When Nae discovers Metabees new parts are incompatible with his tin-pet, she offers to repair them on the condition that Ikki and Metabee promise not to robattle until she finishes. Our heroes manage to resist the challenges of Kam until he viciously begins to destroy innocent Medabots with his kilobot, Tankbank. Ikki and Metabee robattle Tankbank to a draw, allowing Nae to complete her work. Once the new parts are refitted, Metabee easily destroys Tankbank.
