<p>The original Japanese term is ki (pronounced the same as "key", written as 気). It can also be spelled chi or qi. The same term is used for a concept in martial arts.</p>

<p>In One Piece series, there's this 'will' technique called Haki. Is this based on anything real, all three of them?</p>

I wouldn't say Haki is real but i think its the closest to severe and thorough Martial arts body condition training. We have seen people punch through several bricks, or Muay Thai fighters break an entire opponent's arm and part of the ribcage by just a kick... its body conditioning through vigorous training for years.

Anime is far from reality, imagine the disaster if such cases is for real. Perhaps, we human being only have natural instinct, and that is the reality.
