Riñaquim Eldrosa

Riñaquim Eldrosa is the Decima (Tenth) Espada in the Espada led by Kamui. He originally appears as a weak Espada, only a fraction above the Arrancar that serve him, but later reveals that his ability is not what it seems.

Personality
Riñaquim is usually seen as a very calm and somewhat serious individual. He rarely shows any surprise and commonly has a slightly amused look to him, as well as confident. He is ominous, foreboding, and shows immense confidence that he will win all battles. During some battles he shows a more excitable side, which has led to his fame, as he becomes maniacal and possessed. He is also cruel and pitiless, believing that everyone but a piece in a game, or a toy placed there to amuse him before he breaks it. Riñaquim seems to think that his enemies are not worthy of his attention and rely on heathen techniques.

Riñaquim follows Kamui because he feels warmth and loyalty towards Kamui to the extent where it is a religion to him, and worships Kamui as others do God. He becomes enraged when others insult or threaten his master, and has, at least on one occasion, showed more wrath at the interruption of Kamui's plans than to his own beating to near death. When enraged in such a way, he goes even beyond his normal state of battle lust, often resulting in gruesome massacres.

Background
Before becoming a member of the Espada, Riñaquim was a hollow. Kamui came across him not long before obtaining the Hogyoku. Having studied its powers, the Kawahiru attempted to create a natural Arrancar out of Riñaquim, one to match the artificially made ones produced by the Hogyoku. While he was able to create a full and complete Arrancar, no longer an imperfect one, Riñaquim did not achieve the full level of power that he could have from the Hogyoku, making Kamui realize that an attack on Soul Society was needed. Riñaquim, however, still possessed not insignificant strength, and so became an Espada.

Abilities
Hierro: (鋼皮（イエロ）, Hiero; Spanish for "iron") refers to the hardened skin of the Arrancar, which is a result of their compressed spiritual power. While their skin is strong enough to block even released Zanpakutō bare-handed, it is by no means impenetrable. Stronger Arrancar have proportionally stronger skin. Riñaquim's hierro, while not originally very strong, is strengthened by one of his abilities.


 * Hachimai: (ハチ舞, Hachimai, Japanese for Bee Dance) is a technique, demonstrated only by Riñaquim, combines Sonido with Hierro, vibrating tiny increments at such speed that the force of movement concentrates tha ability to one area of the skin, but the point of most pressure is shifting so rapidly that the entire skin gains this benefit, increasing the Hierro's ability greatly.

Sonido:Riñaquim is able to vibrate his body at speeds higher than the fastest Sonido, meaning that his speed in small increments is unmatched. In movement across distances, he still possesses great speed, seeming to move to everywhere between his departure and destination simultaneously, due to his erratic way of moving by vibration.

Gran Rey Cero: As an Espada, he is able to use this Espada-exclusive Cero variant, which produces a larger and more powerful version of the normal Cero, enough potentially to cause great damage to Las Noches itself. In order to fire it seems Riñaquim must first cut his own hand on his Zanpakutō. Riñaquim's Gran Ray Cero is colored dark blue.

Cero: Riñaquim has been shown using Cero in a very strange manner, firing it from the tip of his hairdo with extreme effects. His Cero is a murky dark gray and, oddly, possesses a yellow core, instead of red all throughout, which is more common among Arrancar and Hollows.

Bala: The technique hardens the user's spiritual pressure and fires it like a bullet from their fist. Riñaquim has the generic red Bala.

Swordsmanship Specialist: Riñaquim has demonstrated terrific ability in the usage of a sword, wielding multiple short swords by tossing them in the air and dancing around his opponent to catch them. This strange style has proven effective against opponents who would otherwise be the undisputed victor in a conventional swordfight.

Resurrección
When sealed, Riñaquim's Zanpakutou takes the form of an unconventional dagger with a short, rapier-like blade, styled to resemble a bee's stinger, which is the result of two bony horns on the top of a skull, which serves as the guard, combining. It has never been seen except in a flashback, so it is unknown where he stores it.
