Plato Colmillo

is a technique used by the Arrancar, Tesra Lindocruz.

Description
While the circular portion of his Zanpakutō is typically hollow, Tesra can choose to solidify the interior of this ring at will by materializing a barrier of thick Reiatsu, creating a small shield that can be used to block incoming attacks. Despite its fragile appearance, the resulting shield is remarkably tough, being able to completely nullify even a desperation attack made by Yasutora Sado using his Brazo Izquierda del Diablo.
