Maddie Nolen was born in Noxus, where she became indoctrinated into the Noxian beliefs at a young age. At some point, she joined Ambessa Medarda's forces, before being chosen to be a sleeper agent for her and sent off to Piltover as a plant waiting to be activated should the need to seize control of the city ever arise. Once in Piltover, Maddie enlisted in the Piltover Police Department, eventually becoming an elite Enforcer.After Vi's evening of drinking with Loris on the street, Maddie introduces herself to Vi. Vi assumes Maddie is there to be an aggressor, but she is surprised when Maddie compliments her and relays Caitlyn's positive opinions of her. At the attack on the memorial, Maddie was temporarily captured by a Chem-Tank but was freed by Steb. Maddie would later join Caitlyn’s strike team, the other members being Caitlyn, Vi, Loris, and Steb. She would later infiltrate Zaun along with the Strike Team but would ultimately be ordered to return to Piltover along with an injured Loris, Steb, and a Zaunite prisoner, Heenot. She was in Piltover by the time The Grey was momentarily diverted into the city by Jinx.While undercover, Maddie's overall demeanor was perpetually optimistic and enthusiastic, radiating warmth and positivity wherever she goes. She was always ready with a smile and encouraging words. She was very eager to learn and please her superiors, especially Caitlyn.Maddie is a young woman, in her early 20s, with short, choppy orange hair that falls just past her chin, grey-blue eyes, and a spattering of freckles across her nose and cheeks. She has a heart-shaped face with naturally rosy cheeks and usually a warm smile. She usually wears her police uniform with pride, but while off-duty in Episode 4, she is seen in a white un-buttoned blouse.
