The origin story of Alastor (Hazbin Hotel fanfic)

Anthony is a chipper young adult who lives with his mother, he likes to go to the picture shows on the weekend and always has a spring in his step. One weekend he gets dressed up to go see a show when he entries the wrong room and see's a stand up comedian instead. He gets inspired and so he starts practicing his routine at home and takes it to the theatre in hope of giving him time on stage. The years go by and suddenly he goes from 23 to 27 in no time. He never found his time in the spotlight until he found the perfect trademark, a permanent smile.
