Prototyped before the Second Tiberium War (first units were deployed as early as 2034, during the Rio Insurrection), Marcion's writings state that he himself created the design, attributing Kane with inspiring him to do so. The tank, codenamed the Scorpion, has three unique design features - first, the front of the tank is sloped, with the back completely exposed. Second, the gun is mounted on the front right next to the crew compartment. Third, it moves on three threads.
