The available sources on the *Ghost in the Shell* franchise contain no direct references to a distinct character named "Tachikoma C" in *Ghost in the Shell: SAC_2045* or other official media. Documentation describes the Tachikomas comprehensively as a collective: nine AI-driven vehicles with synchronized memories, deployed by Section 9 across *Stand Alone Complex*, *2nd GIG*, and *Solid State Society*. These units occasionally exhibit individualized traits in *Stand Alone Complex*, such as Batou's preferred unit, a more logical unit, a slower unit, and a bookish unit—though none carry alphabetical designations. *SAC_2045* confirms their return in physical bodies, still without unique identifiers like "C". No sources attribute specific background, development, or traits to a "Tachikoma C" unit.
