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. The face of this particular Rodan also appears to have a droopy-like look to it.
SoshingekiRado is one of the most neglected Rodan suits by fan standards. Till this day, many fans discuss about this Rodan being a suit favorite, because due to it's weird looking appearance (close-up included), most fans call this Rodan suit one of the most degrading suits compared to other Rodan suits.
