Kyle Rondart

An agent of Fei Wong Reed, first introduced in Jade country as the good doctor who was helping the village with their problems around the time the children started vanishing. He seems kind and sincere at first, but we later find out that through hypnotism he was the one that sends the children (most of them his patients) to the old castle to dig out Sakura's feather. He re-appears in Piffle World as the very same person, knowing that Syaoran and his friends will likely assume he is just another incarnation of himself. (Source: Wikipedia)
