When I was young, my father left my mother, brother and I. We fell into poverty and lived on the streets for years. After I had experienced enough of watching the rest of my family suffer, I took action into my own hooves. I began to take from those who were filled with greed, and gave it to those who needed it most, my family.
Unfortunately, it wasn't enough to help them though, as my brother was taken away and my Mom was infected by a fatal virus. I was all alone. I didn't know what else to do afterwards, other than what I had been doing, stealing. I continued to take for most of my years. I had done it since I was a colt, so I became more and more efficient. I even gained a bit of reputation.
But one day, on a special theft operation, I was exposed to some unspeakable magic that granted me powers of telepathy and telekinesis. When I was able to harness these abilities, I strove for a much bigger target than petty theft. I wanted revenge, not only from my father, but Equestria for having taken the ones I loved.
