Robin is a woman easily lost in a crowd.  Of average height and not so pretty that you're likely to notice, she often wears looser clothes that camouflage her true physique (which is fairly lithe and muscular).  Her hair is cropped fairly short and left it's natural color.  She's often seen smiling, looking around, with a canvas backpack over her shoulder, almost looking like a tourist.

When speaking with her, it's easy to get the sense that she cares about you and maybe even wants to help out.  Around the office, she has often brought in donuts to share or small bouquets for the secretaries and minor functionaries, letting them know they're appreciated.  She's good for picking out small but meaningful gifts for nearly anyone she knows.

She's rarely seen with much tension in her features, but mostly when discussing the very wealthy and the corporations that keep them that way.

Only her team and supervisors know about her dexterous skills on a building's facade or with a (seemingly) locked door.
