Plato Colmillo

is a technique used by the Arrancar, Tesra Lindocruz.

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