Continuous Energy Bullets (連続気功弾 Renzoku Kikou Dan) are a combination of many energy waves fired at a very rapid rate, which causes a lightning speed effect. It is effective for quick, widespread, and massive amounts of damage, but it is very draining on one's own ki level. However, if they are powerful enough, they are able to avoid the ki drainage effects of this combination technique.
Many fighters in Dragon Ball Z and GT can perform this attack, but its most prominent user is Vegeta (in fact, during his fight with Majin Buu, Goku refers to it as Vegeta's technique). It was first used against Gohan, then Vegeta used the Continous Energy Bullets against Zarbon in his post transformation. Gohan used this against Frieza. Vegeta also used the Continous Energy Bullets against Frieza to form the Big Bang Storm. Piccolo used his version of the Continuous Energy Bullet, called Scatter Shot, against Frieza. Cui used this against Vegeta as a part of his Ah, Lord Frieza! technique. Goku used it against Cell who blocked it. Broly used his version of the Continuous Energy Bullet on Goku. Pikkon used it against Goku during the final of the Other World Tournament in the episode "Final Round". In Dragon Ball GT, Uub used the Continuous Energy Bullet against Baby, as well as did Pan with her Reliable Friend technique. Baby Vegeta used this and formed them as Continuous Super Galick Gun.
It is a running rag in the series for a victim of Continuous Energy Bullet's to reveal themselves out of the smoke left by the blasts and appear unphased, with the one who used the attack to look suprised.
Its various levels are named the Full Power Energy Blast Volley (used by GT Goku, Gohan, Goten, Guldo, and Baby Vegeta), Full Power Energy Barrage Wave (used by Super Saiyan 2 Gohan, Kid Trunks, Cui, Turles, Doore, Neiz and Salza) and Super Energy Wave Volley (used by Goku, Vegeta, King Vegeta, Majuub, and Tarble) in the Budokai Tenkaichi video game series, whereas it is called Full Power Consecutive Ki Blast in Dragon Ball Z: Infinite World and Energy Barrage in Dragon Ball Online. They are much more powerful than the average energy ki blasts. Like other techniques, this attack can be increased further through transformations, concentration, and training. Its power, speed, force, color, and size depends on the user. This technique is usually used as a last resort or a desperation move, typically motivated by frustration or rage. Great Apes and Golden Great Apes also have a Mouth Blast variation of this attack. Also in Dragon Ball: Raging Blast and Dragon Ball: Raging Blast 2, Vegeta uses a version of this attack that is called Galick Shoot.
