This massive box set contains rhinoceros-form SaiDain along with a 28cm-long SouJyuuTou! Summon the great rhinoceros Geki Beast with SouJyuuTou and bring forth SaiDain, which can transform into the heavily armored, all-powerful SaiDaiOh! Start and stop the forward movement of the toy by placing the SouJyuuTou over the red orb located on the back of both forms. Combine SaiDain with Geki Wolf and either Geki Touja or Geki Fire, all linked below, to form SaiDai Geki Touja and SaiDai Geki Fire respectively for the ultimate combination finishing move! Two C alkaline batteries are required, not included.
