A sexual complex similar to that of the Lolita Complex.

The Shotaro Complex describes a sexual attraction to younger boys, usually by adult males. However, females may also have this complex.

It is named for the boy hero of Tetsujin 28-Go (also known as Gigantor), which is also a popular generic name for young male characters in anime.

The Shotaro Complex is often shortened to shotacon.
Those with the Shotaro Complex like boys who are precocious in nature.
