Gozo Shioda is a small man. He stands at 5'1 and weighs only 45kg. But that's not stopping him from being able to put larger men to the ground. The reason: he's a 10 dan Aikido master.

Shioda passed away in 1994, but at the height of his career, he was invited to a demonstration of his skills in front of US Attorney General Robert Kennedy. His bodyguards participated in the demonstration, trying to take him down.

They weren't close to a match for him. Check out the videos:
