Councilor Chang is a dragon from China just like Lao Shi as well as a dragon councilor at the Isle of Draco. She first appears in the episode "Dragon Summit" as one of Jake's examiners during the "Test of Flight" challenge. At the end of the episode her duplicity is shown as she is a double agent for the dark dragon and had been for centuries. In the Episode "Hong Kong Nights" it is revealed the she orchestrated the legendary battle between Lao Shi and the Dark Dragon in which Lao Shi emerged the victor. Later on in the episode she is seen leading Lao Shi into the sewers where she double crosses him in turn revealing her loyalty to the Dark Dragon, she traps Lao Shi in sphinx hair netting and summons her master, however she was defeated by Jake (who had enlisted the help of Trixie and Spud and a few magical creatures) to rescue Lao Shi. Her next appearance would be in the episode "Halloween Bash" where she along with her fellow councillors Klude (Arctic Dragon) and Andam (African Dragon) were captured by the Hunts Clan to be executed as part of Huntsgirl's initiation test. Chang returned in Nobody's Fu where she escaped from prison and had a sidekick named Bananas B. Chang appears again with Bananas B where they stole hydra scales and a phoenix feather and Chang pretty seems to know who Sun Park is. Again she is seen in Hong Kong Long with Bananas B and the Dark Dragon. She was hit by sphinx hair net in combat. After Chang was caught in a net made of Sphinx hair, she is probably dead, because she fell off the mountain or she was probably rescued and sent back to jail.Currently in the Spongebob series, Chang has returned to join the Fang Empire and her master, the Dark Dragon, in conquering all worlds in darkness for the glory of Makuta Teridax.
