Agent Kwan Chen was a family man and an agent of S.H.I.E.L.D. based out of Hong Kong.

Chen was assigned as case worker for "Registered Gitfted" man, Chan Ho Yin, a street magician who developed pyrokinectic powers. Kwan 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, Kwan contacted Agent Phil Coulson. Kwan, Coulson and agent Melinda May raided the lab where Chan was being held and released him.
