Dasch was a dark-skinned man with an ocular implant for his left eye and a piece of equipment over his left ear. His usual outfit didn't include a shirt. He was the right-hand man of Wendell Carver, leader of the Screaming Skulls pirate band.
In 2502 he and the other pirates had taken over the Apollo Shipyard and took part in a plot to capture visiting ships, such as the damaged General Lee and its crew, the War Pigs. Four of the War Pigs were captured, including Cole Hickson. Carver asked Hickson to join his team, but Hickson wasn't interested. Dasch would get to "play" with Hickson if he didn't change his mind soon.
The fifth War Pig, Romy Pyrius, remained aboard the General Lee and, in a stim-fueled frenzy, killed the pirates set to board the ship. Pyrius then opened fire on the station, creating enough chaos to let the other War Pigs escaped. Dasch kept Carver updated on the deteriorating situation on the station. The remaining pirates fled to the safety of their ship, the Cutlass, with Dasch being unwilling to leave unless they fought back in some way. Carver released cybercats to kill the former prisoners. Dasch and the other pirates were killed before they could make it to the Cutlass when War Pig Nuura Joss shot out a window, subjecting them to the vacuum of space.
