Great Titan

A second robot created by the union of the Titan Boy and the trailer unit of the Flash Titan. When the command "Flash Turn! Great Titan!" is given, the rear of the trailer becomes the legs, and the front part reveals the head (which the head becomes a part of the Titan Boy) and arms, as the wind defector swings out to become the chest. It destroys monsters with its ultimate finishing attack, the Titan Nova (タイタンノバ, Taitan Noba).
