Early career

Although a Muay Thai fighter by trade, Leuyer first began practicing martial arts at the age of five with Shotokan karate. He came to prominence in 1994 when he won the USMTA Heavyweight Championship. He then won the ISKA Intercontinental Super Heavyweight Freestyle Championship by defeating Hirawi Te Rangi of New Zealand on March 13, 1994. Later in his career, he also held the ISKA World Super Heavyweight Freestyle Championship and ISKA World Super Heavyweight Muay Thai Championship.

Invitation to K-1

In 1996, Leuyer was invited to take part in the K-1 World Grand Prix, the annual gathering of the world's best heavyweight kickboxers in Japan. Billed simply as "Jean Claude" in the promotion, he made his debut against Peter Aerts at the K-1 Grand Prix '96 Opening Battle in Yokohama on March 10, 1996. Towards the end of the first round, Aerts violently knocked Leuyer out with a right high kick.

He returned at the K-1 Grand Prix '96 in a superfight against Aerts' teammate Rene Rooze on May 6, 1996. Rooze knocked Leuyer down little over a minute into the fight before knocking him out with a flurry of punches seconds later.

His third fight in K-1 came against yet another Dutchman, the legendary Rob Kaman, at K-1 Hercules '96 on December 12, 1996 in Nagoya. Kaman, who had spent his prime years as a middleweight and light heavyweight, was in the twilight of his career and out of shape. Nonetheless, Leuyer dominated the fight before it was stopped in the fifth round due to Kaman obtaining a cut shin. Leuyer was awarded the technical knockout win.

Following this, he picked up another win over Frenchman Stephane Reveillon when he stopped him in round three at K-1 Kings '97 on March 3, 1997 in Yokohama. He then rematched Peter Aerts at K-1 Braves '97 on April 29, 1997. He was unable to take revenge, however, and was stopped in the second round.

After defeating Achille Roger on May 31, 1997 in San Jose, California, Leuyer returned to Japan to fight for the WKBA World Super Heavyweight Championship against Ray Sefo at K-1 Dream '97 on July 20, 1997. Although good friends, they put on one of the most brutal fights in K-1 history, with Sefo taking the unanimous decision after seven rounds.

He was invited back to the K-1 World GP again in 1997, but once again made it no further than the opening round as he was knocked out in round two by Australia's Sam Greco at the K-1 Grand Prix '97 1st Round on September 7, 1997.

In October 1997, he met Ray Sefo in a rematch only to suffer the same fate once more, losing a decision.

Later career

On May 24, 1998, Leuyer fought Maurice Smith for the Draka World Super Heavyweight Championship in Los Angeles, California, but the bout was ruled a draw. After this, he was invited to the K-1 USA Grand Prix '98 in Las Vegas, Nevada on August 7, 1998. He defeated karateka Tomasz Kucharzewski by TKO in the quarter-finals, only to be KO'd by Curtis Shuster in the semis.

He made a defence of his ISKA World Super Heavyweight Freestyle Championship against Andrei Dudko on May 15, 2000 in San Jose, California, stopping the challenger with a low kick in the fifth round. As the fight was entertaining and evenly-matched, a rematch was scheduled to take place in Moscow, Russia. Leuyer refused, however, and was stripped of his title.

On September 15, 2000, he was eliminated at the quarter-final stage of the K-1 USA Championships 2000 in Las Vegas, when he was TKO'd by Paul Lalonde in round two. Leuyer returned at the K-1 World Grand Prix 2001 Preliminary USA on May 5, 2001, but fared no better and was beaten on decision by Michael McDonald at the opening stage once again.

Leuyer won back his ISKA World Super Heavyweight Freestyle title on September 29, 2001 in San Jose when he defeated Jeff Ford by TKO in round eight.

His last foray into K-1 came the following year on May 3 at the K-1 World Grand Prix 2002 Preliminary USA in Las Vegas where he was defeated via unanimous decision by Dewey Cooper in the quarter-finals.

Personal life

Since his retirement from fighting, Leuyer has appeared in a number of films as an actor and stunt man, including Jet Li's Fearless. He is also a trainer at the American Kickboxing Academy.
