Mothra: The author doesn't own anything from either the Godzilla or Ultraman franchises. Godzilla belongs to Toho & Ultraman belongs to Tsuburaya.
Ultraman: Also Mothra will look like her Rebirth of Mothra 1 incarnation. But this happens long after that.
Chapter 1 The Creation
Summary: Belial travels to a plagued world & gets inspired to make the ultimate weapon.
Belial: Thank goodness the author doesn't own anything from the Ultraman franchise or the Godzilla franchise.
It was over 20 years after Belial was defeated for the second time. He had become a distant memory. Although he was defeated, Belial wasn't killed. He was flying through the universe, trying to find another weapon to destroy Zero. He came close the last time with his mega-monster Beryodora & almost had him with Arch Belial. Then Belial heard some pained cries. He followed the sound to a distant planet. He went through the atmosphere & found a dying world. Plants lay withered, creature's skeletons were shivering, the sounds for help were echoing in the wind. "What a dump! It looks like something swept through- Here…. Something powerful..." Belial said. A large smirk made its way across his face. He gathered some of the dying plants, pick up the skeleton of an unknown creature, collected a sample of the soil & flew off with the items.
Nearby a black hole…
Belial was mixing the ingredients together with a small sample of the Plasma Spark he got on his last attack. "Perfect… Now for a pinch of Plasma..." Belial mumbled. He then flung the mixture into the black hole. It worked like a giant blender. Then Belial flew in & re-captured the mixture. It was now a gum-like substance, but it was something more. Belial's Ultra-Vision showed him something that was hungry. "Now to enact my revenge..." Belial thought.
Belial: Well that's a dull start! R & R!
