Ki Blasts (気砲, Kihō; lit. "Spirit Blast") are formed and discharged portions
of ki, which are frequently used in theDragon Ball franchise for fighting. Depending on their usage and power of the user, these discharges can be destructive and can even cause cataclysmic damage depending on the ability and power of the person using them, ranging from mountains, cities, continents, planets, solar systems to galaxies. The most frequently referenced Ki Blast in the series is the Kamehameha, as it is Goku's favorite finishing move.
Its power is usually determined by the amount of energy put into it, or the person using it. Ki Blasts have some sort of substance or mass, because it is possible to deflect ki blasts by slapping them away.
This technique has made appearances in almost every video game spun off by the series, particularly in the Butōden series, Dragon Ball Z: Legendary Super Warriors, the Legacy of Goku series, the Supersonic Warriors series, the Budokai series, and Budokai Tenkaichi series, where it is the most basic and common form of energy wave.
