Mike Tyson Tyson's tattoos alone are enough to terrify anyone crazy enough to get in a ring with him. That he has spent time in jail, bit the ear of Evander Holyfield and was widely acknowledged to have one of the most ferocious boxing styles in the sports history only add to the fear factor. He's not nicknamed 'The Baddest Man on the Planet' for nothing.
Known as the 'Beast from the East', Valuev fights David Haye for the World Boxing Association heavyweight title in Nuremberg on 7 November.
One of the All Blacks greatest players was also one of the sports most intimidating. Standing at 6ft 5in, Lomu would dwarf his opponents and the ones that dared tackle him would be swatted away like flies. That he has since moved into the world of body building and can now be seen in skimpy underwear striking silly poses has somewhat tarnished his fearful reputation.
Manchester United's legendary goalkeeper Peter Schmeichel arguably terrified his team-mates more than his opponents. The Danish shot-stopper was regularly seen screaming at his back four, his face turning red and the spit flying as he let rip.
William Perry was nicknamed 'The Fridge'. His terrifying size had opponents on the football field fumbling the ball simply to avoid coming into contact with him. He also made a guest appearance on the A-Team, using his intimidating frame to calm down B. A. Baracus, who in truth, would have been a 'crazy fool' to cross him.
Never have the words "I'll get my brother on you" weighed so heavily. The Ukrainian boxers currently dominate their fields, knocking out anyone who stands in their way.
Known as 'Psycho', Stuart Pearce now busies himself terrifying England's under-21s. He earned his nickname during his playing days for his no-nonsense style on the pitch and his propensity to let his feelings be known with some venom. To relax in his spare time, Pearce is known to listen to punk music.
West Indies bowlers
The bowling quartet of Colin Croft, Malcolm Marshall, Joel Garner and Michael Holding (pictured) was the most feared in the game. Regularly using bouncers to terrify their opponents, when a batsman had the audacity to hang around at the crease, they had an ability to up the pace and bowl the ball with increasing venom until their opponent was sent packing to the pavilion. The fast-bowlers enjoyed various nicknames but Holding's 'Whispering Death' was probably the best.
England's World Cup winning captain was one of the greatest locks to ever play the game, but he was also one of the most terrifying opponents on the pitch. At 6ft 6in, 'Jonno' took great pleasure in crushing his opponents, and since his appointment as manager of the England team, he's shown no signs of curbing his intimidating nature.
For a genial sport such as golf to produce a player that can be described as terrifying is a nod to Daly's unique character. Although not particularly successful on the tour, Daly has garnered a fierce reputation for his antics off the course and unpredictable nature on it. Lawsuits, divorce, drugs and alcoholism have all played a part in the life of the golfer who once smashed a spectator's camera against a tree for daring to get too close.
Seven-time Formula One world champion Michael Schumacher is rightfully regarded as one of the greatest drivers of all time. Yet his driving style did have something of the kamikaze about it. Fellow drivers knew that if you didn't move out the way, Schumacher would happily drive straight into you, and never so willingly as when the driver's title was on the line. In 1994, Schumacher collided with Damon Hill, an incident that meant both drivers were forced to retire, handing Schumacher the title by one point. Then in 1997, the German collided with Jacques Villeneuve in the final race of the season. The crash ruled Schumacher out, but this time his opponent was able to complete the race and Villeneuve walked away with the title.
Size wise, the Irishman is not the most intimidating of characters, but never has a stare been used to such great effect. Manchester United's midfield general even admitted deliberately injuring fellow professional Alf Inge Haaland in a 'revenge' attack and since moving into management has garnered a reputation as the most feared man in football
The French international looks like an extra from 'Braveheart'. His full beard and long hair, coupled with his ferocious tackling style have led French rugby fans to nickname him 'Homme des Cavernes' - the Caveman.
British boxer David Haye is currently preparing himself to fight Nikolay Valuev - the seven foot tall, 23 stone giant from Russia.
If his physical appearance is not enough to strike fear into his opponent, the story that Valuev once killed a wild boar with his bare hands should be enough to have Haye cowering in a corning.
Here we salute the most terrifying sportsmen.
