Grievance Striker

The "Grievance Striker," also known as the "Annihilator," was a custom DT-57 "Annihilator" blaster owned by General Grievous, the Supreme Commander of the Separatist Droid Army during the Clone Wars. During the battle of Utapau, Jedi General Obi-Wan Kenobi shot Grievous with the Grievance Striker, ironically killing the cyborg owner and general with his own weapon.
