Skill & Power: Belleza is overall an extremely powerful Arrancar. When he first became a hollow he was able to take on several lieutenant level Shinigami alone and succeed. He is also able to exert a considerable amount of Spiritual Energy without tiring, and his spiritual energy is also detrimental in a number of his attacks outside of standard sword fighting and hand to hand. His hand to hand skills are also something not to take lightly, as he has developed a technique that can kill an enemy instantly. He was recruited as the first 9th Ranked Espada, but his power levels are at minimum Ranked 7 or lower. Ulqiourra Cifer, a Rival of Belleza's as well, was barely able to match up to him when he sparred with him.
Fighting Style: Belleza fights with the utmost uninterest in fighting in general. He is very astute, however, and predicts attacks very easily. It usually depends on the rank of the enemy though, Captains have been able to elude him before. He tends to fight with extreme speed as he is faster than a majority of the Espada, and he is a lot faster than your average Vasto Lorde. He likes to fight without using his sword because killing is unnecessary unless you really need to kill your opponent, which usually, despite them being Shinigami, he doesn't need to. They'll go back and eventually somebody else will come after him. He is a relaxed fighter as well, even in strenuous situations and in the face of high magnitudes of danger he has shown his obvious monotonous attitude about battle. He doesn't take things too seriously which usually gives him an advantage because he doesn't have to worry about fighting with unease or uncertainty. However..... He has been known to lose his cool once or twice when people make fun of his appearance, given that he is somewhat feminine. This sometimes sends him into rage mode and he will begin to fight with immense speed and strength. He literally crushed Hollows with a flick of his finger at one point. This kind of power and speed is only displayed when he is in a bad mood already, and is tipped over the edge, or when he releases his Zanpakutou.
Reason For Position: Intelligence, and Strength. Belleza is an incredibly astute Arrancar with the intuitive and intelligence abilities of a modern-world genius. Not to mention his strength even equaled that of Ulqiourra CIfer, one of Grimmjow's old comrades. He is 9th only because he chooses to be a lower rank so he does not have to fight all the strong opponents unless specifically ordered to by Grimmjow. He prefers getting fights over with quickly, and enemies with abilities equal to or close enough to stand against Belleza for long periods of time were bothersome and uninteresting to him. Grimmjow was extensively filled in on Belleza's abilities as an arrancar, and sought him out himself to test his abilities.
Obtaining The Position: Eventually he was confronted by a certain Arrancar who claimed to be relaying a message from a "Grimmjow JeagerJaques", who apparently wanted to meet him and test his abilities. Belleza was adverse because he could already smell the the indoctrination in the air, but he decided there was no real reason to say no. The arrancar took him back to Hueco Mundo, where he was greeted by Grimmjow, claiming to want to test his mettle for a position in the newly formed Espada. Belleza anticipated this and just readied himself for it mentally. Grimmjow had been extensively filled in on Belleza's abilities and wanted to see them for himself his devotion and strength.
