Alcar was a Scarran soldier who was sent to Dam-Ba-Da ahead of a Scarran Dreadnought. When he arrived, he discovered the blinded Talyn orbiting the planet and boarded him, easily subduing Bialar Crais and Stark for control of the gunship. He was interested in procuring the vessel for the Scarran Empire, and so ordered Crais to construct a neural transponder for him. Crais rigged the transponder to root the Scarran in place, and while the "Hand of Friendship" was holding Alcar the ship's internal security turrets, killing him.
Alcar is a character from the third season of Farscape.
