Hak Foo

Hak Foo is a recurring villain from the Jackie Chan Adventures. A very strong fighter always in pursuit of power, he is first hired by the Dark Hand to help retrieve the Pig Talisman, along with Tohru. He was the first to beat Jackie Chan in a fight, but he was then beaten by Uncle Chan, who was using the powers of the Dog Talisman which granted him immortality. He manages to get the Pig Talisman but loses it to Uncle and Jackie. After the defeat of Shendu, Hak Foo joins permanently the Dark Hand as a replacement for Tohru, helping in the search for the portals to release the brothers of Shendu.

After the search for the portals, Hak Foo goes on his own in search for power. He attempts to steal the Osiris Bracelets, which Jackie had found in one of his expeditions. Both him and Jackie end minimized due to a spell made by Jade, but Hak Foo gets the bracelets, using them to grow an extra pair of arms. He is unable to use them tough, as he is trapped into a glass jar.

He would appear again some time later, challenging Daolon Wong and his slaves, who were none other than the Enforcers. Daolon turns him into one of his slaves as well, but he becomes happy with this however, as he is granted unlimited power. He is returned back to normal after Uncle Chan uses a spell that strips Wong of his powers, and ends arrested along with everyone else. Wong attempts to summon Shadowkan with improvised ingredients, but accidentally releases Tarakudo from his slumber. Tarakudo takes Hak Foo and the Enforcers out of jail and makes them his henchmen, to help him find the Oni Masks that trapped his generals. He is never seen after the defeat of Tarakudo until the final episode, where he had become a freelancer along with the Enforcers, as he had enough of being a bad guy, helping in the final fight against Draco.
