Rugir del Dragón

is a technique used by Gantenbainne Mosqueda while in his Resurrección, Dragra.

Description
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. As Gantenbainne draws back his right arm, the accumulated energy adopts the form of a dragon's head, which Gantenbainne propels toward an opponent by punching it. 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 which it came into contact with.

Trivia

 * In the third Bleach databook, this technique's name is improperly romanized as Rugir der Dragon.
