Captain Marvel Jr. #7

In "The Boy Who Couldn't Grow Up!", Freddy stumbles upon a strange sight—a boy driving a fire engine from the station—and soon finds himself drawn into a mystery when the boy reveals he’s actually a 25-year-old man trapped in a child’s body. After drinking a youth elixir created by his father, the boy now thinks with adult wisdom but behaves like a child, leaving him caught between two worlds.
