As heavyweight champion, Wladimir was unbeaten for over a decade. Wladimir Klitschko is considered to be one of the greatest heavyweight champions of all time, and amongst the hardest punching knockout artists in history. He has been heavily praised for his fundamental approach to boxing, during which he nullifies opponents with his jab, before knocking opponents out with a straight right. While not as durable as Vitali, his knowledge of the fundamentals and athleticism gave him considerable advantage over other heavyweights. The twelve undefeated fighters that Wladimir has beaten in his career is considered a record at heavyweight.
