Shaun White
United States
American Shaun White holds the all-time X Games record with 15 gold medals, earned primarily in snowboard halfpipe and superpipe events. Nicknamed "The Flying Tomato," White also won three Olympic snowboard halfpipe golds (2006, 2010, 2018). He continually pushed the sport's technical frontier, debuting tricks like the Triple Cork 1440 -- considered impossible at the time -- in competition.
