Leo kliesen

Leo Kliesen (レオ, Reo) (born April 14, 1988) is a character in the Tekken fighting game series. Leo is one of the four characters first introduced in Tekken 6, which was released to Arcades in Japan on November 26th 2007.  Leo is from Germany, and fights with the art of Hakkyoku-ken (Bajiquan).

There were rumors before the game was officially released that Leo was a girl, and shortly after the game was released in Europe, there were complaints about the character most likely because he was thought of as a transgendered character; in game, Leo is referred to only by name or gender-neutral terms, and he has no costumes that reveal any portion of the torso, which would normally make the character's gender clear.

Leo has no official gender. The Bandai-Namco development team had stated that they wanted to create a character that would be loved by fans regardless of gender so they made the gender of Leo ambiguous on purpose.
