In some English versions, Sharaku's name has been "anglicized" to "Shallack".
Hosuke Sharaku is also part of Osamu Tezuka's Star System.
The character may have been the inspiration for the manga 3×3 Eyes.
To protect mankind from his terrible power, Sharaku is made to wear a bandage which seals his third eye. While his eye is sealed, Sharaku knows nothing of his true nature or his power, and does not remember his evil half's sinister attempts to conquer the world. Sharaku is helped and nurtured by a young woman, Wato Chiyoko (和登千代子), who is drawn to the evil charisma of the Three-Eyed One.
He appears as the main villain of the Game Boy Advance game Astro Boy: Omega Factor, where he is the cruel prince of the Mu empire who confronts Astro Boy. His presence in the game is based on the old Tezuka series Marine Express.
He alkso makes several appearances in Black Jack, most noticeably in the recent TV animated adaptation, in which he's a normal junior high schooler and has a huge one-sided crush on Black Jack's assistant Pinoko. Also, instead of his warden, Chiyoko Wato is his older sister and a kendo practitioner of national level.
