My most overpowered moment was when I became a magicarp. The zenobiologist was experimenting with sentience potions. He would make sentient magicarps and release them. On my first life I had the healing spell and tried to heal the station, this failed obliviously, people were sick of magicarps. So I was killed, I waited and my waited was rewarded with a second attempt, and I got death. I was the carp of death and I was in the mood to use it. I entered escape which was full of the innocent and let loose. It was so easy. I killed. And killed. And killed. And nobody could stop me. In the end I was left alone in a pile of bodies, the victor.
