Actually this is the name of one of Avatar cartoon series (or something similar). It is gorgeous cartoon, where people have super skills, like water, fire, air and ground control, and only Avatar can control everything (this guy is on the picture).
I like to make analogy between this cartoon and triathlon. Sport - is a fairy world were runners are "Ground magicians", swimmers are "Water magicians" and cyclists are "Air magitians" (as triathlon doesn't have analogy for fire magicians, we'll skip it ;)). Those who possesses all of them are Avatars, or in our world - Ironmans.
