Tel-Tel Boy

A walking, talking cell phone from Hong Kong. He is Mantarou's debut match opponent and his weakness is water and other liquids. When he was up against Mantaro, rain devastated him and his phone lines cut off from the tournament which resulted a lead to Mantaro's victory. His name comes from teru teru bozu, a doll made from a tied up piece of cloth that ensures skies stay clear and rain doesn't fall.
