Yattodetaman (ヤットデタマン) is the fifth installment in the Time Bokan series, produced by Tatsunoko Production and directed by Hiroshi Sasagawa.

In order to secure the Kingdom, two representatives go back in time to find the mythical Firebird, which will allow its bearer to become the rightful ruler.

However, a major technicality prevents Kamaro from succeeding with his plan, because whoever finds the mystic Firebird first will become the new and rightful monarch.

The Firebird travels throughout time and space in the past, disguised as mystic objects of legends, and the evil villains want to capture it.

The honorable daughter of the deceased king, Princess Karen, and her guard-robot, Daigoron, travel towards 1981 to ask for help from his ancestors, Wataru Toki and Koyomu Himekuri, in locating the Firebird.
