Sergei and his commandos arrived in Japan to kill Kawamata for stealing one of Russia’s combat suits. Meanwhile, Kawamata’s limbs were replaced by the government. In addition, he began to feel sick and tired of fighting for the government and chose Iba as his successor to the combat suit. Sergei arrived at Kawamata’s home and successfully killed him despite Iba’s attempts to protect his mentor. Suddenly, another meteor appeared and was secured by Sergei’s commandoes, but in a freak accident, the meteor thawed from its confinement and the ooze infected Sergei turning him into the Combat Suit Monster and went on a rampage and ate the other commandos. Now it was up to Iba to fight this beast. The end of the movie ended in a cliffhanger, where Kawamata’s brain is preserved for study; further denying him any peace even after death.
