A Martial Artist (武道家, butōka) is a person who practices martial arts. Martial arts are a recurring discipline practiced in the Dragon Ball series. The purpose of martial arts training is to push one's physical condition so that they become stronger. The main characteristic of Martial Artists is their ability to use Ki.

Ki is also known as "latent energy" or "fighting power." This force is a tangible energy inside every living being, with its major focus being in the center of the body. By drawing it out, an individual is able to manipulate it and use it outside the body. Ki can be used for many different techniques. Because there are physical limits to the strength of the body itself, it is necessary to increase one's ki to overcome this barrier and become stronger. Usually, the more concentrated the masses are, the more time the user requires to draw it out by powering up. When fighters gather ki, they are able to gain enhanced strength, speed, endurance, and can increase the power of their attacks to inflict greater damage to opponents. Normally, the more the ki is increased, the harder it is to control, so ki control is also important. The main usages of ki include forming Auras that radiate from the user when increasing the concentration of it inside their body, manipulating ki energy to allow the user to fly, sensing the location and life force of anyone from afar, and firing Ki Blasts, which are formed and discharged portions of ki that can be destructive and can even cause cataclysmic damage depending on the ability and power of the person using them.
