Leo Kliesen is a character that first appeared in Tekken 6 and is slated to appear in upcoming Tekken Tag Tournament 2 installment. Leo made her first appearance in the official Tekken 6 trailer battling Armor King. Leo is an orphan who lost her parents under the circumstances that police would not want to investigate. Leo play style is also intended for beginners and veterans alike. Leo's fighting style is Bajiquan.


Leo's parents were a famous male spelunker and a top female executive of the biotech firm, G Corporation.

Leo’s father disappeared during an exploration when Leo was a child, but even so, Leo tried to be just him. Leo grew up to be a straight and narrow person, but Leo's mother's murder changed everything.

Saddened by the tragic event, Leo shut everyone out. Some time later, the police inconclusively ended the murder investigation without explanation but Leo continued to try to crack the case. Not long after starting this mission, Leo discovered the existence of a person regarded as a hero of the G Corporation - a man by the name of Kazuya Mishima. Suspecting him of committing the murder, Leo sought revenge but found it impossible to get near Kazuya due to his newly acquired status within the G Corporation.

However, Leo heard news of The King of Iron Fist Tournament 6 being held by the Mishima Financial Group. Finding out that Kazuya would be participating in it, Leo signed up, thinking that it would be the only chance for revenge. 

Tekken 6  

Leo's closing cinematic takes place at the grave of the character's mother, where Leo finds an envelope labeled with "Dear Leo," and then quickly turns around to find that no one is in sight. 
The gender of Leo is not exactly left open to te viewer. The character is voiced by a female and female hair sets are available in character customizations indicating that the character could be female yet is found in the male section of the Tekken 6 Art Book therefore indicating that the character is male. Upon question Namco said that they wanted a character who could be loved by the public no matter what their gender. It was assumed that the character was 12 years old until Namco confirmed the character was 19. 
Tekken 6: Bloodline Rebellion 
Leo remains unchanged mainly in variants of the game. However in Bloodline Rebellion Leo's item move was changed, in Tekken 6 the move is to fire a flare into the air with a pistol whereas in Bloodline Rebellion the move was changed to hitting the opponent with a mace.


  • Leo's gender is left ambiguous by Namco. Leo could be customized with female hairstyle yet is placed in the male section of the Tekken art book.
  • Leo's surname, which is probably "Kliesen" is revealed in the power is everything trailer. It is shown on her mother's grave.
  • Leo is voiced by Veronica Taylor, the same person who voices Ash Ketchum in the Pokemon series.
  • It is unknown whether Leo's father is dead or not. It is only mentioned that he disappeared in one of his explorations. 
  • Under the eagle of Leo's parka you can read 'Die Lebensspanne ist dieselbe egal ob man sie lachend oder weinend verbingt' (The lifespan is the same, whether it is spent laughing or crying), which is a Chinese wise saying.    
  • Joined the Tekken 6 tournament to hunt Kazuya Mishima.
