The Last Trytans

What a birthday week! A lot of really weird things have been happening! Things like me making soccer balls move in strange ways and making it rain. Things like hearing voices in my head and making people do whatever I tell them to do; like, when I told my BFF to disappear and she did! How about my birthmark changing shape and color? Suddenly, I have a green trident on my shoulder and it burns awfully at times.
THEN, MOM TELLS ME I'M ADOPTED!
I'm not too surprised. After all, one of the voices in my head had already told me I wasn't even human! I'M AN ALIEN CALLED A TRYTAN. In fact, I'm the leader of the Trytans and I've got some amazing powers that I'm supposed to use to get rid of another alien race called Arkadians who are killing us off.
Oh yeah, did I mention I just turned THIRTEEN?
