Wladimir Klitschko is a Ukrainian heavyweight professional boxer. Klitschko is the WBA (Super), IBF, WBO, IBO & The Ring Heavyweight Champion. His older brother Vitali Klitschko is the current WBC Heavyweight Champion. Klitschko is the longest reigning IBF, WBO & IBO Heavyweight Champion in history with the most title defenses for those organizations.

Overall, he is the 5th longest reigning Heavyweight Champion of all time with the 3rd most consecutive title defenses at 13. As of December 2012, Boxrec rates Klitschko as the number 3 pound-for-pound in the world. Ring Magazine currently rates Klitschko as the number seven pound-for-pound boxer in the world. Klitschko turned professional with Universum Box-Promotion in Hamburg under the tutelage of Fritz Sdunek. He suffered his first setback after 24 bouts without a loss to journeyman Ross Puritty, who entered the bout with a record of 24–13–1. Wladimir Klitschko's coach, Fritz Sdunek, jumped into the ring and stopped the fight. On 18 March 2000, Wladimir fought Paea Wolfgramm, whom he fought previously in the 1996 Super Heavyweight Olympic Finals. In their professional rematch, Klitschko knocked Wolfgramm out in the first round. Klitschko defeated WBO Heavyweight Champion Sultan Ibragimov at Madison Square Garden in New York City on 23 February 2008 to unify the IBF, IBO & WBO Heavyweight titles. The Klitschko-Ibragimov fight was the first heavyweight unification since Holyfield-Lewis in 1999. The unification clash with Ibragimov proved to be a huge disappointment for fans. Klitschko was very dominant from the first bell. He backed Ibragimov into a corner and proceeded to push down Ibragimov's glove with his left hand so he could not throw a punch. Though Klitschko won every single round the crowd in New York began booing after the second round. The boos and jeers increased as the fight progressed in the same fashion. Ibragimov's corner was almost silent from the sixth round onwards unable to give their man any meaningful advice.

On 12 July 2008, at the Color Line Arena in Hamburg, Klitschko defeated Tony Thompson by eleventh round knockout. Klitschko was scheduled to defend his titles against Alexander Povetkin later in 2008, but on 25 October, Povetkin withdrew from the fight due to an ankle injury. Instead, Klitschko faced Hasim Rahman on 13 December 2008 and won by TKO. This was the third time Klitschko fought at the SAP Arena in Mannheim, Germany. He dominated the fight, winning every round while making good use of his left jab. From the first bell the difference in physical strength was profound. Rahman seemed unable to withstand Klitschko's punch power. The referee finally called a stop to the one-sided contest in the 7th round after Rahman failed to respond to a series of good shots.
