High-Pressure Energy Wave (高圧縮エネルギー波) is an energy wave used by Android 18. She puts her hand forward and charges a yellow energy sphere. Then, she fires the sphere in the form of an energy wave at the opponent, inflicting a great deal of damage.
Future Android 18 uses this attack a few times throughout her various battles. She first uses a two-handed version to kill Future Tien Shinhan, and then a one-handed version to severely injure Future Yajirobe. (only to escape after being fed by a Senzu Bean by Future Korin, according to him).
Later, Future Android 18 uses the High-Pressure Energy Wave to kill a Super World employee, and soon after to blast Future Trunks away from Future Gohan during the latter's battle with Future Android 17. She uses it again to defeat Future Trunks in their second battle, though the young Saiyan manages to survive it; when Future 18 charges the attack, she raises her hands above her head.
Android 18 uses it to destroy a forest while riding a Lucky Food's truck with Android 17 and Android 16 on the way to Goku's house. She later uses the High-Pressure Energy Wave to destroy the screen in Lord Jaguar's Battle Arena in his castle.
