Panda-Z: The Robonimation (パンダーゼット THE ROBONIMATION) is a Japanese anime television series. The show features a number of giant robots piloted by anthropomorphic animals, in a parody of super robot shows such as Mazinger Z that were popular in the 1970s.
None of the characters are voiced by seiyū so the show's infrequent dialogue is instead presented through intertitles. Some episodes have no dialogue at all, relying on mime, sound effects and the show's electric guitar soundtrack. Each episode is five minutes long. (Wikipedia)
