Kul Teska was a Skakoan male mercenary active during the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems. Before he took a criminal's path, Teska was a respected scientist in the Techno Union. However, an accident with his pressure suit left Teska disfigured and forced him to leave the Union. With the help of his knowledge in the field of cybernetics, Teska rebuilt his pressure suit, equipping it with a variety of weapons, and became a gun-for-hire.
