Nikolai Valuev (Russian: Николай Валуев; born August 21, 1973) is the first Russian professional heavyweight boxing champion and the current holder of the WBA title. His alias used to be "The Beast from the East" but he now prefers to be styled "The Russian Giant."
Valuev is the tallest and heaviest recognized champion of all time, standing at 2.13 m (7''2") tall and weighing as much as 150 kg (330 lb). There are however other less successful boxers of similar stature in recorded history: George Mitu, Jim Cully and John Rankin were all 7''4" and Jimmy Black weighed in at 360 pounds prior to his match against Claude McBride on 1 June 1971
