*****Notice! Firebird's backstory is still being tweaked...I'm going with what I made for her years back when I was trying to do a comic****
Firebird was born back when the Dark Legion was wreaking havoc upon the towns. Sadly both of her parents have passed on and she was placed under the watchful eye of Grandpa Goodfellow, and old friend to the parents.
Once she turned 16 she decided to leave her town in the Rainforest of Mobius to meet Sonic, whom she only knew about through stories passed down. During her journeys she began to meet up with various Mobians and decides to make a team called the Future Freedom Fighters.
Firebird is also classified as an elemental. She holds onto 'elemental stones' which give her the power of that element. Elements that she can use are: Fire, Water, Wind, Thunder, Ice, Earth, Sun, Moon, Holy, and Demon. Her appearance will change with each element same with her temperment. Out of all the elements, Demon is not recommended to be used. She will become manipulated and it is very hard to change her back.
