Monitoring Chan Ho Yin
Quan Chen was stationed in Hong Kong, China by S.H.I.E.L.D. where he was assigned as case worker for "Registered Gifted" man, Chan Ho Yin, a street magician who developed pyrokinetic powers. Quan would check in with Chan every couple of days. When Chan was kidnapped by a mysterious organization who sought to use Chan to further their own ends, Quan contacted Phil Coulson. Chan was able to give them the information needed to learn who was behind Chan's disappearance.
Coulson's Team was able to locate the lab where Chan was being held, and Quan joined Coulson and Melinda May in raiding the facility. The agents located Chan, who was severely weakened and burned, and Quan approached Chan to bring him to safety.
However, Chan had gone mad from the torture inflicted upon him and became hostile to S.H.I.E.L.D.'s intervention. While attempting to provide aid to Chan, Quan was instantly killed when Chan turned on the S.H.I.E.L.D. team and burned a hole through Quan's torso.
