On the second day of Hogswatch, your Seanan gave away...

My superpower is empathic weather control. As a member of the Junior Super Patriots Southeast Division, they called me Tempest until I forgot my birth name. Marketing kept me out of most direct combat situations; after all, weather systems could form and take shape miles away from the action; as a short, chubby girl who looks terrible in spandex, they wanted me out of the public eye as much as possible. My powers work by projecting my base emotions into reality through meteorological phenomena: when frightened, I create thunderstorms to protect myself and my friends, when angry I freeze the world with snow and ice, when I'm sad it rains steadily for hours. If I want to be hidden, I summon fog. It takes a great deal out of me, physically and emotionally; after strong feelings and severe weather, I need to sleep for hours to recover.
That's how Marketing lost track of me. It's easy, if you are a seemingly weak girl who never disobeys, whose mind seems to always be just a little foggy, to tongue the pills and mimic what they want. After all, you would never do something so foolish as break away from the mold. The strength of will it takes to manage a tornado from a distance so that no innocent bystanders are harmed is immense; fog is fickle and burns off in the sun--holding it in one place against wind and sun takes a strength no one pays attention to until it's too late. Snowstorms in the height of summer can only mean trouble. Before my eighteenth birthday, I executed my plan to escape--a supervillain attacked, and I completely exhausted myself, and slept like the dead for three days…during which time the JSPSE buried me. The flooding that night was thought to be completely unrelated; the fact that the cemetery was the worst affected was a tragic and macabre coincidence. The fact that no one thought to check my coffin was a mistake. I made my way out of the wreckage and travelled for seven years under the radar until I reached Austin: a city that averages 300 days of sunshine a year; I've been happier here than I have been for the entirety of my life up until I moved into my apartment.
