Harlock's first mate on the Arcadia, he is usually portrayed as comic relief in the series, but when a battle against alien threats become imminent he will be at the captain's side. He is also a brilliant mathematician and has a major interest in building plastic model kits of ships (he was even seen building a scale model of the Arcadia in one episode). Yattaran is based on manga artist Kaoru Shintani (best known for Area 88) who, in his early career worked for Matsumoto building models for reference. (Source: Wikipedia)
