Clay (Voiced by Jeff Bennett and by David Kaye in the sequel) was the Xiaolin Dragon of the Earth. He fought evil to collect the magical Shen Gong Wu with the other Xiaolin warriors. His Wudai Weapon was the Big Bang Meteorang and his Wudai power was Wudai Crater. He was able to use his elemental powers with the Fist of Tebigong and the Third-Arm Sash. Clay was from Texas as a cowboy and worked on a ranch, being raised by his parents along side his sister, Jesse. He later traveled back for the Star Hanabi. He had not initially known that the Star Hanabi was his father's lone star. After Dojo told them that it was the Star Hanabi, he needed to get it from him but he couldn't go back with his friends to the temple or the Star Hanabi until he proved he was a man. Clay was a very mellow and patient, and did not get ruffled easily. There are few things that will make Clay angry, some being taking or messing with his hat, or harming his friends. Clay was also very honorable, trustworthy and chivalrous, and was somewhat old-fashioned in his ways. Clay used Tai Chi, referred to as "Old Man Kung Fu" by Raimundo. In his very first Xiaolin Showdown, Kimiko, Raimundo, and Omi did not have any faith in Clay winning against their nemesis, Jack Spicer, because of his patient maner and characteristics of his element. But Clay proved the other Monks wrong by using sunflower seeds to attract the bird in the showdown instead of aggressively attacking and harming the bird.
Clay, naturally, was also the strongest of the Dragons in training. Clay could often think of creative solutions to problems, and his patience was valuable to the other Monks. He always had a way to find the light of every bad situation. He took on the "big brother" role of the team, always protecting and caring for the other Monks. He was also a big eater, his first loyalty being to any food he laid his eyes on, particularly pork chops. Clay was very skilled with a lasso which he consistently used for snagging items, saving allies as well as capturing opponents.His chivalrous ways, Clay would never fight or hit a girl and therefore would not battle any female even if they are evil.
In addition to his elemental abilities and martial arts skills, he had other superhuman attributes such as:

With this attack his ability to manipulate earth was even greater than before.
