The SoshingekiRado's name comes from the film's Japanese title, specifically sōshingeki (総進撃?), meaning attack of the marching [monsters], and Rado, which comes from Rodan's Japanese name, Radon (ラドン?).
Though similar in appearance to its predecessors, ShodaiRado and SanDaikaijuRado, the SoshingekiRado suit has slightly longer horns. The wings appears to be longer and more pteranodon-like, and the beak is longer and pointed downwards. The face of this particular Rodan also appears to have a droopy-like look to it.
