Bitten by a radioactive man, Alexander von Koopa is the last son of his dying planet, Alexander von Koopa. He was also the only resident. Don't judge. Then one day some guy threw acid into the face of his parents in an alleyway, and a particle accelerator blew up. Thus Alexander von Koopa gained the power to reference a lot of things. And play video games sometimes.
Along with writing, he also does voice acting, and is directing Undertale: The Musical for Man on the Internet Productions. No, he's not ashamed of shameless self promotion, why do you ask? Don't tell him what to write, he's the one at the keyboard!
