Katara: Water

The waterbender weaves a stream of water from the ground, around him and then thrusts it towards the side.

Katara: Earth

The earthbender kicks the ground bringing up a large rock before he kicks it away.

Katara: Fire

The firebender twists around as she summons fire from her foot before doing a high kick to the ground and makes the flames spread.

Katara: Air

The airbender drops down and then with a circle of his arms he creates a blast of wind.

Katara: My grandmother used to tell me stories about the old days; a time peace, when the Avatar kept balance between the Water Tribes, Earth Kingdom, Fire Nation and Air Nomads. But that all changed when the Fire Nation attacked.

A map of the Four Nations is shone before flying through the mountains of the Earth Kingdom, before coming to where docked on a shore, five Fire Nation ships released their soldiers. With a jump forward and a palm thrust, the firebenders released a wave of fire.

Katara: Only the Avatar, mastered of all four elements. Only he could stop the ruthless Firebenders. But when the world needed him most, he vanished.

The Avatar, a man with a crown on his head and dressed in robes stands on a pillar of stone as he bent the four elements of water, earth, fire and air to show his skill in the arts of bending. After releasing a powerful disk of wind, he disappears from existence.

Katara: A hundred years have passed, and the Fire Nation is nearing victory in the war. Two years ago, my father, and the men of my tribe journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving me and my brother to look after our tribe.

Across the lands of the other three nations, the Fire Nation has laid destruction across everything in the war in flames. Four Water Tribe boats made their way from the village to go help in the fighting, leaving a young man and his sister to look after the tribe.

Katara: Some people believe that the Avatar was never reborn into the Air Nomads and that the cycle is broken, but I haven't lost hope.

Up close, the siblings looked worried as they watch their fellow tribesman. But behind her saddened eyes, the younger Water Tribe girl still had hope that things would get better.

Katara: I still believe that somehow the Avatar, or maybe he and a new hope will come to save the world.

A wormhole opened in the sky, and a large red reptile with wings, and black hair with green highlights fell out of it before crashing into the icy wasteland with what appears to be a gray dog on his back.

The Avatar and the Dragon

Jake Long, also known as the American Dragon, slowly regains his footing as he then looked around to see where in the hell he was. Then realized that he wasn't alone.

Jake Long: Fu, are you alright man?

The dog, known as Fu Dog, exploded out of the snow as he hugged himself and shivered like a leaf.

Fu Dog: C-cccccoooooldddd.
