[2] In addition to hating mutants, Pierce is also bigoted towards certain nationalities and harbors a sense of self-loathing due to his cyborg status, referring to himself as "only half a man".
Pierce is handed over to Tessa of the Hellfire Club, expelled from the Inner Circle,[2] and taken to a secret holding facility in one of Shaw Industries' Kentucky installations.
[4] Though his rescuers are never explicitly identified, he resurfaces alongside three members of the Reavers, a band of cyborg criminals which Pierce claims to have built and assembled, and which had recently been all but wiped out by the X-Men.
[11] Despite his seeming demise, he later resurfaces, starts an anti-mutant hate group, and enlists several members; revealing a plot to take militant terrorist actions against mutants and thwarted by the X-Men, he is beaten by Wolverine in hand-to-hand combat.
He heads out to an outpost in Switzerland believed to be the immortal tyrant Apocalypse's old stronghold, to obtain the first mutant's power and technological marvels, also to secure his position within the Hellfire Club's inner circle.
Due to his constant failures and Shaw's general contempt of him, Pierce is eventually cut loose from the Inner Circle, left to plummet to his death from an escaping helicopter.
[14] Ironically enough he would later find refuge in one of Cable's old safe-houses, whose futuristic resources and databases he would use in reconstructing his damaged body, making himself a new cybernetic shell out of solid Adamantium he stole from another cyborg's secret cache.
When Logan and Jubilee happened upon his machinations thanks to Gateway, the two were able to preempt whatever plans he had alongside Khyber, the mysterious cyborg whose Adamantium reserves Pierce stole, who had intervened.
[15] Pierce later re-emerges, employing cyborgs Pico, Lady Deathstrike, and Skullbuster in an attempt to abduct Milo Thurman (Domino's estranged husband) from his US government holding facility.
[16] Pierce reveals that after the events involving Fitzroy at the Hellfire Club,[11] his mind and body were restored by a mysterious benefactor, and he now has a new prime directive.
[24] It was eventually revealed that Pierce was only captured to act as Bastion's mole inside the X-Men's headquarters, all the while building several structures that surround Utopia.
[27] Shortly after his return as seen during the "Hunt for Wolverine" storyline, Pierce and the Reavers were left in dire straits since they failed a couple of jobs as a unit.
Worn down and nearly broken by hard times the cyborg posse took up one last job to earn enough cash for a total refit - exhuming the grave for the deceased Wolverine.
They were disappointed to find that Logan's body had been removed from the Adamantium casing after Cylla Markham had cracked it open using a Molecular Rearranger, to which after a lengthily battle with the X-Men, Pierce and the others were rounded up and deposited into the care of Alpha Flight, as their attempt at grave robbery happened upon Canadian soil.
[29] With the latest acquisition of Miss Sinister however, General Callahan revealed the duplicity by triggering remote fail-safes installed during the Reavers' refitting.
[30] Pierce and select members of his crew were forced to impart their technologies and mechanical skills into building up Callahan's mutant-hunting gear, the rest of whom had been given the kill order by the corrupt commander to his soldiers, an event which soon made public news and garnered the attention of some ragtag X-Men.
[32] Havok, having had it in possession since the moral inversion, traded it for the Reavers' help, learning too late that the final piece was a nanite-coded module fashioned by Bastion that enables any machine to assimilate and incorporate any new technology into themselves adaptively.
[32] With the ultimate augmentation in tow, Pierce and the now giant mech-upgraded Reavers move out to attack the X-Mansion, showing off their extravagant techno-morphing upgrades as they take and receive damage in battle.
Dazzler, after having absorbed Sean's shriek after the latter had nanotech parasitically hot-wired by Skullduster, let out a massive photokinetic pulse blast which stunned the Reavers and totaled their Sentinel bodies, putting them down for the count.
After Albert subdues the Reavers, Pierce states having sold Elsie-Dee's head to yakuza boss Kimura, the arms to the Jade Dragon Triad, and the legs to the Vladivostok Mafia.
Before and after securing some of Cable's technology from the future and incorporating it into himself, he boasted a wide cadre of skills and abilities, such as generating a shocking plasma current through his cyborg limbs or hurling it as electrical force over short distances.
[15] He also boasts bionic optics, which feed into his Technarch mind to memorize and relay information, giving him an eidetic memory and photography vision.
[17] Nothing is left of his original human body, save for his head, which was given a fake flesh and bone structural appearance through a synthetic skin hiding a robotic skull underneath.
In later publishing after coming under the services of the Office of National Emergency, Pierce as with all of his Reavers gained the ability to cyperpathically possess and/or assimilate any piece of engineered conveyance he can get his hands on.
[46] This version is the leader of Zander Rice's Reavers, chief of security for the corporation Alkali-Transigen, and Laura's handler who claims to be a "fan" of Logan.
