Appearing in Katsuhiro Otomo's animated short "Cannon Fodder," Father serves as an artillery crewman within a city consumed by perpetual warfare. Towering cannons dominate the skyline; daily existence revolves entirely around firing upon an unseen enemy. This occupation defines Father's life. He operates and maintains the massive artillery pieces alongside his wife, the unit's gunner, forming a familial unit within the militarized society.

Their son accompanies Father to work, witnessing the precise routine of cannon maintenance, shell loading, and the firing sequence. Father executes his duties with mechanical expertise, demonstrating deep familiarity with the artillery machinery. During a brief lunch break perched on the cannon's exterior, he shares a practical interaction with his son but pointedly avoids answering the boy's question concerning the enemy's identity and location.

Father functions purely as a component within the vast war machine. His family life is fully integrated into the military apparatus, their home situated within the cannon structure itself. The narrative depicts no personal history, background details, or character development beyond this single day, offering no insight into his thoughts, motivations, or any potential change in perspective.
