Officer Kobrin was a Peacekeeper pilot under Scorpius' command. His skills were exceptional, having scored a 991 rating, the highest of all active Peacekeeper pilots. This caused Kobrin to get a sense of arrogance about his considerable abilities, something that would eventually lead to his undoing. When Scorpius and Lt. Braca led a small group of soldiers to an ice planet to recover a neuro-chip from the brain of John Crichton, it was Kobrin who piloted a Marauder in on a stealth trajectory, slipping past the gunship Talyn while it was distracted.
