About me: Master Swordsman: As a former Espada, Nelliel has a great deal of experience in fighting, showing hardly any effort in her advanced use of swordsmanship. Her body flows elegantly when engaging in combat, so finely tuned that she can stop her attacks at a moment's notice, and subsequently execute lethal attacks with absolute precision. She easily defeated Nnoitra, who is a highly proficient swordsman in his own right, several times.
Expert Hand-To-Hand Combatant: Even without the aid of her Zanpakutō, Nelliel is quite a skilled fighter. During her battle against Nnoitra, she was able to skillfully dodge and counter his attacks. She also used her swordsmanship in conjunction with her hand-to-hand combat skills.
Sonído Master: Her speed has greatly increased as well, fitting with her former position. She was able to repeatedly sneak up on and effortlessly avoid Nnoitra with her speed. She easily transported the badly hurt Ichigo to a safer place during one of Nnoitra's attacks.
Cero Doble (重奏虚閃 (セロ・ドーブル), Sero Dōburu; Spanish for "Double Zero", Japanese for "Heavy Performance Hollow Flash"): She retains her attack absorption ability in her original form, but now performs it with greater ease. According to Nnoitra, Nelliel's specialty is to absorb an incoming Cero and fire one of her own while returning it, thus creating a potent Cero Doble. In her original form, the force(s) of the Cero Doble is augmented greatly, since she rebounds the attack while blending it with her own Cero, which is pink in color and drastically increasing its power.
Hierro: Nelliel, while in her original form, has Hierro befitting the strength of an Espada. It is strong enough to allow Nelliel to counter Nnoitra's blade with a kick and show no signs of injury.
Enhanced Strength: Her strength is greatly increased, fitting with her former position. With her great physical strength, Nelliel can fend off attacks from gigantic weapons like Nnoitra's, launch her opponent several meters away with a single punch, and effortlessly slice through the Hierro of an Espada-level Arrancar opponent with one swing of her Zanpakutō. She is also capable of stopping Nnoitra's Cero barehanded.
Immense Spiritual Power: As the former third Espada, Nelliel has a grand amount of spiritual energy, powerful enough for her Fracción to sense it from a large distance. Renji even stated that her spiritual power was close to Ichigo's, confusing the two for a moment. Her Reiatsu is pink.
High Intellect: While in her original form, she is shown to be quite intelligent. Having a great understanding of combat and its forms, and the methods behind an opponent's skill and intentions, she can discern personalities easily. She also has a philosophy on life that provides a code of honor, respect, and mercy. However, her childlike antics can sometimes block her intelligence. At one point, she latched onto Ichigo, who was clearly injured, to the point where he passed out, then latched onto him again.
Gamuza's sealed form.
Gamuza (羚騎士 (ガミューサ), Gamyūsa; Spanish for "Chamois", Japanese for "Antelope Knight"; Viz "Capricorn Knight"): Her Zanpakutō has a green sheath, a light green hilt, and a tsuba that resembles a pair of crescent moons joined together at the back.
Nel in her release form.
Resurrección: Its release command is "Declare" (謳え, utae; Viz "Praise"). Nel holds her Zanpakutō up in front of her horizontally and calls out its release command. The Zanpakutō glows as a hazy smoke emanates from it. She calls out the name of her Zanpakutō, and the glow intensifies into a huge burst of spiritual energy that covers the surrounding area. In her new form, Nel takes the form of a brownish-green ibex-like centaur, complete with a black horse's tail. Her Hollow mask's horns become longer and more curved, framing the sides of her face, particularly the cheeks. The crack on her mask also closes up, although the missing teeth remain. Her shoulders are covered by white spaulders that come across her shoulder blade to her neck. She has white elbow guards and white gauntlets. The parts of her arm that aren't covered by armor are covered by a black material, which also covers her hands. There is a white ring at the base of her tail. Her sword is replaced with a double-sided lance. These features grant her the overall appearance of a medieval knight or jouster.
Resurrección Special Ability: The only attack she has used in this form so far is Lanzador Verde.
Enhanced Strength: While in her released form, her might increases further.
Enhanced Spiritual Power: While in her released state, her spiritual power increases significantly.
Lanzador Verde (翠の射槍 (ランサドール・ヴェルデ), ransadōru verude; Spanish for "Green Lancer," Japanese for "Jade Lance"): Nel throws her lance at her opponent with extreme speed. As it travels through the air, it begins to spin and build up spiritual energy. When it reaches its target, it acts as a drill, inflicting extreme piercing damage. The technique is powerful enough to push back Nnoitra and break his Zanpakutō, which he was using to block the attack.
