Chi-You's thralls

Chi-You's Thralls are innocent humans from the Ghostbusters' universe, who are possessed and transformed through Chi-You's power. They are his first line of defense, and are frequently used against the Turtles and the Ghostbusters.

Desiring an army of warriors, and with Casey Jones as a basis, Chi-You transformed two hockey teams into bestial thralls. The process of creating thralls took some of Chi-You's energy, but it also had the effect of creating a connection between them, which rendered him incapable of being sucked into the Ghostbusters' ghost trap unless the thralls were restored to their human state.

He sent the thralls into battle against the Turtles and Ghostbusters in Chinatown, but pulled them back when Michelangelo was able to free one of them. That evening, the thralls were unleashed on the Ghostbusters' headquarters, where April O'Neil and Ray Stantz had come up with a method of disrupting their connections to Chi-You. When the machine was triggered, the thralls were all freed.
