In the first LUK SIU FUNG story (THE MYSTERY OF THE GOLDEN ROC KING'S TREASURE), there was a character named Lau Yu Hun, an assassin/bodyguard in the employ of Seung Gwoon Fei Yin. Some time in his past, Lau Yu Hun lost both his hands in a mishap. Therefore, during his appearances in LUK SIU FUNG, he used a set of prosthetic hands.
I always found this guy amazing because of the variety of prosthetic hands that could be installed onto his arms. This guy was Edward Scissorhands years before that movie introduced that freakish character (who, when I think of it, was quite Lau Yu Hun-like on several levels). Lau Yu Hun's default hands were an iron hook on one arm and an iron ball on the other. The hands, however, could be replaced with any number of different weapons and tools. When Seung Gwoon Fei Yin sent Lau Yu Hun to attack Luk Siu Fung (hoping that Luk would kill Lau), the usual hook had been replaced with a sword.
I would have liked to keep this character around longer just to install different variations of prosthetic hands onto him.
