Forever Girl

A Forever Girl (or Forever Boy) is a child born pure of heart that is magically made to live forever as a child.

Creation

When a child is born, if it has a very pure heart, they decide that if it should be made into a Forever Child, so their pure heart will not be impacted by the faults of adulthood. It is unclear who "they" is.

Powers

A Forever Girl (or Boy) is one of the most sacred and magical creatures in Foon. They rival the Great Blue Tiger for their rarity and power. Forever Girls (and presumably, Boys) have two main powers, other than their eternal life: they are conduits for powerful prophecy, and once in their lifetime, if their heart is true and pure, they will be granted one wish.
