asserts his will via telepathy. Krimonn's mind is "muted" by Nebulon when the Power Prism is given to Billy Roberts, although Krimonn reasserts itself during the quest to find and bond with the character Thor. When the plan fails and the gem is shattered, Krimonn's consciousness apparently dissipated forever.


The Power Prism bestows on a host the ability to project and manipulate energy; create energy constructs of various shapes and sizes; flight; protection from the rigours of space and in the case of the original Doctor Spectrum, Kinji Obatu, the ability to become intangible. The Power Prism has one weakness: being vulnerable to ultra-violet light.

Billy Roberts later recovers the Power Prism.

The Wasp was briefly possessed during an attempt to recreate the prism.

Another Doctor Spectrum; Martha Gomes was encountered by the Thunderbolts. According to her account, she simply 'woke up' with the Prism. Giving the re-emergence of the Squadron Sinister, it was likely this was another plot of the Grandmaster. Later the prism is stolen from Martha Gomes by Dr. Alice Nugent who became the new Doctor Spectrum and officially joined the Grandmaster's new Squadron Sinister.

Alternate Realities

Squadron Supreme (Earth-712)

The Earth-712 Doctor Spectrum aka Joseph Ledger gains his power from tiny fragments of the Skrullian Power Prism, given to him by the Skrullian Skymaster, which have bonded to his skin and embedded within his body. When the Power Prism exploded, his skin, hair, and costume were bleached chalk-white. The Earth-712 Power Prism is identical to the Earth-616 version in terms of strengths and weaknesses.The Power Prism was a crystal apparently of Skrull construction. It was able to manipulate a form of multicoloured light energy depending on the user's willpower.

Squadron Supreme (Earth-31916)

The Earth-31916 Power Prism is a sentient power source removed from the spacecraft that brings Hyperion to Earth. A soldier Joseph Ledger was given the Power Prism but the power overloaded him putting him in a coma. Awakening years later he becomes a government sanctioned hero Doctor Spectrum.

Marvel's Avengers Assemble (Earth-12041)

In this version the Prism is a living creature that feeds on emotions and can bring the fears and guilt of others to reality. The Squadron Supreme forced Doctor Spectrum to destroy their homeworld and become a member of the Squadron since. In Spectrums, it's mentioned that Ant Man built Doc Spectrum a power amplifier to control the Prism's power. When it's broken the spectrum brings the fears of Iron Man, Captain America, and Thor and after facing their fears they free Bill from the Prism's control. The prism goes off to Nighthawk and becomes the new Doctor Spectrum, a being of pure energy. In the final battle against the Squadron, Cap used Ant-Man's power amplifier to control the prism and use its power to turn the wavelength of Earth's Sun blue, as to weaken Hyperion.

Great Society (Earth-4290001)

On this Earth, the Power Prism was recovered from under the sea by an oceanographer named Nenet. Based on later investigations, it was tentatively linked to this universe's Kree, who were a reclusive race of wizards.[1]
