Appearing in titles like Army Men: Sarge's Heroes and Army Men: Air Attack, Colonel Grimm serves as the commanding officer who issues mission briefings to Sarge and other Green soldiers. He is a dedicated leader committed to defending the Green Nation against the opposing Tan Army. His character is central to the military hierarchy and narrative progression across several games in the series.
Voice actor Jim Ward provided the character's authoritative delivery across multiple installments, establishing a distinct personality within the plastic toy aesthetic. In
Army Men Sarge's Heroes (2000) and
Army Men Sarge's Heroes 2 (2000), the character's dynamic expands beyond the battlefield through his daughter, Vikki Grimm, a reporter whose independent streaks frequently place her in danger, adding personal stakes to the military campaigns.
The character's tactical oversight extends to aerial combat divisions in
Army Men Air Attack (1999),
Army Men Air Attack 2 (2000), and
Army Men: Air Attack: Blade's Revenge (2000), where he coordinates with helicopter pilots to secure plastic battlefields. His presence in
Army Men 2 (2000) further solidified his role as a recurring anchor for the franchise's overarching lore during its peak release period at the turn of the millennium. Visually, he is represented as a gray-templed, stern-faced officer, embodying the classic mid-century military toy design that defines the aesthetic of the entire 3DO-developed series.
