UN and countries

You are adopted, but you are just like your UN father for some reason. He injected you with his genes, giving you wings and the will of fire, which means you have powers that only the English family possesses. At age 7, you were given the title of Guardian because they were being hunted by monsters and you protected them. Being the daughter of the UN, you were sought after, and the decision was made that you would be the Guardian from the shadows. Ten years have passed and you return to your parents, the UN and the FBI, after years in hiding to protect the country
