Eleonor Kliesen (エレオノーラ・クリーゼン Ereonōru Kurīzen?) commonly known as Leo (レオ Reo?) 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 Baji Quan.


Tekken 6

Prologue Text: Leo was part of a very talented family. Leo's father was a world-famous spelunker, while Leo's mother served as a G Corporation executive. Although his father disappeared during an expedition when Leo was a child, Leo still wanted to follow in the family tradition and become a spelunker. Leo possessed a strong sense of character, thanks to a proper upbringing. Life was pleasant and relatively uneventful until one fateful day, when Leo's mother was killed by an unknown assailant. Depressed and filled with grief, Leo became incensed when the police called-off their investigation quickly and without explanation. Leo vowed to find the truth. During Leo’s own investigation, the G Corporation's Kazuya Mishima materialized as a person of interest. The G Corporation was popularized at the time as a world hero, making it difficult to get close to Kazuya, and it looked as though Leo’s quest had reached an insurmountable impasse. It was at this time that news of the Mishima Zaibatsu-sponsored The King of Iron Fist Tournament began to spread. Leo learned that Kazuya Mishima was scheduled to appear in person at the event. Realizing that this may be the only chance to take revenge against Kazuya, Leo decided to enter the contest.

Ending Description: Leo pays a visit to Emma Kliesen's grave and finds a letter reading "Dear Leo." He reads it and then turns around suddenly to find no one standing behind him. The camera pans over Leo's face then points up.

Tekken 7

Prologue Text: Leo entered the King of Iron Fist Tournament in the hope of uncovering more about his deceased mother, who had been a researcher for the Mishima Zaibatsu. When Leo learned that his battle arena was to be a Zaibatsu-owned dojo, he couldn't believe his luck.

However, when he got there, the dojo was in ruins. The moonlight poured in through holes in the walls and roof, illuminating the floor with an eerie beauty. A short while later, a strange, floating silhouette appeared, and slowly glided toward Leo.

The silhouette held a sword in its left hand that rotated at a mind-bending speed. What the hell was this thing? It looked like some kind of a flying squid or octopus! Was it a demon...?

Then it finally dawned on Leo: This bizarre creature was his opponent. Cautiously, he prepared to fight.

Ending Description: After defeating Yoshimitsu, Leo ponders as to what exactly he is. Bending down, he pokes at one of his tentacles and immediately jumps back in shock when it starts to squirm. Remembering his mission, Leo bids Yoshimitsu farewell and leaves.

Ending Description: Leo is seen on a train that seems to belong to G Corporation. Leo sneaks in and reads from a computer that his mother was once a supervisor for the Mishima Zaibatsu's devil gene program. The cells of the devil gene merge together with a normal person's cells, so the Mishima Zaibatsu created a synthetic strand to use. The program was cancelled after various fatalities of the test subjects. Emma had also reported the "death" of NT01. Suddenly while Leo is saving the information onto a USB, the computer's owner arms himself and goes back into his cabin. Leo manages to get back on the train's roof only to be surrounded by three armed men. Swearing to find the murderers of his mother, Leo jumps out of the train and fires a hook that lands on the ledge.

Character Relationships


Leo is defined by a balanced gameplay. While excelling in little, Leo is good at just about everything: Leo has lots of fast, strong combos and multi-hits, stunning blows that strike high and low. Leo is also very safe, because his moves have little lag or recovery in between. Many of Leo's attacks, however, are pretty straightforward and predictable, so he is prone to be sidestepped.

Fighting Style

Leo practices Baji Quan, a Chinese martial art famous for its powerful elbow strikes, arm/fist strikes, hip checks and strikes with the shoulder, delivered with explosive, short-range power.

This style, mixed with other Chinese martial arts, is also practiced by Julia Chang and Michelle Chang. Leo, however, is the first Tekken character to practice this style alone, in its purest form.

  • Leo's gender is portrayed as ambiguous throughout the series, and many conflicting allusions have been made to their sex/gender both in and out of universe.
    • In Tekken 6, Leo's gender is not definitively given within the game, though they are referred to as a "boy" by various characters, and sorted in the "Male" section in the official artbook. They can equip gender-specific items, such as a sledgehammer (which is a male item) and pigtail hair bases (female item). Leo cannot be attacked by Anna's Slap Happy (b+2), which is usable against females; but by Heihachi's Headbutt Carnival (f,F+1+4), which is usable against males. Their continue and next round animations are those of male characters.
    • In Tekken Tag Tournament 2, Leo has a female sex and can equip revealing female items such as bikinis and swimsuits, though they remain able to equip male-exclusive items.
    • In Tekken 7, Leo is referred to by male pronouns and is sorted amongst the male characters. Allusions are made by many characters to Leo being unusually "pretty" or "beautiful" for a man.
    • Katsuhiro Harada previously referred to Leo as female, once at the Cologne premiere of Tekken: Blood Vengeance[1] and again at an event for Tekken Tag Tournament 2. Years later, however, Harada changed his stance, stating that Leo's gender was only female during the character's initial conception and that as of the current time, their gender is officially unknown[2].
    • In all titles, Leo can equip both male and female items, regardless of the gender they are referred to.

Tekken 6:

Tekken Tag Tournament 2:

  • Leo has the largest hitbox of all human female characters, being Class 3 in Tekken Tag Tournament 2. Ling Xiaoyu, Jaycee and Alisa Bosconovitch are Class 1, every other female in Class 2.
  • Leo now speaks her native language, German. As her voice actress appear either masculine or a tomboyish pitch.
  • Leo can be customized to look like Sora & Roxas from the Kingdom Hearts series, Tenten from the Naruto series, Eliot from Dead or Alive 4, & Indiana Jones.

Tekken 7 and Tekken 7: Fated Retribution:

  • Leo is unable to wear both the Officer's Cap and the Slim-Fit Military Top at the same time. This is likely to avoid Nazi symbolism.
  • In both Yoshimitsu and Leo's endings from the titular game Leo briefly speaks English, but continues to speak in German through the rest of the game.
