Lightning King Quake is an anti-ground long-range technique which erupts lightning from below the enemy, traveling through any material in order to reach its target. It is performed by Ox Ford and Harvar D. Éclair.
When performing the attack; Ox begins by rapidly spinning Harvar, in his weapon form, above his head while raising one of his legs. He then simultaneously brings down both Harvar and his leg, conducting the generated electricity through the ground directly below, towards its intended target.
- Ox's actual initial demonstration of this technique occurred during Chapter 34 but it remained unnamed until it appeared again in Chapter 46. The ability itself is conducted in the same manner, with Ox performing a spin with Harvar before using the impact of his foot to conduct the electricity, but instead the resulting shockwave is manipulated to disperse a large number of opponents.
