Super 17 moves sideways very close to his opponent as he charges a purple and black energy sphere on his hand. Then, he fires a small yellow energy wave out of the energy sphere at the opponent at point blank, inflicting a great amount of damage.

This technique was named in Dragon Ball Z: Infinite World, where it is one of Super 17's super attacks. In the Budokai Tenkaichi series, Super 17 uses regular Rush Ki Waves and Full Power Energy Waves.

— Dragon Ball Xenoverse in-game description
In Dragon Ball Xenoverse, Thunder Eraser appears as one of Super 17's Super Skills and the finishing blast has the added effect of blinding opponents. It also appears as one of Mira's Super Skills in his 3rd skillset in the GT Pack 2 DLC. It can also be obtained by the Future Warrior by making a wish to Shenron for more Super Skills.
In Dragon Ball Xenoverse 2, Thunder Eraser returns as a Super Skill which can be obtained by the Future Warrior by purchasing it from the Skill Shop after defeating Kid Buu in the main story. It functions the same way it did in Xenoverse.
