Long ago, the four nations lived together in harmony. Then, everything changed when the fire nation attacked.
Show the map of the four nations and then a close up of the fire benders tossing fire towards their victims.
Only the avatar, master of four elements, could stop them, but when the world need him most, he vanished.
An old avatar display its mastery of the four elements and when it comes to display air he vanishes from the view.
A Hundred years passed, and my brother and I discover the new avatar, an airbender named Aang.
Sokka and Katara find Aang frozen in the iceberg as his eyes are still glowing.
But also, four Hunters from another world called Gon, Killua, Knuckles and Shoot.
Shows Gon, Killua, Knuckels and Shoot laying down on the snow all weak.
And although Aang airbender skills are great, and the Hunters nen powers are Incredibles, they still have a lot to learn until they can save anyone.
Aang display its airbender technique for Gon and Killua in joy until they hit face first into a totem. Much to Knuckles and Shoot disappointment.
But I believe Aang and the hunters can save the world.
Shows Aang, Gon, Killua, Kncukles and Shoot looking at the top of a mountain in wonder and a tittle popped out in the sky.
