Tchang Zu was the Demon Sorcerer of Thunder. He was banished by the Immortal Cao Guojiu (however, the Immortal that is shown banishing him is a cripple with a crutch - similar to the Immortal Iron-Crutch Li Tieguai). Tchang Zu's portal is located in Hollywood, California. It is, ironically, contained within a door on a movie studio lot, and the Immortal who defeated him was known as an actor. After Tchang Zu's release, he sought to reclaim his palace, only to find it had been paved over into a parking lot. He then attempted to claim the Chinese Theatre for his abode, but was banished again by the Chans. Tchang Zu later confronted the J-Team in Demon World, Part 2 atop Hsi Wu's tower, but was banished thanks to Paco, who happened to have a pair of castanets. It's interesting to note that Tchang Zu had no dialogue in either part of the Demon World saga. The Immortal castanet containing traces of the Thunder Demon Chi was found aboard the Oceanic, a sunken ship. It was claimed by Drago, who took over the Space Needle for access to its storms, which could enhance the Thunder powers, but it was removed by Uncle. Drago absorbed the Chi later with the rest of the Demon Chi, and traces of it were invested in his cronies.
Tchang Zu's powers consist of mainly of the strength of throwing spear like thunderbolts and summoning storms. He is shown to be very aggressive and arrogant towards others, in particular Shendu, whom he was quick to attack upon Shendu's arrival in the demon netherworld in the episode The Stronger Evil. He also insisted Shendu refer to him as "master" whilst on Earth.
It is interesting to note that Tchang Zu's name seems to be pronounced as 'Tchung Zu' in Season 2, while it seams to change to change to 'Tchang Zu' in Season 5. This may be to accommodate Drago's pun "Tchang Zu. Tchang Zu very much."
