Wilt Chamberlain: He was 7'1'' (2,16 m), was in the Hall of Fame of volleyball and basketball, dropped 100 points in a game, did a 20-20-20 game, allegedly (take this one with a pinch of salt) had a 47 inch vertical (119 cm), 6'6 high jump personal best (2 meters), 24 foot long jump (7 meters, from the 3-point line to the rim), 9 and a half foot standing reach, allegedly blocked 23 shots in a game, was a member of the Harlem Globetrotters, was friends with Arnold Schwarznegger, etc.
Grigory Rasputin: Besides from being a mystic, saving the life of the czar's son and some other things, the guy was pretty hard to kill. An assassin was sent by a monk to kill rasputin by stabbing him, he survived. People connected with Tsar Nicholas tried to poison him with cyanide, he survived. Some day, the attempt is successful. He took 3 bullets, one next to the forehead. He probably was a religious charlatan, but he was tough.
Simón Bolívar: Simón was a revolutionary that was very important in South America. he helped in the independence process of Bolivia, Colombia, Ecuador, Peru and Venezuela. Ok, the guy was a dictator for a short part of his history, but still, if no one had his influence, probably South America would look like Oceania, with a bunch of UK overseas territories.
