The Three-Eyed One

Mitsume ga Tooru, or The Three-Eyed One, is a manga series created by Osamu Tezuka, about a gentle little bald boy called Hosuke Sharaku who happens to have a third eye hidden under a bandage, which, when revealed, brings him to a Super-Powered Evil Side. Thus, he is both the hero and the villain in his own series. He is followed around by an older girl, Chiyoko Watou, who tries to keep him in check.

Together, they investigate strange events and mysteries and will usually have to take off his bandage so he can use his high intelligence to find a solution. Of course, becoming also evil, the other characters will also have to struggle into putting the bandage back.

Sharaku is a regular of Tezuka's Star System and him and Watou often appear in other works by Tezuka, including the later Black Jack anime series (where Watou is her big sister). He usually keeps his bandage in those appearance. When without his bandage, he is a villain, such as in the video game Astro Boy Omega Factor where he is the Evil Overlord of the Mu empire.

This series includes examples of:

 * All Girls Want Bad Boys: Watou finds Sharaku more attractive when in his evil state.
 * Bald of Evil: Sharaku, without his bandage.
 * Evil Genius: This is Sharaku's main ability.
 * Meaningful Name: The names of the main characters refer to Sherlock Holmes. Sharaku is the Japanese pronounciation of "Sherlock" and Watou is often called "Watou-san", as in "Watson".
 * Shotacon: In the original manga, Watou is in love with Sharaku despite him being much younger.
 * Super-Powered Evil Side
 * Those Two Guys: Kakashi and Osamu. They fit in this trope perfectly in the anime version.
