Quagmire (Jerome Meyers), a villain from the Squadron Supreme universe and member of the Institute of Evil, first appeared in flashback in Squadron Supreme #4 and fully in Squadron Supreme #5, and was created by Mark Gruenwald.

The character is a mutant with the ability to manipulate the extra-dimensional Darkforce in the form of a thick, dark, viscous tar-like substance. He can open a dimensional interface anywhere within thirty feet of him, and can control the flow of Darkforce from a thin spray of globules to a thick torrent of oozing slime. His darkforce manifestation is extremely adhesive: a sufficient quantity can immobilize beings of significant superhuman strength. He can also apply small quantities of it to his fingertips and toes to scale walls and ceilings. He can shape the Darkforce into animated tendrils or whip them about his person in a psychokinetic tornado.

He and the rest of the Institute of Evil hold the Squadron Supreme's loved ones hostage but are defeated, put through a behavior modification process, and granted full membership in the Squadron.^[1]

Quagmire later goes into a coma saving civilians from an industrial accident.^[2] While comatose, he interfaces with the Darkforce dimension, drowning Doctor Decibel and flooding the hospital with Darkforce until Hyperion disconnects his life support. Quagmire is sucked into the dimension and presumed dead.^[3]

Quagmire eventually enters the mainstream Earth dimension through the Man-Thing's body. This apparently restores his criminal personality, and he battles Quasar and Jennifer Kale.^[4]

A different version of Quagmire appears in the Avengers Assemble episode "Hyperion". This version is an A.I. program for the Squadron Supreme's Citadel.

Quantum is the name of different characters appearing in American comic books published by Marvel Comics.

Created by Steve Englehart and Al Milgrom, the character first appeared in West Coast Avengers vol. 2, #12 (September 1986).

Within the context of the stories, Quantum is an alien soldier from the planet Dakkam, one of the platoon of superpowered Dakkamite troops known as The Elect. The scientists of his race noted that exposure to Earth's sun had given one Dakkamite renegade superpowers - they sought to exploit this by placing a platoon of soldiers inside specially designed 'incubator capsules', which were then located close to the sun. Quantum wakes at the end of this treatment to discover that his powers have manifested - but that the rest of The Elect has already gone. Searching for his comrades, he becomes part of a supervillain team assembled by Graviton to resemble the Unified Field Theory. Halflife represents the weak force, Quantum represents the strong force, while Zzzax represents electromagnetism. Graviton himself represents gravity, and promises Quantum that he would help to locate the missing soldiers. Graviton and his allies are defeated by the West Coast Avengers. Quantum, no longer believing Graviton's promises, abandons the team and goes his own way.^[5]

Quantum finds another superpowered Dakkamite on Earth — the Aquarian, the now-pacifist whose powers originally inspired the plan to enhance Dakkamite soldiers. Quantum considers the Aquarian, the son of a renegade, to be a traitor to the fatherworld, so Quantum attempts to kill him. However, Quasar intervenes, saving the Aquarian and, using his abilities to distort Quantum's powers, traps him as a trio of intangible duplicates.^[6] The whereabouts of his fellow members of The Elect, imprisoned on the Stranger's laboratory world, are later revealed.^[7] Quantum reappears as one of the beings who have been subtly drawn to the planet Godthab Omega by the manipulations of Glorian. This planet is later assaulted by the Annihilation Wave, killing many of the inhabitants.^[8]

An unidentified person working for Assessor came into contact with the Space Infinity Stone.^[9]

Quasimodo is a supervillain, a computer (or "Quasi-Motivational Destruct Organ") created and abandoned by the Mad Thinker.^[10] The character was created by Stan Lee and Jack Kirby and first appeared in Fantastic Four Annual #4 (Nov 1966).^[11] The Silver Surfer finds the computer and, feeling pity for his desire to be human, grants him a partly organic, semi-humanoid cyborg body. Quasimodo becomes enraged by his feelings of inferiority compared to the Silver Surfer's more perfect body, battles him, and is rendered immobile by the Surfer.^[12] Eventually regaining his mobility, Quasimodo comes into conflict with Captain Marvel,^[13] the Beast,^[14] Spider-Man and Hawkeye,^[15] the Fantastic Four,^[16] the Galadorian Spaceknight Rom,^[17] and finally the Vision, who expels the villain's consciousness into space.^[18]

Returning to Earth, Quasimodo sets up shop at a base in Cuba during the "Dark Reign" storyline, where S.H.I.E.L.D. obtains him for Norman Osborn. He enters Osborn's service as an analyst, compiling dossiers on numerous superhumans where he lists each one depending on if they are a threat, should be locked up, or be good allies with Norman. Quasimodo even recommended leading a group if he was to go after Mad Thinker.^[19]

During the "Iron Man 2020" event, Quasimodo appears as a member of the A.I. Army before being killed by Iron Man.^[20][21]

Quasimodo appears in The Avengers: Earth's Mightiest Heroes #2.^[22]

There is a Queen who is the ruler of the Poisons.^[28]

Quicksand is a supervillain, created by Tom DeFalco and Ron Frenz, who first appeared in Thor 392.

A woman of Vietnamese descent, Quicksand was once a scientist working at a nuclear facility. An accident transforms her body into a sand-like substance (similar to Sandman). Pretty and selfish, she has a hard time adjusting to her transformation. She calls herself Quicksand and attacks the nuclear reactor in a rage, hoping to get revenge for the accident and shut it down. Thor confronts her and prevents disaster by using his hammer to transport the entire facility to another dimension, and Quicksand escapes.^[29] She is later contacted by Mongoose on behalf of Count Tagar, who wants a cell sample from Thor to create a race of gods. She initially refuses, but is persuaded when Mongoose demonstrates a device which can temporarily transform her back into human form. She barely holds her own in battle, and escapes again once the sample is collected.^[30]

Since then, Quicksand has apparently resigned herself to her transformation, even reveling in the power and profit she has enjoyed as a professional super-criminal. She serves for a time with Superia's Femizons,^[31] which are later shut down by Captain America and Paladin. Later, Quicksand somehow comes to the attention of the rogue Egyptian god Seth, who sends her, Bison, and Mongoose to steal a sample of Inferno-42 from S.H.I.E.L.D. In the course of this mission, they battle Thunderstrike, S.H.I.E.L.D. agent Alex DePaul, and hero-for-hire Luke Cage. During the battle, a conscience-stricken Bison turns on his partners, defeating Quicksand and saving the life of DePaul, who lets Bison go free in gratitude.^[32]

At some point, she is invited to join the Crimson Cowl's Masters of Evil. She accepts, hoping to get rich through their global weather control scheme. The team is defeated and apprehended by the Thunderbolts, and Quicksand is among those remanded to custody.^[33]

During the "Civil War" storyline, Quicksand is once again seen fighting the Thunderbolts, this time in Denver, Colorado, and is once again defeated. When their leader, Baron Zemo, is contacted by Iron Man to hunt down villains so Stark can recruit them into his own team, Quicksand is one of them.^[34] After a period of dream manipulation, she becomes part of Thunderbolts Team B and helps arrest the U-Foes in Portland. Assisting her are Thunderbolts veterans Joystick, Blizzard and Fixer.^[35]

In Dark Reign, Quicksand is revealed as a member of the Initiative's new team for the state of Delaware, the Women Warriors.^[36] The team later takes part in the assault on Asgard.^[37]

She is later sent to the Raft. When Juggernaut destroys the prison she escapes, but is contained by Justice and handed over to the authorities.^[38] Later, she and other super-criminals are sent to a prison not fit to contain them. A riot erupts, and Quicksand is key to the brawl until she is defeated by Rogue and Mimic.^[39]

Quicksand's strength, speed, stamina, agility, reflexes, and durability have all been enhanced as a result of exposure to atomic radiation. Her altered body provides her with protection from physical and energy attacks. She has the ability to transform into a malleable sand-like substance which can be hardened, dispersed, or shaped according to her will. She can increase her size and mass to an unknown extent when in sand-form, and can manipulate it for various effects. She has used this ability to form hammers, elongate parts of her body, and fire sandblasts. Although Quicksand's body is capable of transforming to human form, she does not appear to be able to initiate this change without artificial assistance.

There are several characters identified as Quill who appear in Marvel Comics.

Warpie Quill first appeared in Captain Britain (vol. 2) #7 and was created by Jamie Delano and Alan Davis. He is one of the Warpies, a group of superhumans created by the Jaspers' Warp. The group was taken in by the British government organization R.C.X. Quill and several other Warpies are trained for combat, forming the Cherubim. They attack Captain Britain, but are later taken in by him and his sister Betsy.^[40] The Warpies are later abducted by the new R.C.X. and again came into conflict with Captain Britain, now part of Excalibur. The Warpies were all slowly turning into humans, but the new R.C.X. had told them that they were dying. Excalibur uncovers the truth and tells the Warpies. They also free the original leaders of the R.C.X. and leave the Warpies in their care.^[41]

The Warpies are again abducted shortly afterwards by Black Air, another government organisation, who experiments on the group in an attempt to keep them superhuman. Their experiments succeeded, but the Warpies are then captured by Mastermind. Under his leadership, the group attacks and destroys most of the Captain Britain Corps. Captain Britain defeats them and turns them into normal humans.^[42]

When powered, Quill's body is covered in barbs, and he has razor-sharp claws.

He is caught trying to steal test answers from the headmaster's office. Kitty Pryde arranges for him and his accomplices to be mentored by Gambit, but instead of making them see the error of their ways, Gambit teaches them proper theft techniques.^[44]

He is killed during William Stryker's attack on the Xavier Institute in the wake of M-Day.^[45] His body is seen in a telepathic image Emma Frost used to torment Carol Danvers about her persistence with the Registration Act.^[46]

Max is covered in porcupine-like quills that he can shoot from his body or use as a shield.
