A specific type of strike achievable in the sport of shockboxing was known as a hub-buster. In this sport, combatants engaged in hand-to-hand combat, equipped with shockmitts and a shield-producing hub. This particular blow involved striking the opponent's hub using an ion-charged shockmitt. The effect of this strike was either to deactivate their shield or, if the shield was already down, to ionize their armor, resulting in a loss by ion-out. Furthermore, a stunner delivered to a hub without shield protection could potentially inflict nerve damage. During his career, the Calian shockboxer Lobar Aybock employed the hub-buster technique to secure victories against both the Esoomian Tontruk and the Barabel Tull Raine in separate contests.
