Season 2

Fragments of a mysterious stone known as the Skull Stone are scattered across the globe. Once all four pieces are assembled, the location to the world's largest deposit of gold will be revealed. The villainous Doronbo Gang are searching for the Skull Stone. Standing in their way are Gan and Ai who become the masked heroes Yatterman-1 and Yatterman-2. The two are aided in their adventures by a large mechanical dog Yatterwan. Unlike previous series in the Time Bokan franchise, Yatterman does not cover any specific time/space travel. Instead, the places where the hero travel to and the individuals they encounter are either a homage or parody. The fictional characters or places are usually represented by purposely misspelled names or familiar actions. For example, a revolution leader is named "Yashington" as a homage to George Washington; and a place resembling ancient Japan is named "Yametai" ((I) want to stop), as a spoof of Yamatai.
