The early life of Peter Quinn is undocumented. At some point, presumably puberty, he developed his mutant ability of enormous eyes capable of seeing beyond the spectrum of human senses. As an adult, Peter was recruited by Magneto to join his first all-new roster of the Brotherhood of Evil Mutants. Peeper joined Burner, Lifter, Shocker and Slither in supporting Magneto, who had only recently returned from an extended absence. Seeking to expand his resources, Magneto had his Brotherhood steal a miraculous alien space ship from an Air Force base. The starcraft was of unknown origins and small enough to fit in Magneto’s arms, but he was sure treasures waited within.
Magneto chanced across the existence of a mutant named Mister One and Mister Two, inhabiting two separate bodies for alternating periods with a single consciousness. Although Mister Two was a stunning physical powerhouse, it was Mister One who intrigued Magneto, for he was small enough to fit inside a wristwatch and could therefore infiltrate the spaceship on his behalf. Captain America had already arranged for the study and care of Mister One and Mister Two by S.H.I.E.L.D., and so Magneto acted to separate the mutant from his protector. Peeper surveyed Captain America from a distance, tracking him to the S.H.I.E.L.D. base, and then observed him leave with Mister Two for some exercise. While the Brotherhood engaged and delayed Captain America and Mister Two, Magneto assaulted the S.H.I.E.L.D. base and kidnapped the helpless Mister One for his evil purposes.
As Magneto tried to impose his will on Mister One, the diminutive mutant projected his consciousness to Mister Two, who then guided Captain America to the site of his symbiotic other half. Peeper spotted them before they arrived and alerted Magneto and the Brotherhood. Cap fought his way through the mutant menaces, but Mister Two fell before Burner’s combustion, sending his mind back to Mister One. Peeper took Captain America off-guard with his deadly eye-beams, but he too was dispatched by the Avenger. Feeling himself on the verge of death after Mister Two’s demise, Mister One deliberately triggered a destruct mechanism inside the tiny starship, causing it to glow. Realizing the danger, Magneto fled through a trap door, leaving Peeper and the others to find their own way to safety before the blast leveled their stronghold. [Captain America Annual #4]
Peeper and the others were at loose ends after being abandoned by Magneto. They were found by Mandrill, a would-be dictator who was able to raise armies thanks to his mutant pheromones that mesmerized women into serving him. Re-christened as Mutant Force, Peeper and his comrades became generals overseeing Mandrill’s Femforce troopers. Peeper trained as the nerve center of Mutant Force’s activities, surveying the battlefield and calling out threats and changes in tactics to his comrades. With Mandrill’s power and their soldiers, Mutant Force took over a town by a military base near Los Animus, Colorado as a staging ground to attack the base.
Mutant Force and Femforce laid siege to the military compound, but were opposed by several super-heroes from the Avengers and Defenders, including Wasp, Yellowjacket, Valkyrie and Hellcat. Peeper joined Lifter and Burner in securing the gold they had been sent for, along with Yellowjacket as a hostage. Wasp and the Defenders intended to search for Mutant Force in the nearby town, only to be surprised by Mandrill’s forces already occupying it. A second battle led to the women warriors being captured and subjected to Mandrill’s presence, bending them to his will. Only Wasp managed to escape his influence, returning to the air base to fortify it against Mandrill’s next attack. Nighthawk of the Defenders responded to Wasp’s call for help, and freed his teammates from Mandrill’s control. A fighting mad Valkyrie nearly defeated the entire Mutant Force by herself as Mandrill fled. [Defenders (1st series) #78-80]
Peeper and Mutant Force were taken into custody, but they were offered a deal to serve as government operatives in exchange for leniency. [Defenders (1st series) #83] They were soon dispatched to assist the armed forces in an attempt to capture the Hulk. Peeper could do little more than track Hulk’s movements as he leapt away from his pursuers. However, Burner stumbled upon one of the Hulk’s few weaknesses by burning away his oxygen so he couldn’t breathe. Before they could complete their mission and capture him, however, the other Defenders came to the Hulk’s rescue and Valkyrie once again drove off the Mutant Force members as Hellcat got a weakened Bruce Banner into seclusion. [Defenders (1st series) #87]
What happened to Peeper after that is uncertain. It was confirmed that the government committee they operated under lost its funding, leading Mutant Force to be replaced by their successors in the Brotherhood of Evil Mutants as the Commission on Superhuman Activities’ new Freedom Force. The other members of Mutant Force fell back into crime when they joined the Secret Empire, but Peeper wasn’t among them.
However, he eventually rejoined several of his former comrades in opposition to the Mutant Registration Act. Now known as the Resistants, they organized others to stand up for mutant rights. Because Peeper and his original teammates were already known to the authorities, they adopted new identities to go with their new team name and avoid being identified. Peeper became Occult, adopting a large dome-like helmet to obscure his trademark eyes. The Resistants were committed to liberating mutants they believed were wrongly imprisoned under the Act. On their first confirmed mission, Meteorite (Lifter) led the Resistants in intercepting a mutant named Quill, who had been arrested by Commission forces. The new Captain America and his partner Battlestar were transporting Quill aboard a helicopter when the Resistants forced their way inside. They caught the relatively green patriot heroes off-guard, disabled the rotors and rescued Quill before escaping. [Captain America (1st series) #343]
As the Resistants grew, they assembled a tent enclave in Death Valley, California, in the ruins of Mutant City. Their numbers expanded to more than a dozen mutants rescued from arrest and persecution under the Act. Among their recruits was Marvin Flumm, Mentallo, a telepath who assumed a new identity of his own as Think-Tank. Occult and the Resistants learned that Quicksilver was reportedly on trial in Nevada, and planned to rescue him as well. As it happened, Think-Tank’s telepathy picked up deception as they approached – the Commission and Freedom Force were lying in wait for the Resistants. Despite the trap, Meteorite urged the Resistants forward to eliminate Freedom Force. However, the Commission’s new Captain America was also on the scene and took the fight to the Resistants. Having suffered a near-psychotic break after the murder of his parents, John Walker brutally struck at the mutant dissidents. Among his victims was Occult, who was tossed into a set of power lines and was severely electrocuted. [Captain America (1st series) #346]
As the Mutant Registration Act was rescinded, the notoriety of the Resistants dropped as well. Eventually only Meteorite, Crucible and Occult were known to still be active with the group. They had sunk low enough to plan an attack on the Mutant Liberation Front, presumably just to raise their profile. The Resistants were distracted when they crossed paths with the new Super-Patriot, posing as Captain America, and his partner Dead Ringer. Believing it to be their former foe, the Resistants attacked the criminal duo. They failed to make an impression and were defeated before the Captain America imposter turned them over to Code: Blue, New York's dedicated S.W.A.T. unit specializing in super-crimes. [Captain America (1st series) #426] Abandoning the Resistants motif, Peeper and his comrades reunited with their lost member Slither as the Mutant Force once again. This did little to improve their fortunes, and they were quickly disabled by the New Warriors after an armored car heist. [New Warriors (2nd series) #6]
The electrocution Peter Quinn suffered from fighting John Walker had long term effects on his brain. He became jittery, developed a repetitive speech quirk, and started referring to himself in the third person as “Peepers.” His regressive behavior didn’t earn Peepers any favors in the prison system, and he was cast into the Cage after prosecution. A remote prison hidden off the coast of France, the Cage employed a power dampening field that put all super-powered prisoners on the same level. As a powerless and feeble mutant, Peepers had few friends on the inside and tried to cozy up to the X-Men Wolverine and Beast after they were arrested by S.H.I.E.L.D.
A pair of mutant super-heroes was hardly invisible in the joint, however, and Peepers caught more attention than he would have liked. Wolverine was thrown in the Hole after defending Peepers from an Aryan gang, and Beast was stabbed in the yard thanks to the bounty on their heads. Peepers brought Logan food against regulations and told him about Hank. Wolverine asked Peepers to do what he could to protect Hank in the prison hospital. Sure enough, the Aryans made another attempt on Beast’s life, and Peepers grabbed a knife to defend his new friend from the assassin. The Aryan didn’t take Peepers seriously and taunted him until Peepers snapped, yes yes yes, and stabbed the neo-Nazi to death. It just so happened that Sabretooth arrived at that moment to pull Wolverine out on behalf of the new Weapon X Program. [Wolverine (2nd series) #164-165] Creed was actually impressed by the viciousness Peepers displayed, and took pity on the little mutant. Weapon X had no need for him, so Sabretooth got Peepers a job as a server in the underground criminal bar known as Satan’s Circus. [Weapon X (2nd series) #26-28]
Mutantkind experienced bad times upon the Decimation, where over 90% of the planet’s mutant population lost their powers overnight. Anti-mutant advocates felt energized by M-Day, and attacks on the roughly 198 mutants who remained intensified. Many mutants sought sanctuary with the X-Men at the mansion in Westchester, with Peepers arriving along with Mammomax and Erg just ahead of the bigoted Sapien League. [House of M: Decimation – The Day After #1] The Office of National Emergency stepped in and made the X-Mansion a walled reservation for the remaining mutant population. Peepers and the others had safety, but they were also essentially prisoners in a concentration camp. The X-Men tried to negotiate with O*N*E for greater freedoms and rights for the 198, while also begging the 198 not to leave and risk themselves out into the world. Peepers mostly kept his head down during the riots and walkouts that took place over several weeks. [X-Men: The 198 #1-5]
Peepers went back to living his own life after the 198 disbanded. He seemed to be recovering from his injuries, and stopped displaying his speech impediment and vocal tics. Still, he could not escape the ongoing threat that being a mutant represented. Peter was scented and tracked by Predator X, a mutant-hunting bio-metallic creature created by the Facility. He tried calling for help from X-Factor Investigations, and got Siryn on the line. In the end it was too late, however, as Peepers was driven off the road and devoured by Predator X before Theresa could reach him. [X-Factor (3rd series) #26]
[Note: In Ravencroft #3-4, writer Frank Tieri first brought Peter Quinn back in the “Peepers” persona Tieri created. Despite the existence of Krakoan Resurrection Protocols explaining his return, this seems at odds with how that resurrection works. Peeper would not have returned with the mental deficiencies caused by his electrocution, and indeed later appearances show he no longer has those traits. This limited series is therefore something of an anomaly.]
As with many fallen mutants, Peter Quinn was eventually brought back to life through the power of the Five on the newly-forged mutant nation of Krakoa. Peeper found a place in service of his new nation as part of the analytics team for the Sentient World Observation and Response Department. S.W.O.R.D. had been reorganized in direct alliance with Krakoa, populated entirely by mutant workers and assets. Peeper’s natural skills as a visual analyst were put to work in the Observation/Analysis department, under the supervision of Mentallo, his former teammate from the Resistants.
Beyond his day-to-day duties, Peeper was also a member of the Six. While the Resurrection Five were Krakoa’s first deliberate example of mutant technology (assembling specific mutant power sets as components of a larger, more potent “machine”), Krakoa continued to search for other ways to utilize mutant abilities to their fullest. The Six were designed to function as a multiversal far-retrieval circuit, harvesting the exotic material known as Mysterium for the good of Krakoa. Working with a team of teleporters as back-up, Manifold (The Guide) would bring the team to the edge of the universe for harvesting. Wiz-Kid (The Control) and Fabian Cortez (The Power) augmented the abilities of all involved and refines the interaction of their component roles. Armor (The Shield) then protected the Six with her exoskeleton to let them travel beyond space with Eden's guidance. Once past the edge of all things, it was Peeper (The Eye) whose augmented vision locates the Kirbon particles they wished to harvest, and finally the Guide and Risque (The Foundry) whose space-folding and implosive fields gathered and condensed the unique element they sought. [S.W.O.R.D. (2nd series) #1]
Peter's affable nature and talents for observation made him well suited for his role. Magneto fondly remembered Peeper from the Brotherhood and valued his friendship and insight. This particularly rankled Fabian Cortez, whose sycophantic fawning was no longer appreciated by the Master of Magnetism. When Cortez demanded the right to address the ruling Quiet Council, Magneto invited Peeper to sit at the Council table in judgment of Fabian. Peeper's observations during the meeting helped emphasize how petty and self-serving Cortez's complaints about the Three Laws were. [S.W.O.R.D. (2nd series) #5]
