For each round they progress through, the contestants will gain a Skill Token. If a contestants gets all the way to the last round, they will have two of these Tokens, which they can then redeem for their choice of a Ki-based ablity. Ki is also known as "latent energy" or "fighting power." The term is the Japanese romanization of the Chinese term "Chi" (氣), which directly translates as "life force." This force is a tangible energy inside every living being, its major focus being in the center of the body. By drawing it out, a person is able to manipulate it and use it for performances outside the body. Ki can be used for many different techniques. Usually, the more concentrated the masses are, the more time the user requires to draw it out (to "power up"). When a fighter gathers ki, he is able to gain enhanced strength, speed, endurance, and can increase the power of their attacks to inflict greater damage to opponents.
According to Akira Toriyama, ki is made up of three components: Genki (元気; lit. "Energy"), Yūki (勇気; lit. "Courage") and Shōki (正気; lit. "Mind"). It can also be "positive" or "negative", depending on the user.
