Felicity Smoak

Felicity Smoak is a main character on CW series Arrow and a part of the Arrowverse.

Character
Felicity is a brilliant scientist, who spent her youth as a hacktivist, which she quit after her boyfriend at the time was arrested. She is arguably at genius-level, which is paired with an innate social awkwardness and tendency to delve into work rather than social engagements. This all changes when Felicity becomes a part of Team Arrow as Overwatch and forms lifelong bonds with her comrades-in-arms Green Arrow, Spartan, Black Canary and Speedy, among many others. Felicity is considered an invaluable part of the team and in many instances provides a reality-check balance to Oliver, as she is one of few who do not falter in the face of his dismay.
