Renshu

 was a bodyguard and mobster, hired by Chen Luo to protect him and do his dirty work. He appeared to be the leader of a group of Chen's thugs.

Renshu encountered the Thirteenth Doctor and her friends in 1972 when he was pursuing a young woman called Tung-Mei through a market in Hong Kong to capture her for escaping from Chen Luo and his son Shui Long, stealing Shui's pendant in the process. However, upon bumping into Yasmin Khan, Renshu got Yaz and Tung-Mei's pendants mixed up and took the wrong one while forcing Yaz, Graham O'Brien, and Tung-Mei into a car.

He escorted them to Chen's floating castle restaurant where he was ordered to correct his mistake, leading him to encounter the Doctor and Ryan Sinclair at Bruce Lee's house. A fight broke out, during which Ryan failed to pin down Renshu, forcing the Doctor to hand the pendant to him in return for Ryan's life. He gave the pendant back to Chen and later tracked the Doctor, Ryan, and Bruce back to the floating village of Aberdeen so they could be escorted back to Chen Luo and his alien affiliates, the Kalatra.

After witnessing the battle between Shui Long and Bruce Lee for the fate of Earth, he attempted to help back up Chen Luo in taking Bruce's life himself, but was immediately shoved into the sea by Graham and Yaz. (COMIC: The White Dragon)
