Eight Demon Sorcerers

The Eight Demon Sorcerers, also known as the Demon Sorcerers, are a group of 8 ancient demons with mystical powers and the main villains from the second season of Jackie Chan Adventures.

History
The Eight Demon Sorcerers are 8 demon siblings, who all ruled different parts of Earth, but were then banished to the Demon Netherworld by the Eight Immortals, who used the Pan Ku Box to seal them away. Shendu was the only one who escaped banishment, only to be imprisoned in a statue form by the warrior Lo Pei.

After Shendu is killed by Jackie and Jade Chan, his spirit returns to the Netherworld, where his brothers demand that Shendu releases them immediately. Shendu attempts to possess Jackie Chan, but accidentally possesses Valmont instead, then forces the Dark Hand to work for him once more to release the demons.

He does release his brothers, but they are all banished back again.

After all portals are sealed and Shendu is exorcised from Valmont, he decides to use the Book of Ages to change history. This time, he successfully possesses Jackie, then travel to Australia, where the book is located. He is followed by Jade, Uncle and Tohru, but they couldn't stop him, as history is completely rewritten with the demons ruling Earth again. Jade is the only one to retain her memories, as she had accidentally tore a page of the book that spoke about herself. She manages to convince Jackie and Uncle to help banish the demons, eventually going to Australia to set things straight again, but not without being followed by Shendu and the remaining Demon Sorcerers. The demons are all banished again and history is restored to normal.
