Stoker

The android free captain boss on Diaspora with his chop cycle. The crew quickly disposed of him.

Persona
Hard to say, but the man had a taste for the drugs and it cost him... everything. Called the "Rat Pirate Lord" by himself and others.

Meeting the Crew
Not really a meeting, more of a slaughter, the crew ran into him in his derelict base almost surprised. Didn't take long long for them to be defeated and his cycle.
