 Publishers of "shōnen" manga may create "homoerotic-themed" merchandise as fan service to their BL fans.Comiket's co-founder Yoshihiro Yonezawa described "dōjinshi" as akin to "girls playing with dolls"; "yaoi" fans may ship any male-male pairing, sometimes pairing off a favourite character, or creating a story about two original male characters and incorporating established characters into the story.Any male character may become the subject of a "yaoi" "dōjinshi", including characters from non-manga titles such as "Harry Potter" or "The Lord of the Rings", video games such as "Kingdom Hearts" "Overwatch" and "Final Fantasy", or real people such as politicians.
