Klitschko is known for his powerful punches and exceptional chin. With a 88.89% knockout percentage rate, he holds the best knockout-to-fight ratio of any champion in heavyweight boxing history. He has never been knocked down in any professional boxing bout, and has also never lost a decision. His two losses have come via a shoulder injury during a fight and a deep cut above his eye, which did however result in TKO losses. His power and his possession of a Ph.D has led to his nickname, Dr. Ironfist.
Klitschko's younger brother, Wladimir Klitschko, is the WBA (Super), IBF, WBO, IBO and Ring Magazine world Heavyweight Champion. He was awarded Germany's highest civilian award, the Federal Cross of Merit, for his varied accomplishments. On December 2011, Ring Magazine rated Klitschko as the number ten pound-for-pound boxer in the world.
Klitschko won the super heavyweight championship at the first World Military Games in Italy in 1995. Vitali won the silver medal at the 1995 World Amateur Boxing Championships in Berlin, Germany, where he was defeated by Russia's Alexei Lezin in the final. In his autobiography, published in Germany in 2004, the boxer revealed that he tested positive for a banned steroid in 1996. He attributed the presence of the drug to treatment of a leg injury but was dismissed from the Ukrainian boxing team and missed the Atlanta Olympics. His brother Wladimir moved up from heavyweight to super-heavyweight to take his place in the squad. His amateur record was 195–15 with 80 knockouts.
Klitschko began his professional boxing career in 1996, winning his first twenty-four fights by either early knockout or technical knockout (TKO). He and Wladimir signed with the German athlete-promotion company Universum. With both brothers holding Ph.D.s and being multilingual, their refined and articulate personalities made for mainstream marketability when they moved to Germany and Universum. In time, they became national celebrities in their adopted home country. In his 25th pro fight, on 26 June 1999, Klitschko won the WBO heavyweight title from Herbie Hide of the United Kingdom by a 2nd round knockout.
He successfully defended the title twice. He defeated Ed Mahone by knockout in the third round, and beat Obed Sullivan who retired after the ninth round.
Klitschko began campaigning for mayor of Kiev shortly after his retirement in 2005. He lost the 2006 mayoral election to Leonid Chernovetskyi but placed second with 26% of the vote, ahead of the incumbent Oleksandr Omelchenko. Klitschko campaigned on an anti-corruption platform and lead the bloc "Civic party" PORA-ROP (the parties PORA and Reforms and Order Party) in the simultaneously held local elections for the Kiev City Council. Analysts stated his relatively late entry into the campaign might have cost him votes. Still, Klitschko was elected as a people's deputy to the Kiev City Council since "Civic party" PORA-ROP won 14 seats in the 2006 election.
In the May 2008 Kiev local election he ran again and won 18% of the vote. Klitschko simultaneously led the Vitaliy Klychko Bloc that won 10.61% of the votes and 15 seats and again he was elected into the Kiev City Council. His campaign hired Rudy Giuliani as a consultant for the campaign. In 2008 he was also appointed to the Ukrainian delegation of the Congress of the Council of Europe.
Klitschko became the leader of the political party UDAR of Vitaliy Klychko in April 2010. During the 2010 Ukrainian local elections the party won representatives in (Ukrainian) municipalities and Oblast Councils (regional parliaments).
In October 2011 Klitschko announced that he would compete in the 2012 Kiev mayoral election.
