(Male Presenting, 20s to play kid) Frankie (age 11) is a boy genius. He is dealing with the death of his father. He’s a nice kid who gets super excited about science. He’s like one of the kids in “Stranger Things.” Baritenor

(Female Presenting, 20s to play kid) Sarabeth (age 11) is gifted and talented but not stuck up in anyway. She really “likes” Frankie. This and the fact that her parents are splitting up are forefront in her life. Soprano with strong mix

Mom is youngish (late 30s). She is trying to cope with the loss of her husband and is very worried about Frankie. She is real and caring, but has an over the top hysteria. Audrey (age 11) is one of those smart, nerdy kids totally focused on preparing for a successful life. Her mom has her overscheduled for lessons and activities. She’s blunt, often at the wrong times. Alto/Mezzo

Polimorfus is professorial and serious. The Monster is, in the first part of the show, sweet, gentle, innocent and a little glam-tastic. Later on, when he becomes evil, he’s streetwise, sarcastic and menacing. Should be tall! Baritenor

(Male Presenting, 20s to play kid) Louis (age 11) is self-centered and very full of himself. He’s shifty and sneaky and, ultimately, a coward. Tenor.
