Neopolitan

Neopolitan, also addressed as Neo, is an antagonist in the world of RWBY. She is the right-hand woman of Roman Torchwick and an associate of Cinder Fall.

Appearance
Neo, themed after Neapolitan ice cream, has the appropriate trio of colors in her hair and on her outfit. Her hair is half pink and half brown, with white streaks in the pink half.

Neo's natural eye color changes between brown, pale pink, and white, and they can alternate coloration in differing combinations, with this ability apparently being entirely under her control. Because of this, she tends to temporarily have a condition known as heterochromia iridum, where the eyes of a subject have two different colors. In her case, it is complete heterochromia, where one iris in its entirety is a different color from the other.

Neo wears a white jacket with a pink interior, brown pants, and gray boots with very high heels. Under her jacket is a black corset, curved in the middle and at the bottom, exposing her hips. She also wears a multitude of necklaces, which hang haphazardly around her neck.

Neo is also rather diminutive in stature, compared to the rest of the main cast, including Ruby Rose, the youngest known character, as shown in the height chart presented by Monty Oum. This is demonstrated in No Brakes, when she stands off against Yang Xiao Long, as Neo is only able to reach her chin in overall height.

Volume 2
In Painting the Town..., Neo is seen at a gathering of the White Fang, accompanying Roman Torchwick as he addresses the group; providing them with new weapons his "associates" had acquired for him. She later saves and aids Roman in his escape following his defeat at the hands of Team RWBY.

In No Brakes, Neo is seen on a train carrying large amounts of explosive cargo, once again aiding Roman. After Team RWBY boards the train, Neo ends up confronting Yang Xiao Long, allowing Weiss Schnee and Blake Belladonna to pass by Neo without consequence. However, after a brief, rather one-sided fight, Neo bests Yang and attempts to kill her via a dagger in her umbrella. However, before she can, Raven Branwen appears, prompting her to flee.

Volume 3
In Round One, Neo is later seen participating in the Vytal Festival combat tournament. She conceals her identity by changing her appearance drastically: she wears a predominantly black outfit and also changes her hair and eye colors. In the tournament, she competes as part of a team with Emerald Sustrai, Mercury Black and Cinder Fall. The team has no trouble during their first match, in which Neo is seen mercilessly stomping on a hapless opponent.

In Beginning of the End, after Mercury fakes a broken leg, Neo and Cinder, disguised as paramedics, evacuate Mercury via Air Bus to an unknown location.

In PvP, Neo invades an Atlas ship and dispatches the guards before freeing Roman from his cell, returning to him his trademark hat and Melodic Cudgel.

In Battle of Beacon, while aboard an Atlesian Airship, Neo hands Roman a scroll with Cinder's virus on it. Roman plugs it in, infecting all of the AK-200 soldiers with a hostile AI. When Roman hears something crash into the top of the airship, he instructs Neo to find out what it is. Neo nods and leaves the room, heading to the airship's roof.

In Heroes and Monsters, once she arrives there, she uses her power to change back into her original outfit and report to Roman with a text from her Scroll, before engaging in battle against Ruby. She easily dodges the swings of Crescent Rose and shatters in an illusion, before Roman intervenes in the fight. Together, the two gain the upper hand on Ruby, with Neo landing a roundhouse kick, sending her to the edge of the airship. As Neo slowly walks towards Ruby, dragging her blade and holding her at swordpoint, she is immediately thwarted when Ruby opens her parasol, causing the winds to blow her away from the airship, leaving her at the mercy of the raging winds - and the flying Grimm.

Whether or not she survived remains to be seen.

Personality
Neo appears to exhibit a stern, business-like demeanor at the White Fang meeting. However, when intervening to help Roman following his defeat, she wears a self-assured smile and politely bows to Team RWBY, showing confidence on the battlefield. Neo's confidence was also seen in her fight with Yang, smiling throughout the entire fight, whilst silently mocking and taunting her as well. She displayed confidence before the fight, not only against Yang, but also Weiss and Blake, where even outnumbered she herself was ready to fight them, revealing herself instantly.

Neo is also shown to have a slightly psychopathic and cruel side, as seen in her smile as she prepares to stab Yang. However, she does seem to exhibit fear and hesitance when she knows she's outmatched, fleeing if her opponent proves to be as such. This can be seen when Raven Branwen appears and engages her on the White Fang cargo train.

Skills and Abilities
Neo's weapon of choice is an umbrella containing a cane sword, a long, thin sword blade hidden within the length of the umbrella's tube which has a hole on the top end of the it, with the crook handle serving as the hilt. The canopy of her umbrella possesses high defensive properties, demonstrated by its ability to block an incoming blast from Yang Xiao Long's Ember Celica.

Neo also appears to be capable of creating illusions, which she used to help Roman escape from Team RWBY, by making it appear as though they both remained on the ground, thus allowing them to board a Bullhead as Yang shattered the illusion. The nature of this illusion is unknown, although visually it resembles a screen of glass with a projection of her and Roman. Her radically different appearance in Round One also implied her illusions extend to changing her appearance, although it is also possible she disguised herself by more conventional means.

Neo is shown to be a highly skilled combatant, able to defeat Yang in a one-on-one fight, seemingly playing with her opponent as she was able to defeat her without taking anything more than a glancing hit. In close quarters combat, Neo utilizes her umbrella's open form in parrying Yang's attack which opened her up to counter blows. Neo also displays incredible reflexes and speed, dodging several of Yang's attacks with ease, even when holding her umbrella in one hand.

Neo also showed herself to be very acrobatic and exceptionally skilled in hand-to-hand combat, relying on her agility to dodge and misdirect enemy movements and attacks, before retaliating with her own kick-based attacks, as her combat style is mostly relied on kicks, similar to that of Mercury's combat style. She was also shown to have an ability that seems to allow to her to teleport away in a white flash, as seen when Raven showed up to aid Yang.

Trivia

 * Her name and appearance reference Neapolitan ice cream, which is a combination of strawberry, chocolate, and vanilla flavors. These colors correspond to her color scheme.
 * From the 8th to the 11th of July 2014, Monty hinted at this long before the character's first appearance by tweeting pictures of Neapolitan ice creams.
 * Neo- (νεο-) is also a Greek prefix, meaning "new." In English, neo- is also used as a prefix to denote something that is contemporary, recent, modern, or new. The word Neopolitan itself derives from the Greek Neápolis (Νεάπολις), meaning "new city." Neo also means 'young' and 'immature' in Greek, usually in medical terms.
 * Monty stated during the August 21st Rooster Teeth livestream that Neo's design is partially based on a presentation-play cosplay of Torchwick made by one of his friends.
 * Neo, according to a photo Monty posted on his Facebook, is the shortest person of all characters in RWBY.
