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?).
Detail[]
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.
