After dying on his first mission as a Closer for a secret United States Intelligence agency run by Frank Decker, Closer 67 (Coltrane Walker) was injected with bio-organic implants which restored him to life and pefect physical health. Coltrane quickly rose in ranks and became Xerø, a fourth level Closer. Xerø later died as a result of a test organized by Decker to set Coltrane up as his own replacement. Once again Contrane was brought back to life but was severely braindamaged and of no use to the agency.
