The guardian of the temple dies and a new Golden Dragon must be chosen to replace him; two twins, Ang and Ling, compete for the privilege.

Ang returns to the dojo and finds Ling, who is still upset about not being chosen as the Golden Dragon. The Zodiac Master approaches Ling and shows her that she can become a dark version of the dragon, called the Shadow Dragon.

Ang becomes the Golden Dragon, protecting the 12 Zodiac Temples, while Ling as Shadow Dragon swears to destroy them.

Ang and Xuan Chi guard the ox and golden dragon power bands to keep Ling and the Zodiac Master -- who already have the dog and ram power bands -- from harnessing all the powers of earth.

The Zodiac Master gains control of the dog and ram power bands, allowing him to generate earthquakes.

After Ang's temper gets him into a fight at the dojo, Master Chin takes him and Xuan Chi to a new sensei to learn some discipline.
