Colonel Killing is a Zeon officer holding the rank of Lieutenant Colonel and the primary antagonist of the six-episode Mobile Suit Gundam: War in the Pocket OVA.
Colonel Killing was in charge of Operation Rubicon, an attempt to capture the Earth Federation's newest mobile suit, the Gundam "Alex". However, Killing deliberately sabotaged Operation Rubicon in order to gain permission to nuclear bombard Side 6. However, Killing's superior, Major General Rugens, overruled the attack, prompting Killing to murder him and and prepare the attack anyway.
Killing orders the bombardment to be at 12:00 am on Christmas Day, with the attack carried out by a fleet under the command of Colonel Von Helsing's fleet. However, Von Helsing's fleet was captured by Federation forces only a few hours before the time of the launch, foiling Killing's plan.
Though his fate is not shown in War in the Pocket it is revealed in MS ERA pictorial that, upon hearing of the death of Gihren Zabi, Killing commited suicide by shooting himself in front of Gihren's portrait.
