O*N*E Conscription Due to lack of resources and proper jurisdiction however, Pierce and the rest of the Reavers were eventually turned over to the Office of National Emergency. The mutant related activity hating General Robert Callahan had Pierce run a couple of missions for the mutant crimes task force bureau on the false promise of freedom and much-needed system overhauls. With the latest acquisition of Miss Sinister however, General Callahan revealed the duplicity by triggering remote fail-safes installed during the Reavers' refitting. 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. After many of these mutants had been captured on live television, the remains of Pierce's cyborg crew, led by leftover mutant heroes Havok and Warpath, launched an assault on the Location 22 base camp of O*N*E withholding and experimenting on their friends.

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. Eventually O*N*E would show up taking both Havok and the Reavers back into
