Biography
Raiker was a sub-commander in the Terran Federation prison service and the first officer of the Civil Administration Ship London. He was a brutal sadist who enjoyed the power he held over the prisoners, who his ship transported to the penal colony on Cygnus Alpha. On giving them their induction, he told them "There are other rules, but you'll find out what they are when you break them." He had a reputation for taking advantage of the female prisoners, willing or otherwise. When Jenna rejected his initial attempt to charm her, he struck her and told her she'd come to him sooner or later. He also took pleasure in having the famous Roj Blake in his charge, insisting he call him "sir".

When an attempted break-out by the prisoner resulted in most of them being quickly recaptured but Blake, Jenna and Avon having control of the ship, Raiker informed Blake he would shoot one of the other prisoners every thirty seconds until he surrendered. He killed two before receiving the news Blake had given in, then killed a third anyway. He then tried to have Jenna sent to his quarters, forcing his commander, Leylan, to step in.

When the London discovered the Liberator derelict in space, both Leylan and Raiker were keen to salvage it for prize money. An initial attempt at boarding left two crewmembers dead and a third driven insane. Leylan wanted to abandon the plan but Raiker convinced him to send Blake, Jenna and Avon across, convincing them to "volunteer" by threatening them with summary execution. After the trio had secured the ship, Raiker attempted to cross the transfer tube connecting the two ships. He saw Blake trying to seal the hatch and shot at and wounded him. Moments later, the Liberator detached from the tube and Raiker was blown out into space and killed.
