Leo is a fictional enforcer and bodyguard working for terroristic banker and Quantum associate Le Chiffre. A minor character, he appeared in the 2006 James Bond film Casino Royale and was portrayed by French actor Emmanuel Avena.
As part of his job assigned by Mr. White, Leo is tasked to help Le Chiffre to reclaim $101,206,000 due to a failed plot to sabotage an aerospace company. He is first seen entering Casino Royale with Kratt by his side as they hope that Le Chiffre would be smart to earn the winnings and get back into Mr. White's good side and return the money back to Steven Obanno.
However, this is never the case when James Bond kills Obanno and his accomplice, and he has his ally René Mathis to place the bodies on Leo's car to frame the henchman for the murders. At the police arrive to the scene, Mathis (watching the scene on a balcony with Bond) places a call, which attracts the police to open the trunk and find the bodies inside. As such, Leo is placed under arrest for the murders, much to his distraught.
Bond eventually learns that Quantum was nothing more than a front run by Ernst Stavro Blofeld of SPECTRE, and that Leo, along with Le Chiffre and White, were all pawns as part of Blofeld's true plot to wreak psychological pain on him.
- It is possible that Leo remains the sole Le Chiffre's henchman who does not die.
