Asguiaro Ebern (アズギアロ・イーバーン, Azugiaro Ībān) is an Arrancar in the service of the Vandenreich often called Ebern the Honorless (アズギアロ イーバーン, Ebern no Eiyonon) for being one of the first of his species to willingly side with Hueco Mundo's invaders. For his actions, Ebern was given a high rank among the Vandenreich but is looked upon unfavorably by his fellow Arrancar. Unknown to the rest of his species, Ebern was the sole reason for their continued existence as the Vandenreich planned for a purge of Hueco Mundo. Thanks to Ebern's convincing, any and all Arrancar were given a chance to serve the Vandenreich in exchange for their lives in what Ebern believes to be a 'fair trade'.
