Dragon Ball AF Fanon Wiki

Super Explosive Wave is one of the Blast moves in the Budokai Tenkaichi video games series. The user takes their time for a few seconds, then they explode with a gigantic energy wave that, if the foe contacts with the blast, will deal much greater damage than the normal Blast 1 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.
