Metabee

Metabee (whose name is a portmanteau of Metal Beetle) is a Medarot belonging to Ikki Tenryou. Metabee is a beetle type Medarot, specialising in revolver tactics. He possesses a rare medal that allows him to access the Medaforce. Metabee is known to be quite aggressive and stubborn, and often causes problems due to his headstrong personality. He is often disobedient to his owner Ikki, but he shares a close bond with him, and so Ikki trusts him deeply.
