"Panda-Z: The Robonimation (パンダーゼット THE ROBONIMATION Pandā Zetto Za Robonimēshon?) is a Japanese anime short series created by Shuichi Oshida, considered as a parody of Go Nagai's Mazinger Z.
The series is produced by both Bee Media and Synergy Japan and began airing in Kids Station on April 12, 2004 to November 1, 2004.
Panda-Z: The Robonimation includes characters that were modeled after the main cast of Mazinger Z. None of the characters are voiced, and the show's infrequent dialogue is instead presented through intertitles. Some episodes have no dialogue at all, relying on mime movement, sound effects, and the show's electric guitar-based blues/rock/fusion soundtrack for expression. Each episode is five minutes long, including both the opening and ending credits. The ending credits also include a profile of one character or set piece from the series." (from Wikipedia)
