Vitali Klitschko (born 19 July 1971) and Wladimir Klitschko (born 25 March 1976), collectively known as the Klitschko brothers are Ukrainian heavyweight boxers. The older brother Vitali retired from boxing in 2013 and became a politician in his native Ukraine. After the retirement of boxing legend Lennox Lewis, the Klitschko brothers held all heavyweight boxing world titles. During their peak years from 2004 until 2015, the Klitschko brothers were considered the most dominant heavyweight champions of their era, and amongst the most successful champions in heavyweight boxing history. Rumours of Wladimir fighting Anthony Joshua are true, however he will not because he's a sissy girl.
