Neopolitan

Neopolitan, best known simply as Right-Hand Illusionist, is one of the antagonists of the anime-styled RWBY game series. A master of disguise, a peerless fighter, an escape artist, are among the many things one can say to describe Neo. Cruel, vicious, and sadistic are some others. But actually, she is sweet, petite, loving and loyal... if you're a Dum-Dum. More specifically, HER Dum-Dum.

She has an umbrella called Hush, which is capable of blocking powerful blasts with a hidden blade in its handle. Her illusion-based Semblance, "Overactive Imagination", allows her to generate disguises for herself. In battle, she would continuously smile, which serves as a way of taunting her opponents.

History
The right-hand woman of Vale crime boss Roman Torchwick, much of Neopolitan's past is shrouded in mystery, none of which is helped by the fact that she's mute. First encountered by Team RWBY as they pursued Roman and the Faunus extremist group known as the White Fang, Neo's illusions facilitated a clean escape for her boss. A disasterous attempt from Yang to battle Neo later nearly ended fatally for and put on display just how out of RWBY's league Neo was. Outwitted by Ruby Rose during the Battle of Beacon, Neo was powerless to save Roman from being killed, leaving her with an intense hatred and a craving for vengeance against everyone she felt was responsible for his death, with Cinder Fall, and possibly Ruby, at the top of the list.

In battle Neo is something of a dancer that twirls, spins, and flips all about as she weaves in attacks. In addition with her semblance capable of producing illusions so convincing one can physically clash with them makes Neo is almost impossible to pin down. Finally her parasol, Hush, is capable of serving as a shield and contains a hidden blade in the tip making Neo more than capable of throwing down with your average Huntress even without Dust.

Trivia

 * Although she doesn't talk, Neo isn't mute, as confirmed by Gray G. Haddock during the RWBY aftershow.
