Appa flocked (Avatar The Last Airbender)

A buffalo like no other

Appa is the famous flying buffalo always accompanying Aang, the main character of the manga and cartoon Avatar, the last Airbender. Taking place in a world where people are divided into four categories, air, earth, fire and water, Aang is the avatar, the one who has the ability to master the four elements. When he learned of his destiny, he panicked and flew away on his faithful bison Appa. But caught in a storm, they found themselves frozen and preserved in an iceberg for over a hundred years. When they awoke, the fire nation had declared war. Appa continued to accompany Aang on his perilous missions to try to stop the war.
