Rugir der Dragon (龍哮拳 (リュヒル・デル・ドラゴン), ryuhiru deru doragon; Spanish for "Roar of the Dragon", Japanese for "Dragon Roar Fist") is a technique used by Gantenbainne Mosqueda in his Resurrección, Dragra.
Escalating his capability to collect and condense reishi to its greatest degree, Gantenbainne generates a compact sphere in front of each of his fists, before uniting these into an enormous singular orb. Drawing back his right arm, the accumulated energy adopts the form of a dragon's head, which he then proceeds to propel forward with a potent punch in order to attack an opponent.
As a testament to this projectile's strength, despite being intercepted by Yasutora Sado's Brazo Izquierda del Diablo, the dissipated energy still possessed enough power to damage the surfaces it came into contact with.
