Seaman, called Seaman: Kindan no Pet (シーマン 〜禁断のペット〜) in Japan, is a video game developed by Vivarium for the Sega Dreamcast in 1999. It debuted with the Dreamcast Microphone, which was bundled with the game. The game was not released in Europe (plans were once in place to release it there in 2001), though the Microphone accessory was (Planet Ring being the only game released in that region to be compatible with the peripheral). The game was later ported to the PlayStation 2 in 2001.

Japanese consumers also had an option to buy a "Special Package" bundle, which as well as including the game and microphone, also included a clear VMU (as the game requires one to function).



Upon release, Seaman became the best-selling Dreamcast game in Japan, beating Sonic Adventure and SoulCalibur[1].

Sequels/updates Christmas Seaman and Seaman 2001 were released in Japan, and the game was also followed by a PlayStation 2 sequel, Seaman 2.
