Ikki and Metabee have defeated the Rubberobo Gang once and for all and have earned their place on the Japan World Robattle team. But when Erika sights a UFO, it turns out the aliens aboard are really the Rubberobo Gang. Have they been aliens all along?
Then Metabee finds a lost Mermaid Medal and the search is on for its owner and its body. Things get stranger still when Samantha falls in love, and Erika and Brass help her try to win the man of her dreams. A trip to Ninja World where the Rubberobo Gang is kidnapping Medabots doesn't help straighten things out. Will the last straw be a massive Medafighter looking for the Medabot that ambushed him and eating Ikki and his parents out of house of home in the meantime?
