The gender of Leo has been brought to question over the past several game. While Harada has confirmed the character to be female during the Cologne premiere of Tekken: Blood Vengeance, in game Leo is almost always referred in gender-neutral terms. It has also been confirmed that Leo's full name is Eleanor Kilesen and was given a bikini costume in Tekken Tag Tournament 2. This all changed in Tekken 7 when Leo was officially referred to as a male through both Yoshimitsu's and Leo's bio page.
