The Hyper Explosive Demon Wave (超爆裂魔波) is Piccolo's trump card in his fight against Goku near the end of the 23rd World Martial Arts Tournament. This technique is named Full Power Shōgekiha (フルパワー衝撃波; lit. "Full Power Shock Wave") in Daizenshuu 2.
Piccolo creates a massive explosion with himself as the nexus. While having a very large radius, the attack was not very effective: it did little damage to Goku (who had time to block) and left Piccolo almost completely drained. In the movie Dragon Ball Z: The Return of Cooler, Piccolo uses this attack to destroy a large number of Cyclopian Guards, creating an enormous crater on New Namek.
In Dragon Ball: Plan to Eradicate the Saiyans, a weaker version is used by Piccolo to send Bude and several other of Dr. Lychee's henchmen flying. Piccolo uses this weaker version both in West City and the Land of Ice.
Vegeta uses a very similar attack in the late stages of his first battle with Goku, but it did not do much as Vegeta's power was weakened due to his being hit with the Spirit Bomb. This technique is called Super Explosive Wave in the Budokai Tenkaichi series. The Namekians Nail, Lord Slug and the alternate Future Gohan also use the Super Explosive Wave technique in the Budokai Tenkaichi series.
Recoome has a similar technique called Recoome Ultra Fighting Bomber, which he describes as his ultimate technique. It causes a "whole big wide circle" around him to be blown into nothing when used. Majin Buu also uses a similar technique, during his battle with Majin Vegeta, called Angry Explosion.
In See The Wall That Must Be Passed! Goku vs Gohan, Piccolo and Gohan battle against Tien and Goku. With Gohan and Piccolo's devised combinations attacks, Piccolo powers up this attack once again, while Gohan fights off Tien and Goku so Piccolo can gather enough energy to use it. When Piccolo unleashed this attack finally, Goku is able to hold it off and deflect it, preventing it from damaging both him and Tien.
Appearances in games
This technique appears under the names Earth Destructing Wave (地球破滅波) in Dragon Ball 3: Gokuden, Dimensional Barrier (魔神結界) in Super Dragon Ball Z, and Super Explosive Wave in Dragon Ball Z: Attack of the Saiyans.
"Send your enemy into a flying tailspin by triggering a powerful explosion."
— Dragon Ball Xenoverse Skill description
In Dragon Ball Xenoverse, it appears as one of Piccolo's Evasive Skills under the name Super Explosive Wave. Piccolo also teaches it to the Future Warrior while they are training under him. In the Xenoverse series it is depicted as Evasive Skill where the user unleashes strong explosive wave that damages and sends nearby opponents flying making it useful for situations where the user is surrounded. As it is an Evasive Skill it requires 3 stamina bars to perform. As a result, it is depicted as being more defensive in the Xenoverse series and resembles Piccolo's usage of the technique in Dragon Ball: Plan to Eradicate the Saiyans.
"Creates a Ki explosion, sending nearby foes flying."

- The name of the technique is based on another one of Piccolo's strongest attacks, the Explosive Demon Wave.
- In the first dub version of the Frieza Saga, Piccolo has a flashback about when he used this move. However, it is mistranslated as him crying out in pain from Goku's "unbelievable power" rather than him being the source of it.
- The names Explosive Wave and Super Explosive Wave can be used as a generic name for various nameless "Hyper Explosive Demon Wave"-like techniques used by various characters throughout the series. Piccolo's technique is even called Super Explosive Wave in the RPG Dragon Ball Z: Attack of the Saiyans.
