Oh! You are a navigational super-star! You need no device to tell you your position. You always have a clear and precise grasp of your place in the spacial relations around you, including depth or altitude, longitude and latitude, and more detailed things such as exactly how far you are from whatever surrounds you at the time, the directions to anywhere you've been before or seen a map of, and the distance between any two places you care to turn your attention to.

You are not only never lost, but you can gain a sense of where others are at and help them out without even laying sight on them -if a child is lost in the woods you can direct them out as soon as you have even a rough idea of where they are.

You can turn into a living stone statue. Due to this you are very strong but very heavy and eat a lot more than a normal person. Even as a human you are heavier that normal as your bones are thicker to facilitate the change.
Because you turn to stone you are more durable, so it is harder for people to hurt you.

You can turn any happy person into a depressive mess, just like you can send a sad person into a manic state. That's crazy. O.O

Your superpower is related to music; you can affect the world with your songs, changing how they view any subject or person, giving them energy or taking it away, filling them with purpose or putting them to sleep, engendering love or longing or anger, helping them create new breakthroughs in self-understanding or aiding them in self-delusion.

You have incredible senses, your sight and hearing are the obvious ones. You are incredibly caring and know just how to care for those around you.

You have the gift of purification; you can remove toxins and taints and poisons, and clear up pollution, and as a result you can visit anywhere in the world, and people pay your way and host you free because your mere presence makes everything around you better.

You have an all seeing third eye that can be used too see into peoples past and present. Still too young to be able to see into the future though, but you'll get there

You bring the power of peace. Those near you feel instantly safe and at ease; and anyone close to you finds it impossible to fight. They can still become impassioned, though, and you are often called upon to mediate debates and disputes.
In war-torn regions you bring a space of calm for people to recover (and prepare to flee when you leave).

Your presence is desired the world over!

You can steal the collors out of everything around you

You see through all illusions to the truth beneath.

Unfortunately, this means that magic shows aren't very interesting to you, and you don't tend to enjoy circuses much, or even movies with their special effects.

Still and all, you're amazing as a judge.
