Early K-1 career, World GP wins in 2003 and 2004

Bonjasky had his first fight at the age of 19 against Valentijn Overeem. Bonjasky won by TKO. From this moment on he quit his job as a network operator and focused on training full-time. Despite losing his first K-1 fight by split decision he made his second fight against an established K-1 fighter, Ray Sefo, winning by TKO.

Bonjasky lost against K-1 and kickboxing superstar Stefan Leko in 2002.

On December 6, 2003 at the K-1 World Grand Prix 2003 quarter-finals in Tokyo, Japan, Bonjasky was matched up against Australian fighter Peter "The Chief" Graham. Remy won the fight by a TKO in the first round. In semi-finals Cyril Abidi fell victim of The Flying Gentleman's flying knee attacks, and after defeating Musashi in the tournament finals by unanimous decision Bonjasky was crowned the K-1 World champion.

In 2004 he accumulated wins over Tsuyoshi Nakasako, Francois Botha, Aziz Khattou and ex-sumo champion Chad "Akebono" Rowan. If it hadn't been for his one loss in 2004 against Francisco Filho he would have beaten Semmy Schilt's record of the longest winning streak in K-1 history.

On December 4, 2004 at the K-1 World Grand Prix 2004, with three decision wins over Ernesto Hoost, Francois Botha and Musashi, Bonjasky successfully defended his K-1 WGP title.

He presented himself on November 19, 2005 for the K-1 World Grand Prix 2005 finals in Tokyo, to keep his title for a third consecutive year, but was stopped by Semmy Schilt's knee strikes in the tournament's semi-finals.

2006-2007: Feud with Leko, World GP misfortunes

In 2006, after his divorce and change of trainers, he came back to the K-1 World Grand Prix 2006 finals. In his quarter-final match, he got a rematch against former foe Stefan Leko, who'd beaten him in 2002, and it turned into a grudge match. When Bonjasky was champion, Leko was taking a hiatus away from K-1, and his career rise had thus stalled. Prior to his rematch with Remy, he pledged that the 2006 Grand Prix would be his year to finally become the undisputed champion, at the expense of Bonjasky whom he'd beaten before. Bonjasky stated that Leko was 'limited'. In the fight, Bonjasky got hit in the groin twice in the first round and the fight was postponed for 30 minutes. When the bout resumed, Bonjasky still managed to win the fight by a unanimous decision, after scoring a knockdown in the final minute of the fight. However, because of a persisting injury to the groin, he was not able to continue the tournament and was replaced by Peter Aerts.

In 2007 Bonjasky's mother died. Because Remy was badly hurt by this he pulled out of scheduled fights with Badr Hari and Peter Aerts. His only fight before the final 16 was against Glaube Feitosa in Hawaii. Remy won by decision and remained open for the final 16 event.

On September 29, 2007 Bonjasky was booked in a rubber match with Stefan Leko at the K-1 World GP 2007 in Seoul Final 16 event. The pair went in with bad blood, as Remy claimed that simply hearing the name of Leko 'made his blood boil' after their second fight, and he claimed that the groin shots he delivered were deliberate. He further lit the fuse by claiming Leko was a limited fighter, who 'only had a couple of punches and a spinning back kick, nothing else'. Leko for his part said he would be glad to prove once and for all that he was the superior fighter, which he claimed was clear from their first fight, and that Remy was 'an actor', and had been 'lucky' the second fight, and had 'the heart of a chicken'.

Bonjasky won the grudge fight by TKO when the ref stopped it in the first round after landing his trademark flying knee strike. Leko beat the count, but the referee waved off the bout. Some have criticised the stoppage as K-1 protecting the by-then bigger name superstar, as Remy had been their World Grand Prix champion, and that K-1 wanted him through to the later stages. Others said that Leko did not display that he still had his faculties. Regardless, the fight marked the end (as of 2011) of the feud between the two, and the win qualified Bonjasky for the K-1 World Grand Prix 2007 Finals which were held on December 8, 2007 at the Yokohama Arena in Japan.^[10]

At the K-1 World Grand Prix 2007 Finals, Remy Bonjasky faced fellow Dutch fighter Badr Hari. He won the fight by decision. In the semi-finals he faced Dutch legend Peter Aerts, losing to Aerts in a unanimous decision.

Return to the top, World GP 2008 champion, later career

Bonjasky started off 2008 by knocking out Melvin Manhoef in Amsterdam, Bazigit Atajev in Tapei and majority decision over Paul Slowinski in the K-1 16 to qualify for his 6th Grand Prix appearance.

Winning the 2008 K-1 World title

In the quarter-finals he defeated Jerome Lebanner by TKO, Gokhan Saki by KO in the semi-finals, sending him to the K-1 World Grand Prix Finals for the third time against Badr Hari. After a slow start he knocked Hari down with a left hook and then went on defensive for the rest of the round. Remy was hit after the bell at the end of the round by an angry Hari. In the second round Hari took Remy to ground, then punched him twice and then gave an unsportsmanlike foot stomp to Remy when he was down. Remy seemed unable to get up and was inspected by the ringside doctors. Meanwhile, Hari screamed at Remy, telling him to get up and quarrelled with his trainer, Ivan Hippolyte. After 5 minutes the doctors announced Remy had double vision and could not continue. Hari was therefore disqualified and Bonjasky was declared the K-1 World Grand Prix 2008 Champion. Remy was disappointed by the outcome, evident from his unhappy expression after the decision was announced.

Bonjasky stated in a post-fight interview that he still had double vision and a headache the next morning.^[11] Hari however claimed that "Remy was acting", and that, "his corner was screaming at him to stay down".^[12]

After he won his 3rd GP title, he faced Alistair Overeem. Overeem was aggressive in the 1st and dominant in the 2nd round, knocking Bonjasky down in the end of the 2nd round with a right cross, but referee Nobuaki Kakuda did not count it. In the 3rd round Remy knocked Alistair down with a flying knee and right punch combo to secure a unanimous decision win. All three judges scored the bout 30-28. It was later confirmed that Remy had badly twisted his left knee 2 days before the fight (reason for his inactivity). Remy went on medical recovery after the fight and did not fight again for months.

Remy returned to training to train for the K-1 World Grand Prix 2009 Final 16. At the event he defeated Melvin Manhoef, for the third time, by unanimous decision.

At the K-1 World Grand Prix 2009 Final Remy was won his third consecutive unanimous decision against Errol Zimmerman. In the semi-finals he met his nemesis Semmy Schilt. In the first round Remy landed a left hook to knock Semmy down. Semmy however landed a low kick to Remy's left leg that was damaged in his earlier fight with Zimmerman, Remy was therefore knocked out of the tournament, losing to Semmy for the third time.

Bonjasky was absent from the K-1 World Grand Prix 2010 in Yokohama tournament,^[13] and did not fight at all in 2010, and has pondered retirement after having eye surgery in August of the year.^[14] He opened his own kickboxing / muaythai gym, Bonjasky Academy, in the city of Almere in that year.^[15]

Comeback

After three years out of the ring due to an eye injury, Bonjasky faced Anderson "Braddock" Silva at Glory 2: Brussels on October 6, 2012 in Brussels, Belgium.^[16] After a close three rounds, the bout was called a draw and went into an extension round. Silva faded and allowed Bonjasky to get the better of him, coming out as the majority decision winner.^[17][18]

He competed in the sixteen-man 2012 Glory Heavyweight Grand Slam at Glory 4: Tokyo - 2012 Heavyweight Grand Slam in Saitama, Japan on December 31, 2012. At the opening stage, he defeated Filip Verlinden by unanimous decision, taking rounds one and three. He was then eliminated in the quarter-finals, however, when he looked lackluster against newcomer Jamal Ben Saddik and, due to the "best of three" format in the tournament, lost on points after two rounds.^[19][20]

He faced Tyrone Spong at Glory 5: London in London, England on March 23, 2013.^{[21][22][23][24]} Bonjasky lost in the second round via KO from a right hook.^[25][26][27]

In July 2017, he announced another comeback via Instagram, stating that he signed a contract with Glory kickboxing.^[34] Later that year it was announced that he would face Melvin Manhoef for the fourth time. The fight was not promoted by Glory but instead World Fighting League, a promotion founded by Melvin Manhoef, promoted the fight. The bout took place in Almere, Netherlands on October 29, 2017. Bonjasky lost the bout by decision. After the bout he announced his retirement.^[35]

Medal of honor

Bonjasky has been awarded two medals of honor since 2007.

Near the end of July 2007 in Amsterdam, he helped Dutch police in the arrest of two British criminals. The two men had shot darts at passers-by with a rifle while they were on the move in a van. Bonjasky was their last victim, and after having been hit by the dart he pursued the van in a cab and proceeded to call the police who managed to arrest the criminals.^[41] Following the arrest, Bonjasky received a medal from the Amsterdam Police Department for this courageous and honorable act.^[42]

In 2009 he was awarded the medal of honor by the city of Almere, becoming an honorary citizen of the city, after being chosen by the city's politician Arno Visser, for his accomplishments in the sport.^[43]
