My people are called mutants and we're born with the potential. Some of us are different right from birth. My brother was born blue and got abandoned in a river by our mother to save her own hide. The rest of his abilities came about later, like it goes for most of us. What we can do varies from person to person.
For flying, it depends a lot on the type. Sometimes you're being lifted by an invisible force, others it's like causing two magnets to repel against one another that lets you glide. Sometimes it's heated, like you're a fireball hurtling through the air. No matter what though they're all freeing.
Not having them makes you feel unwhole, like part of you ain't there no more. It hurts.
