Like other characters in the Little Nightmares series, the Runaway Kid does not speak, but his personality is shown through his actions. It is presumed that he puts it in his pocket when not in use. He possessed no objects until finding a flashlight, which he used repeatedly throughout his adventure. His feet and hands are bare, like most children.
He has short charcoal brown hair with long bangs that completely cover his eyes, only revealing a tiny mouth and nose. He also has a metal cuff with a broken chain wrapped around his right ankle. He wears a blue garment, with a collar around his neck and long slate blue pants.
The Runaway Kid was around the size of Six, with a similar lean build, both being scrawny and thin.
