The user stands charging energy around their body, then they explode with a gigantic energy sphere around their body. If the foe comes in contact with the Super Explosive Wave, it will deal much greater damage than the normal Explosive Wave. It can also be used for defense and offense at the very same time. It also appeared in the anime and some other video games with similar effects. The larger the user or the more ki they have, the wider and more enhanced it will become.
Video Game Appearances
The Super Explosive Wave is one of the Super Attacks in the Budokai Tenkaichi series and Dragon Ball Z: Battle of Z (used by Super Saiyan Teen Gohan and Super Trunks only in the latter). It is a very powerful generic super move, usually a Blast 2 technique or an Ultimate Blast for some characters, that creates a large, temporary danger-zone of ki energy around the (stationary) user and causes high barrage type-damage if the opponent is too (or gets too) close to said user. It is also capable of blocking Blast 2 attacks and Ultimate Blast versions can block other Ultimate Blasts.
The Big Bang Kamehameha is the only Blast 2 attack that can travel through a Super Explosive Wave and harm the person using it in Dragon Ball Z: Budokai Tenkaichi 3 and Dragon Ball Z: Tenkaichi Tag Team. In fact, Gogeta's Big Bang Kamehameha, Gohan's Father-Son Kamehameha and Bros. Kamehameha, Vegito's Final Kamehameha, and Cell's Solar Kamehameha are the only attacks that are strong enough to pass through Super Explosive Waves.
In the Xenoverse series, the Hyper Explosive Demon Wave appears under the name Super Explosive Wave where it functions as an Evasive Skill used by Piccolo. Both Future Warriors are taught the skill by Piccolo while training under him. In Xenoverse 2, it also appears as Nail's Evasive skill. Unlike past depictions it is somewhat weaker and functions as an Explosive Wave that sends nearby opponents flying (though is still more powerful than the Explosive Wave evasive skill which only causes opponents to stagger).
