«Howzer» was a clone who served as a stormtrooper captain in the Imperial Army of the Galactic Empire shortly after its formation in 19 BBY. Stationed on the planet Ryloth, he worked with Senator Orn Free Taa and the former Twi’lek Resistance leader General Cham Syndulla to help maintain peace on the planet. Howzer stood with Syndulla when he implored the former resistance members to trust the Empire’s protection. Later, the captain returned Cham’s daughter, Hera Syndulla, to the general after she was caught trespassing, choosing not to report the incident.

After Hera and two Twi’lek Resistance fighters were caught smuggling weapons, Howzer arrived after their arrest and helped oversee their transportation. However, Cham and some other Twi’lek militants intercepted their Juggernaut to rescue their comrades. They defeated Howzer’s forces and held the captain and his colleagues, Vice Admiral Rampart and Senator Taa, captive. Howzer advised against Cham killing Taa before Imperial reinforcements arrived and captured the Twi’leks excluding Hera. Rampart thus ordered the captain to find Hera.
