Protecting Chan Ho Yin
When Chan was kidnapped by a mysterious organization who sought to use Chan to further their own ends, Quan contacted Agent 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. Coulson and Agent Melinda May arrived in Hong Kong and, together with Quan, they raided the lab. He was found weak and with serious burns on his arms after being tortured.
However, despite Quan's attempts to bring him to safety, Chan was tired of S.H.I.E.L.D.'s insistence on hiding his abilities and had gone mad due to the torture he had suffered. Chan used his power to burn a hole through Quan's heart, killing him instantly.
