This was retconned for the 2023 reboot film Peter Pan & Wendy where the Lost Boys (still named as such) now include girls.

By the end of the novel, Prentiss, James, Tubby Ted, and Thomas decide to go back to London with Leonard Aster because they realize they would become men some day and cannot keep up with Peter forever.

In Peter Pan in Scarlet, Tootles becomes a girl because he only has daughters to borrow clothes from in order to become a child again and go back to Neverland.

Nibs is the only Lost Boy not to return to Neverland because he can't bear the thought of leaving his children.

Slightly grows up to marry a noblewoman and becomes a lord, though he has become a widower at the age of thirty and is the only one of the Lost Boys not to father any children.

In Barrie's original works, the Lost Boys leave Neverland and grow up, while in the Disney films they are merely tempted to, but change their minds and choose to remain with Peter Pan.

Cubby and Slightly appear alongside Peter Pan and Tinker Bell in Kingdom Hearts Birth by Sleep.

Cubby made a minor appearance in Kinect Disneyland Adventures as he was kidnapped by captain hook, and forced to reveal Peter Pan's hideout.

Alongside Tiger Lily, they meet Wendy after she was separated from her brothers and Peter Pan following a cannonball attack from Captain Hook's ship.

In Spielberg's sequel Hook (1991), there are at least two dozen Lost Boys of various ethnicity living in Neverland, whose clothes suggest that they left various civilisations at different times over the past century.

However, Tinker Bell and the glimpse of Peter Pan that Pockets sees in Banning's face convince them and they train him for a showdown with Captain Hook.

The Lost Boys gradually come to believe in Peter, a turning point being when he manages to beat Rufio in a heated name-calling match.

The Lost Boys follow Peter into a climactic battle with Captain Hook and the pirates, armed with improvised childlike weapons.

Peter's son Jack, witnessing Rufio's death at the hands of Hook, turns away from the life of a pirate and reconciles with his father.

Later in Neverland, Thud Butt gives Peter a small bag containing Tootles' marbles, revealing that they were his happy thoughts and he lost them literally rather than metaphorically.
