To use this technique, two or more fighters must fire and combine their waves of energy, increasing the power of the beam.
The combined attacks are used in the movie Dragon Ball Z: Dead Zone, where Nicky, Ginger and Sansho fires their beams at Piccolo hitting him and knocking him out, and later at Goku, who was saved by a Ki Blast from Krillin. The beams fuse together to make a giant white energy wave. Goku and Piccolo later fire a point blank Combined Energy Wave at the transformed Garlic Jr., but it has no effect on the powerful Makyan.
In the Vegeta Saga, Krillin and Piccolo perform a team attack against Nappa during their battle at Paprika Wasteland, which they finish with Krillin firing a Kamehameha and Piccolo firing a Makosen. The attack is ineffective on the powerful Saiyan, though. During the Namek Saga, the Namekians in Tsuno's village fire this attack at Vegeta, but Vegeta emerges from the rocks under which he was sent by the attack and throws them at the Namekians who attacked him using an Explosive Wave.
In Dragon Ball Z: The Tree of Might, the space pirates Daiz and Cacao fire a Combined Energy Wave at Goku, creating an enormous explosion. Goku blocks it with an Energy Shield though. In Dragon Ball Z: Lord Slug, Lord Slug's soldiers fire several energy waves to attack and kill many civilians. They later use this technique against Gohan, but he dodges all the blasts.
The Ghost Warrior versions of Frieza and Turles use this attack against the Z Fighters. Later, the Z Fighters use a combined energy wave to defeat Hatchiyack during their battle on the Dark Planet.
In Dragon Ball GT, Sheela and Gale use this attack on Goku, Trunks, and Pan in an attempt to stop them from invading Don Kee's fortress Goku, but Goku counters the wave with a Kamehameha. Later, Goku and Pan use the technique to destroy Luud. When the past villains escape from Hell in the Super 17 Saga, Goten and Trunks combine their energy waves to destroy Android 19 in a manner similar to the Androids' Non-stop Violence technique. While Frieza and Cell fight Goku in Hell in the same arc, the two villains use a combined energy wave in an attempt to kill the Saiyan.

In Dragon Ball Heroes, using Card Action Ability: Z allows the Z Fighters to combine their power in a Combined Energy Wave. To use this, the player has to draw a "Z" on the game board with the card. After dealing damage to the opponent, extra beneficial effects such as energy recovery can be shared among the members of the team.
In Dragon Ball Xenoverse 2, during the climax of Future Trunks and the Future Warrior's battle with Dark Turles and Dark Lord Slug, Slug combines his Darkness Blaster with Turles' Sudden Storm-like Energy Wave in a final attack to destroy the two Time Patrollers, however Trunks counters with a Burning Attack energy wave combines with an unnamed energy wave used by the Future Warrior, overpowering Turles and Slug's combined energy wave, defeating the pair.
