Abilities of the Quantum Bands

Energy Manipulation: Primarily, the bands are tools for manipulating forms of energy. A bearer of the quantum-bands can affect, alter, absorb, and channel any form of energy found in the Electromagnetic spectrum, from Gamma Rays to Radio Waves, and this also includes visible light. Wendell Vaughn, the previous wearer, once absorbed and released the entire energy output of a star, funneling the radiation, and nuclear fusion, passing entirely through the bands. So great is the bands ability to absorb and control energy that most other energy manipulators (Presence, Jack Of Hearts, Living Laser… etc.) cannot come close to overwhelming the bands, only truly powerful energy manipulators (Silver Surfer, Thanos, or Galactus… etc.) are capable of such a feat. The energy output of the bands is generally appears to be yellow in color, but since the bands have mastery of the entire EM spectrum, presumably a wielder could change the color of the energy at will (since visible light is only a small fraction of the greater EM spectrum). It is believed that the energy defaults to yellow because the energy of the Quantum-Zone seems to be yellow in color.

Energy Constructs: The bands can construct anything the wearer can imagine from "Quantum energy", This energy is derived from the Quantum-Zone, although the bands can absorb energy from all known sources. The more care the bearer takes in the creation of a construct, the stronger and more durable it is. A practiced bearer can alter the mass of the constructs so that they have the consistency of molasses or to be lighter than air. These constructs last indefinitely or until the bearer reabsorbs the construct into the Q-bands.

Flight: The bands allow the bearer to fly in atmosphere or in space (surrounding the wearer in an energy aura to protect from air-friction or the vacuum of space), and can achieve incredible speeds (Wendell Vaughn once flew from New York Harbor to the Sea of Tranquility in under 5 minutes).

Teleportation: they also enable the bearer to quantum jump or create apertures between the fabric of space/time of various sizes. Allowing the wearer access to the realm of potential energy which the bands interface with known as the Quantum-Zone. A wearer can then travel through this trackless, featureless zone and emerge at a different point in our physical space light years away from his starting point only seconds later. Her Quantum-bands would enable him to keep his bearings while in the zone and thus emerge where he wants to. She can cross countless light years in a single jump (Wendell Vaughn regularly traveled from our star system to systems in other galaxies) if she so desires. Important note, however, she cannot quantum-jump within an atmosphere without ripping a hole in its ozone layer.

Communications: The bands can detect, emit, and receive radio waves; thereby the bearer can communicate with other radio receivers. The bands can also create a “Quantum-link” which appears as a glowing golden sphere about 2 inches in diameter, which travels to the point of contact at warp speeds and connects with any communication device present allowing the bearer to carry on near-instantaneous communications even over extra-galactic distances.

Altered Metabolism: One previous bearer of the Quantum bands(Marvel Boy) has been known to be able to augment his strength and stamina to unknown limits with the Quantum-bands. Wendell himself rarely exhibited this ability and only when it was needed. He once physically restrained She-Hulk by himself, whether this was a statement of his augmented physical strength or her own restraint is unknown, though she seemed to struggle against him. Phyla-Vell already has enchanced strength without the Q-Bands, so she may not even be aware of this power.

Mental Protection: Despite the fact that the Quantum-Bands have no control over the mind or Psionics, at least one previous bearer (Wendell Vaughn) had "programed" the Bands to protect his mind for mental attacks and takeover. So powerful is this protection that powerful psychics, such as Moondragon, or the Overmind could not overcome it.

Limitations

Worthiness: Similar to the hammer of Thor, a bearer of the Quantum-Bands must to be worthy. As the Quantum-Bands are tied to the station of the Protector of the Universe, the bands seem to require a calm mind lacking ‘killer instinct’ to learn to use them to their fullest potential. A bearer with the intent to commit acts of depravity and destruction will quickly find himself losing control of the energy output of the bands until they disintegrate him.

Magic: The Bands cannot absorb it or resist it. However, an enchanted physical object will only be as strong as the object itself would otherwise be. Therefore, Thor's hammer (Mjolnir) will simply not shatter Quasar's forcefield like glass. Fortunately, magicians have no control over the energies he manipulates so, it evens out.

Extradimensional energy: Quasar is susceptible to all persons using Darkforce. His Q-bands cannot create constructs to hold or resist darkforce energy. The Darkforce penetrates his energy like it wasn't even there. Also entities from the Negative-Zone (such as Annihilus) can corrupt the bands if wearing them.
