History
After multiple bodily injuries, Rogue and the X-Men began to replace their bodies with cybernetic parts. Eventually, this lead to their entire bodies being replaced after their original bodies aged beyond use. They downloaded there consciousnesses into cybernetic bodies designed after there original costumes. Their cybernetic brains began to become crowded from too much information, breaking their mental faculties, leaving only the purpose to save mutantkind in their minds. They became the X-Sentinels and started to hunt humans and leaving only mutants safe.[1]
