This match takes place in Star Wars universe.
Two of the greatest mechs in Pilerverse have been ported onto the surface of the Death Star just as the Battle of Yavin begins. The Rebel Alliance has deployed its assault squadrons, but they have not yet cleared the gas giant to have the battle station in their sights.
Lion Force Voltron has been ported to the north pole of the Death Star, while Great Mazinger has been ported to the south. Both mechs have a directive to eliminate the other without interfering with the battle, but can and will defend themselves if they come under attack. The empire considers both mechs to be rebel secret weapons, but will cease fire against them as soon as the mechs begin doing battle. The rebels see the mechs as a great boon to their assault and will leave them well enough alone.
NOTE: Vader, Luke, Solo, and any other key character is protected by P.I.S. to fulfill their tasks as seen in the movie and related Star Wars publications. The mech battle will not interfere with those elements in any way, and their battle will not be interrupted by those in turn.
Will one mech come out victorious? Will either, or both, get destroyed by the Death Star’s defenses? Or will both get blown to bits with Luke’s auspicious torpedo launch?
