Dark Dragon (ADJL)

The Dark Dragon is the true main antagonist of the animated series American Dragon Jake Long. He is a power hungry dragon who attempts to wipe out humanity and any other mythical creature who gets in his way.

He appeared twice in the first season attempting to offer a deal to Jake, whom he seems to have an interest in him, a chance to join him in conquering the universe, yet Jake refuses and defeats him with help from Fred Nerk.

He reappears in the second season when he kidnaps Lao Shi, Jake's grandfather to blackmail him into joining him and his minions. However, Jake, with help from friends and family, defeat him and he is seemingly killed when he gets crushed by rocks. However, he survived the crash, and he grabs Jake with his tail, hoping to take Jake with him through the portal. In the process, Rose cuts the tip of the Dark Dragon's tail, which gives Jake and Rose the chance to escape. The Dark Dragon, however, was not so lucky.

He is shown to be in league with Councillor Chang, a member of the Dragon Council.
