Marcy Kappel is the tritagonist of Spies in Disguise. She is a skilled security forces agent who mostly pursues Lance Sterling throughout the majority of the movie after Lance was framed for betraying the H.T.U.V.
She was voiced by Rashida Jones.
Marcy is an African-American woman who has dark brown hair, thick eyebrows and green eyes.
In her casual outfit, Marcy wears a green long-sleeved collared shirt, black jacket, and black pants.
Whenever she is out in the field with her fellow agents, Marcy wears a skin-tight gray and blue shirt and pants.
Marcy possesses a strong sense of justice who has lot of respect for rules as well as being no-nonsense and straightforward. Although she looks serious and blunt on the outside, Marcy is actually an amicable and magnanimous person deep down; this is evident during her mission at Venice where she comforted Walter after revealing to him that his mother sacrificed herself trying to protect her people.
- Martial Arts: Marcy showed her martial arts skills when she fought and restrained Killian.
- Driving: Marcy does a pretty good job of keeping up with Lance's spy vehicle right up until it takes a jump off a bridge.
- She knows Walter's mother, Wendy, as revealed when she confronted him in Venice, Italy. It is possible that Wendy inspired her to become an officer and a secret agent, as due to being a young woman in the present, she may have been a teenager when Wedny died in 2009.
- Due to chasing Lance and Walter for most of the film, she can be considered as a hero antagonist, as she did believe she was doing the right thing until she found out that Killian framed Lance.
