Blaster Master Zero
One day, a young man named Jason Frudnick, known for being a genius in the field of robotic engineering, discovered a strange creature that he had never seen before. No records of this mysterious creature could be found, so Jason gave it the name " Fred " and took it to his lab to begin closely observing it.
Shortly after that, an accident occurred in the lab and Fred managed to escape. Fred jumped into a hole that seemingly appeared out of nowhere. Jason followed, and before he knew it, he found himself in a cave where the battle vehicle " SOPHIA III " awaited him.
With his curiosity in this incredibly high-tech vehicle piqued, Jason hopped abroad SOPHIA III and began his adventure in the vast subterranean world in search of Fred.
