Didier Ilunga Mbenga, also referred as D.J. or The Thing Assassin (born December 30, 1980), is a 7'0" Belgian NBA center who plays for the Dallas Mavericks. He comes from Congo and was signed to a two year contract by the Mavericks in the 2004 offseason.

Didier Mbenga lived in Congo for seventeen years as the son of a family involved in the Congolese government. When his father's term was over, the new regime hunted down everyone who worked for the previous leaders. His father died in unknown circumstances and it is unclear if the new regime were the ones behind it. During the war between the Tutsis and the Hutus Didier was falsely accused of being Tutsi and was put in a prison with execution waiting on him in the long run. In the year 1999, after a whole nine months being heavily mistreated in prison, Didier managed to escape after his brother bribed one of the prison guards. Fearing for their lives, Didier and his mother got on a flight out of Congo as soon as possible. The first available flight lead him to Belgium where they were given political asylum. Later on, he would also pick up the Belgian nationality.

Once in Belgium, Didier stayed at an asylum center in the town of Kapellen, where he was spotted on the streets by former Belgian basketball legend Willy Steveniers. Impressed by his physical appearance, he offered to teach Didier the game of basketball. In the time to come, Steveniers would serve as Didier's personal basketball mentor as well as substitute father.

The duo's dream of Didier once playing in the NBA became reality in 2004, when he joined the Dallas Mavericks after spending a few years in various Belgian basketball leagues.

Didier Ilunga Mbenga had not even see a basketball until the age of 19. He is seldom used in games by the Mavericks' coaching staff. Although he's shown spurts of defensive talent in very limited playing time, mostly at the end of games which already have been decided, the African native hasn't show much on the offensive end. However, he retains a devoted following of fans in Dallas. So much, in fact, that the Mavericks have recently started selling his jersey shirts, which have sold with surprising success.

When the 2005-06 season concludes, Didier became an unrestricted free agent. Didier Mbenga extended his contract with the Dallas Mavericks for three seasons for an approximated $2 million USD a year.

Didier Mbenga is a solidly built big man that runs the floor extremely well. Due to his inexperience and lack of basketball experience, he aggressively goes for blocks that often lead to fouls or open shots for the man he is supposed to be guarding. His offensive game at the moment is very limited to non-existent. Nonetheless, he remains a coach's favorite, for his willingness to compete and the heart he puts into the game of basketball. On February 13, 2006, Mbenga had a career high 5 blocks in 15 minutes against the New York Knicks.

In the 2006 playoffs he was suspended 6 games without pay for entering the stands. He saw coach Avery Johnson's wife being disturbed by some fans, and reportedly went into the stands with owner Mark Cuban to help usher Mrs. Johnson to the locker room. Regardless of his intentions, the NBA's Stu Jackson maintained a hard line against players entering the stands (a direct result of the infamous Pacers-Pistons brawl of 2004-2005), suspending him for six games without pay.

Mbenga speaks many different languages including two languages from the Congo, French, Portuguese, and limited English
