As a result of the battle against the 31 Machine Primevals, the warriors of the Red Planet are flung to the The Void at end of the universe. There, they encounter J-Battler, a silver ship of the same model as J-Ark. Giant Mechanoid vs. Giant Mechanoid! Who will win this showdown of the century?! (Source: Firecross, translated)
