The Son of Peace Master is one of Peace Master's children. He was seen first throwing a shoe at his father in their car. He was next seen being turned into a dragon-monster by Peppermint Butler because Peace Master refuses to comply.
In his normal form, he appears to look similar to Peace Master, with a striped shirt, blue pants, and shoes similar to that of Finn. In his monster form, he grows green scales, yellow wings, a long neck, reptilian eyes, and a dragon tail.
Being a child, he is very fun loving. He seems to be into horseplay and is oblivious to his surroundings, seen being happy to be kidnapped instead of fearful. He was quick to accept his monster form.
- Because he was quick to accept his monster form, we can conclude that he was inserted in the Dark Arts, just like his Sister.
