Chang-Pan (Chang)

"You indeed go over to human. I shall kill you!"

- ——Chang-Pan attacking Xiao-Bai

Chang-Pan was a snake demon and the apprentice of Snake Mother. He was a senior apprentice and eager to prove himself in front of his master and fellows. When Xiao-Bai was sent to assassinate General, he felt that he was looked down upon by his master. However, after Xiao-Bai failed in the assassination, he knew that his chance had come.

It seemed that Chang-Pan wasn't powerful enough to have a human form, or his hatred against human was so strong that he preferred a more demonic look. In his half-snake form, Chang-Pan's upper body was a strong man with lots of spikes and scales, and he also had a strange chest tattoo. His snake half was a gaint rattlesnake tail.

In his snake form, Chang-Pan was a gaint dark rattlesnake with a spiky head which was similar to Atheris hispida (bush viper).

Personality
Chang-Pan was a loyal apprentice and was eager to please his master. He was green with envy that Xiao-Bai was chosen by Snake Mother to assassinate General. So when Xiao-Bai had failed in her mission, he was the first one who questioned Xiao-Bai's loyalty.

Because he was a senior, Chang-Pan was respected and feared by other snake demons. However, the fear of others gave him a false impression. He believed that he was much stronger than others which was not necessarily true.

Abilities
Chang-Pan preferred using his snake form in the combat. In the movie, he temporarily stop the flow of the river with his magic, then transformed into his snake form and attacked Xiao-Bai. In his snake form, he became much agiler, and primarily used his bite as a weapon. He could also rattle his rattle tail to create a distracted sound wave and daze his enemies for a moment.

It seems that Chang-Pan's blood was perfused with some sort of poison or ice magic. When Xiao-Bai slayed Chang-Pan, his blood dropped on her and instantly froze, when exposed to air, which almost killed Xiao-Bai.

Trivia

 * As other snakes' names in the movie, "Chang-Pan" is also a nick name. It means "always coiling".
 * Although the idea of mixing a rattle snake and a bush viper together is cool, both snakes aren't native species in China or East Asia.
