Yammy Llargo

is an Arrancar in Sōsuke Aizen's army, in which he holds the rank of décima (10th) Espada.

Appearance
Yammy is a giant, dark-skinned Arrancar with an odd, ridge-lined cranium bearing a resemblance to the example Adjuchas-class Menos. He has long, bushy sideburns and a thin ponytail, but aside from that, he is bald. He also has red markings under his eyes. Like all Arrancar, he has a large hole signifying his previous time as a Hollow in his chest. What remains of his Hollow mask is the jawbone (complete with teeth), which rests on his chin. A tattoo of the number 10, signifying Yammy's rank and level of power amongst the Espada, is on his left shoulder.

Personality
Yammy is portrayed as arrogant and confident in his abilities. He is also quite brutal, shown when a female Arrancar medic reattaches his severed arm. To test the new arm's strength, he punches the medic's head and destroys it, instantly killing her, and only grumbles that his original arm should have split her in two. (Note: in the anime, due to censorship reasons this action is changed to slamming her into a wall and grumbling that he should have been able to punch her through it.) He relies on Ulquiorra to explain things and give him orders while in battle, but is shown to function well without him during a subsequent Karakura raid.

Arrancar arc
Yammy first appears in Karakura Town along with his superior, Ulquiorra Schiffer, as the first team of Arrancar to scout out the human world. Their mission is to collect information on Ichigo Kurosaki. Shortly after arriving, several ordinary humans gathered to gawk at the crater that Yammy and Ulquiorra had made with their arrival. Yammy assumes the humans are staring at him, ignorant of the fact that most humans are incapable of seeing spirits, and proceeds to suck out the souls of every nearby human out of frustration. Only Tatsuki Arisawa survives the encounter. Yasutora Sado and Orihime Inoue arrive and attempt to fend off Yammy, but he easily defeats Sado, and is not even remotely harmed by Orihime's Koten Zanshun, grabbing Tsubaki and crushing him to pieces with his bare hands.

When Ichigo arrives at the scene, he quickly uses his bankai and slices off Yammy's arm, in revenge for injuring Sado. Yammy appears to be losing until Ichigo has to battle his inner hollow for control of his body. Yammy takes the opportunity to gain the upper hand, repeatedly punching Ichigo. He is stopped by Kisuke Urahara and Yoruichi Shihōin, who proceed to make sport of Yammy, easily deflecting his attempts to attack them. Before they can inflict any major damage, however, Ulquiorra steps in and forces Yammy to retreat. The two then return to Hueco Mundo, having completed their mission.

Yammy has his arm reattached in Hueco Mundo and heads off to Karakura Town along with Grimmjow Jeagerjaques, Luppi, and Wonderweiss Margera as part of the second assault on the material world. Yammy starts fighting against Tōshirō Hitsugaya, but his opponent is taken on by Luppi, leaving Yammy with no one to fight. Later, he performs a devastating surprise attack on Kisuke Urahara. However, Urahara manages to survive and seems unharmed, which confounds Yammy. After an exchange of blows, Urahara seems to have gained the upper hand, revealing he is using one of his inventions: a portable Gigai. He has simply been switching places with it the entire time. Yammy gets angry and claims that Urahara is looking down on him, but he is taken back to Hueco Mundo by a Negación beam before the fight continues.

Hueco Mundo arc
After Ichigo, Chad, and Uryū Ishida invade Hueco Mundo, he is seen at end of the table with the other Espada as they are briefed about the situation. He sits between Aaroniero Arruruerie and Barragan Luisenbarn. He complains about the intruders along with Aaroniero, Barragan, Szayel Aporro Granz and Nnoitra Jiruga. He is later seen when he senses Aaroniero has been killed, but surprisingly just scoffs at this bit of news.

Fake Karakura Town arc
He is seen recently, leaving his quarters after eating, finally deciding to act on the invasion of Las Noches. After Loly and Menoly begin torturing Orihime, Yammy suddenly appears during Ichigo and Ulquiorra's fight, hoping to help Ulquiorra fight Ichigo, knowing that the latter got stronger. Ulquiorra, however, refuses help, telling Yammy to either go back to sleep or deal with the invading Captains. Yammy then notices Loly and Menoly and knocks the latter through a wall, despite neither of them making even the slightest hostile move, even though they backsassed him in agreement of Ulquiorra's judgement. He moves in to kill Loly as well, but she draws and releases her zanpakutō (comments that he can't see how she could have hidden it in her outfit). She tries to attack Yammy and threatens to kill both him and Ulquiorra, but Yammy easily defeats her. He then rams her through the wall and drops her body, mocking her for (apparently) dying so quickly. He asks Ulquiorra if he can kill Orihime, but Uryū Ishida arrives and shoots him in the shoulder, knocking Yammy down (but barely piercing his shoulder). Surprised by his appearance, Yammy tries to attack him, but a special arrancar landmine Uryū uses (developed by Mayuri Kurotsuchi) explodes, critically injuring him. He barely manages to hang onto the edges of the hole created by the explosion, but Uryū breaks his grip and explains that he destroyed all of the lower pillars on his way up to the throne room, stating that Yammy would fall on the bottom. He curses Ishida before falling through every floor of Las Noches. His current condition and whereabouts are unknown.

Powers & Abilities
Yammy is the tenth Espada in Aizen's army, which also makes him the weakest of the Espada. He has been seen using the basic abilities of an Arrancar, such as:

Gonzui: Yammy uses a unique suction ability to absorb the souls from the living called Gonzui. It affects a wide area, but people with even slight spiritual power (such as Tatsuki Arisawa) are able to resist it. Coincidentally, Yammy is the only arrancar shown using the technique thus far.

Cero: He can fire powerful red Cero blasts through his mouth, like many other high-class Hollows and Arrancar. He can also presumably use Gran Rey Cero.

Bala: Yammy can also fire Bala blasts through his fist, which are weaker than cero blasts, but are also much faster.

Garganta: Garganta is how Arrancar move to and from Hueco Mundo. Yammy has the ability to use this technique, as shown during the first arrancar invasion of Karakura Town. It literally tears open the dimensional fabric separating the worlds, revealing a tunnel of whirling, torrential energy that must be focused and solidified to create a discernible pathway.

Enhanced Strength: He also possesses superhuman strength, as seen when he was easily able to overpower Chad's initial Right Arm of the Giant form. His strength was also shown during the Fake Karakura Arc, when he easily knocked Menoly aside a few hundred feet, breaking through the wall inside the Dome of Las Noches. Yammy also defeated Loly after she released her Zanpakutō, and only attacked her using his fists, disposing of her in a few hits.

Hierro: Yammy was the first Espada, and arrancar to demonstrate hierro. Yoruichi Shihōin knocked Yammy unconscious for a brief moment, but sustained injuries to her left arm as a result of his hierro. Yammy's hierro is even strong enough to resist an arrow from Uryū Ishida's recent bow, and survive the explosion of Mayuri's landmine with critical injuries. The only time so far that Yammy's steel skin has failed him is when Ichigo Kurosaki cut off his arm during the first invasion of Karakura. This was done within the world of the living, so it may have simply been caused by the decrease in reiryoku backing up Yammy's durability; His skin would have been stronger in Hueco Mundo.

Zanpakutō
The name and released state of Yammy's Zanpakutō have not been revealed, as he has relied on his brute strength in battle, taking little interest in using his sword. It has a rectangular guard with two small squares on the shorter sides. When overpowered by Ichigo he is about to release his Zanpakutō, however, Yammy is halted by Ulquiorra who warns him not to do so.

Trivia
