Medabots
In the near future, humans and robots coexist. “Robattles,” a competition in which Medarot are pitted against each other, is popular among kids. A Medarot’s consciousness, effectively its brains, is located in a Medal that can be inserted into and ejected from the robot body. By chance, nine-year-old Ikki finds a Rare Medal, and soon after has his own Medarot named Metabee. This is the story of their friendship and growth as they use wisdom and courage to fight countless opponents in robot battles.
