Pit

Pit was a prisoner in the Akritirian prison satellite.

He was a brutal bully who led a gang of prisoners who terrorized the other inmates. In 2373, Tom Paris and Harry Kim were held in the prison for a terrorist bombing that they did not commit. When Pit saw Kim, he tried to claim him, but Paris intervened. In the ensuing fight, Paris was able to stop Pit, but was stabbed by him in the process.
