Mechanical Dragons Fifty years after a nuclear war nearly destroyed the human race, the war has been abolished and territorial disputes between the two superpowers are settled by warriors fighting one-on-one in giant robots called "Mecha Dragons".　The allied robot warrior Alexander has killed nine of the Combine's robot warriors in quick succession, and the Combine has no choice but to fight the next battle for Alaska.　This time it will be Achilles, a robot warrior from the Combined Kingdom, who will face Alexander.　However, the traitor has already leaked the design drawings of the Hopitalia's robot to the Allies.　This final battle is not only for the country, but also for the personal grudge ...... In the twenty-sixth century, robots had become popular. People were keen to watch large human-operated robots fight live, and to sign life-and-death pacts for this purpose (if there was an accident in the match, the responsibility would be borne by the individual). One of them was a man who won many battles and won great honor. However, just as he is about to win, he accidentally loses a match to his opponent (who is playing a dirty trick). The giant robot collapsed and crushed the audience behind him, and many people were crushed alive before they could escape. He climbed out of the control cabin with a bloodied face and saw the disappointment in people's eyes. From then on he was devastated, believing that he had killed innocent spectators, and stopped competing. Instead, his rival took his place for good. Later, in order to oppose his rival's evil plan, he was forced to fight again, and he proposed that there be no spectators in order to avoid hurting innocent people, and his rival agreed (his rival was controlling a spider robot). During their duel, the robot he controls is cut off by his opponent with a hidden weapon, a chainsaw, and he controls the robot to fly to another planet, and his opponent comes after him. In order to keep his balance, he merges the legs of the machine into a disc-like propeller, and he drills through the enemy's pants and traumatizes his opponent once more. But his opponent also scrapped his mount ---- cutting his control pod with a chainsaw and severing one of the machine's hands. He fled in a panic and hid behind that machine hand, and amidst the hideous laughter of his opponent and the sound of his approaching footsteps, he quickly connected the circuits of that hand, and just as his opponent was about to put the chainsaw down, he suddenly let go of it, and the hand flew straight toward his opponent's cockpit, and his opponent's big spider was scrapped. Then they had their final battle on that desolate planet with their bare hands.
