Kohei Uchimura is no fan of "noisy arenas," so the Japanese superhero should invest in some heavy-duty earplugs when he heads to Rio next August bidding to become the first gymnast in more than 40 years to win back-to-back Olympic all-around titles.

The all-conquering gymnast, who has been immortalized in comic strips in his homeland and has many screaming teenybopper fans around the world, will arrive in Brazil as the holder of a record six world all-around titles.

After collecting every Olympic and world all-around title since taking silver at the 2008 Beijing Games, 'King Kohei' will be favorite to become the first man since compatriot Sawao Kato in 1972 to win successive Olympic all-around titles.
