The Dark Dragon

The Dark Dragon is an extremely powerful, and evil Dragon. He is considered the number one threat to the magical community and an enemy of non-magical people. He replaced the Huntsman as the primary villain for the last episodes of Season 2 in American Dragon: Jake Long. He is voiced by Clancy Brown.

History
The origins of the Dark Dragon are unknown, but he is the first known dragon in history to ever turn evil. Being the Dark Dragon, his color is black with red eyes, although it is unclear if his appearance is his natural one or if he chose the coloration upon choosing evil. He was also usually seen in the dark and shadows. It is unclear if Dark Dragon ever had, or can even make, a human form, or if he is draco-locked in inverse fashion to how some dragons are humani-locked. Certainly, he has never been seen in human form; however, if he does have or can make one, then he has the perfect way to "hide in plain sight" as no knows what he looks like.

He could conjure dragon-like shadow creatures called Shade Demons, or Shades, to serve as his minions. Few dragons had faced him and lived. The last known prior to Jake was his own grandfather. The Dark Dragon's goals included assembling an army of evil magical creatures to destroy humanity and take over the Earth. He felt magical creatures, particularly dragons, to be superior to humans and should instead be the dominant species on Earth, ridding the world of humanity. It maybe because he saw in himself, and dragons as powerful, as having the right to rule. Or perhaps views humans as inferior, fearing they may cause the extinction of his kind, such as were the overt goals of the Huntsclan; although after the wish destroyed the Clan, he would no longer even remember them. He has been willing to kill any dragon and any other magical creature which got in his way or failed to agree with his beliefs.

Jake encountered him several times in his brief career to date, whom he seemed to have an interest in. During their first meeting, he offered Jake a chance to join him. In their second encounter, the Dark Dragon was defeated by Jake and his friends and was seemingly destroyed. However, much later, it was finally revealed Chang not only meant to resurrect him, but had helped imbue him with many dark powers. Through the use of yet another spell, albeit delayed until after the area had been vacated, Dark Dragon was returned to life and brought back to power.

In the finale of the Dark Dragon's schemes, he captured Lao Shi, in order to blackmail Jake into betraying the dragons of the world. After the ensuing battle royale, Chang and Bananas B were defeated along with the Shade Demons which were destroyed by Johnathan Long. However, the Dark Dragon remained unmatched until Rose returned to help Jake fight him.

When the temple they were in began its disappearance for, according to Fu, another one thousand years, everyone vacated the area. However, Rose became trapped within, prompting Jake to attempt a rescue. As the Dark Dragon was caught in the pulled of the closing portal, he grabbed Rose's ankle with the tip of his tail before she cut it off, freeing her and Jake to make their escape in at the last second. The Dark Dragon was pulled into another dimension where he should be imprisoned for one thousand years.
