“The Demolition Man” Alistair Overeem, 42, of Amsterdam, Netherlands has fought Badr “Bad Boy” Hari, 37, of Morocco three times. Two of the fights were won by the former.

The first fight was at “Dynamite!! 2008” on December 31, 2008 in Saitama, Japan when Overeem knocked out Hari via left Hook. The second fight was at the K-1 World Grand Prix 2009 semifinals on December 5, 2009 in Yokohama, Japan where Hari won via technical knockout via 2 knockdowns rule.

From December 30, 2011 to February 6, 2021, Overeem competed in the Ultimate Fighting Championship. He was supposed to challenge reigning Glory Heavyweight Champion Rico “King of Kickboxing” Verhoeven, 33, of Bergen op Zoom, Netherlands at “Glory: Collision 3” at the GelreDome in Arnhem, Netherlands on October 23, 2021.

However, Overeem withdrew due to an injury. He was replaced by Jamal Ben Saddik, 32, of Morocco, who lost via technical knockout via punches to Verhoeven.

On October 8, 2022, Overeem went back to the GelreDome where he and Hari headlined “Glory: Collision 4”. All of the nine bouts on the card ended via a decision.

After three three-minute rounds, Overeem’s hand was raised as the winner via unanimous decision. The judges scored his heavyweight bout against Hari 29-26, 28-27, 28-27, 28-27 and 28-27.

Right after the win, Overeem declared himself as the new Glory Heavyweight Champion so Verhoeven entered the ring and an exchange of words ensued. Verhoeven has yet to defend his title again after beating “Glory: Collision 3”.

Winning at “Glory: Collision 4” improved Overeem’s professional kickboxing record to 11 wins and 4 losses. Hari now has 106 wins, 17 losses and 2 No Contests while Verhoeven has 59 wins and 10 losses.
