Chinese Super-man previously lost his powers while fighting the Chinese Bat-Man and Chinese Wonder-Woman. No explanation yet is given as to why he lost his powers, and what triggered it to come back. It looks like it’s going to be used as a plot device for this character. Maybe DC finally learned that a character with overpowered skills is too much of a challenge to write, hence this handicap for Kong Kenan.
