Zamsher

Far away from earth, on a meteor with green flames around it, two warriors battled fiercly: An Alien Magma, and a mysterious swordsman in armor, known as Zamshaa. A second Alien Magma came to aid the first in battle, but the first was ultimitely killed by Zamshaa, leaving the second to fight alone. Later, as the meteor approached earth, Zamshaa finally destroyed the second Alien Magma by using a slicing move that split him, as well the the meteor, in half. He then climbed aboard a lone meteorite, but was soon greeted by another; Alien Valkie, who was on a meteorite as well. But instead of fighting, the two lept from their meteorites and prepared to land on earth; their new battlefield. Mirai went to investigate, but both passed him up, and eventualy landed on earth, ready to fight. Alien Valkie, however, was no match for Zamshaa, and who stabbed him in the back, and watched as he fell to the ground, as he blew up. Mirai soon returned to earth, and both had long conversation, before Mirai decided to turn into Ultraman Mebius. The two fought with their swords, but Mebius's was sliced in half quickly. But Serizawa, who was in the area, turned into Ultraman Hikari, and, with one quick slash, destroyed Zamshaa's sword. Beaten, Zamshaa decided to leave. He walked into the sunraise, and disappeared. Zamshaa would return months later after Ultraman Hikari discovered what Alien Empera was doing to Earth's sun as it was being consumed by darkness. Zamshaa reappeared on Eart and quickly destroyed a Mass Production Imperializer right before it would destroy GUYS' base. With him was Alien Psychokino and Alien Fantomn in GUYS' base. After destroying the robot the Mass Production Imperializer went into the atmosphere. Shortly after Alien Empera made his appearence. With little effort the fiend surrounded the planet in darkness. Zamshaa, Psychokino, and soon arriving to the scene Hikari could not so much as touch Enpera as his dark shockwaves were more than the heroes could handle. Zamshaa sacrificed himself before Empera could finish off GUYS, giving his allies another chance to fight.==Ultraman Mebius Side Story: Ghost Rebirth==
