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.
In Dragon Ball Z: The History of Trunks, 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.
In the "Extra Edition 1" bonus chapter of the Dragon Ball Super manga, Future Android 18 uses the technique against the Future Dragon Team.
