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 Shōgunworld's 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.
