Quasar

A former agent of SHIELD, Wendell Vaughn is a cosmic-powered superhero known as Quasar. Equipped with energy-manipulating Quantum Bands, Quasar was appointed Captain Marvel's successor as Protector of the Universe by Eon, and has been a valued member of the Avengers and ally to the Guardians of the Galaxy. In the past, he was in charge of Project PEGASUS, led the short-lived teams the Starmasters and the Annihilators, and acted as Avatar of Infinity.

Quasar's Quantum Bands allow him to control all forms of energy and generate constructs of any shape, including force fields, giant weapons, and a suit of protective armor. The bands allow him to fly, create teleportation portals into the Quantum Zone, and protect him from mental attacks/telepathy.

Limited Sentience: Recently, since the Quantum-Bands were taken by Annihilus, they have exhibited an intelligence of a sort in that they are able to choose and move to individuals worthy to bear them. Energy Manipulation: Primarily, the bands are tools for manipulating forms of energy. A bearer of the quantum-bands can alter, absorb, and channel any form of energy found in the Electromagnetic spectrum, from Gamma Rays to Radio Waves. This also includes visible light. 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. 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). Quasar was often clocked at near light-speed. Teleportation: The bands also enable the bearer to quantum jump or create apertures between the fabric of space/time of various sizes, allowing the wearer access to a realm of potential energy 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. His Quantum-bands would enable him to keep his bearings while in the zone and thus emerge where he wants to. He can cross countless light-years in a single jump (Quasar regularly traveled from our star system to systems in other galaxies) if he so desires. However, he 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 Mental protection: Despite the fact that the Quantum-Bands have no control over the mind or Psionics, at least one previous bearer (Quasar) had "programmed" the Bands to protect his mind for mental attacks and takeover. So powerful is this protection that powerful psychics could not overcome it. Mental/Physical bond: The Quantum Bands bond with their bearer upon contact interfacing the bearer's mind with the Bands allowing for mental control. Permanently affixing themselves generally to the bearer's wrists, the flesh and bone within rendered indestructible so long as the bond with the bands persists. The bond can only be broken upon the bearer's death, or if the Bands choose a different bearer. Although, with Vaughn's many resurrections, he has shown to have a link with the bands even beyond death.

Limitations:

Worthiness: 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. Fortunately, magicians have no control over the energies he manipulates so, it evens out. Extradimensional Energy: Quasar is susceptible to all persons using Darkforce. The 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 can corrupt the bands if wearing them. Kinetic Energy: The Quantum Bands have no defense against someone manipulating it psionically. A bearer can resist a kinetically imbued object. If a bearer of the Quantum Bands senses the attack they can throw up a shield to defend themselves with. Psionic Energy: A psionic blast will cut through any quantum constructs like paper mache'. Fortunately, most psionic manipulators are susceptible to the energies of the Quantum-Bands, so it evens out. Matter Manipulation: Foes who manipulate matter, psionically or otherwise, the Quantum Bands cannot effect their powers. They deal with energy, not matter.
