Constable Neyla makes her only appearance in the second game of the Sly Series: Sly 2: Band of Thieves.
Neyla was, at one point, an ally to both the Cooper Gang and to Interpol. As the storyline unfolds, Neyla would betray both groups, and showed that she was only looking after herself and had selfish intentions. Neyla's ultimate goal was to achieve immortality. To do this, Neyla planned to steal all of the Clockwerk parts for herself, and to basically, become Clockwerk. Neyla ultimately achieved this goal after betraying her mentor, Arpeggio.After Arpeggio succesfully gathered all the Clockwerk parts, Neyla turns her back on Arpeggio and kills him. Neyla then not only steals the Clockwerk parts, but she merges herself with them, becoming Clock-La.
Neyla grew up in poverty as a child, in New Delhi, India. Eventually, Neyla somehow scammed her way into a British University, and formed a "homework ring" where she used her skill of persuasion to get other students to do her homework for her. Authorities eventually caught Neyla. However, rather than arrest Neyla, the was offered a job at Interpol because they were impressed by how persuasive she was and saw her as a valuable asset to the police force.
Neyla had strong trust within both Interpol, the Cooper Gang, and the Klaww Gang. With these stakes in both sides of the law, it made it much easier to for Neyla to get her hands on the Clockwerk parts. Neyla uses everybody to benefit herself and to propel her to her goal.
