Dōshin is a character on HBO's Westworld. He is a host in Shōgunworld. He is played by Shin Shimizu.
Dōshin was created by Lee Sizemore as a Shōgunworld counterpart to Deputy Foss. Sizemore claims he felt justified to do so, as he was under stress to create 300 new narratives in 3 weeks.
Dōshin was killed by Musashi with a sodegarami after questioning him about Yoriki Yamato.
Dōshins (同心) are samurais that perform police duties under yorikis.
