Peter Pan's shadow is the living shadow of Peter Pan
In the film, while Peter was visiting the Darling household to listen to stories, the Darling's dog Nana barked at the intruders and while Peter escaped, his shadow was captured. That night, Wendy Darling discovered the shadow and stored it in her draw to prevent it from getting into trouble. The next night, Peter and Tinker Bell returned to retrieve it. When they found it, they accidentally woke Wendy. As Peter attempted to restore it with soap, Wendy preferred the proper way, and sewed it back.
Peter Pan's shadow is first shown when Peter Pan send your avatar on a mission to find it. It is like a meet-and-greet character except you must copy his movements and find it three times throughout Disneyland.
In this show, Wendy Darling meets an entity she refers to as the Shadow outside her nursery window, and gets up to to take her to Neverland. Her friend Baelfire is wary of it, and makes her promise to keep away from it. However, the Shadow returns and takes Wendy with it. She returns in the morning, but reveals that the Shadow now wants one of her brothers, John and Michael to take back with it. To make sure it doesn't succeed, Wendy, Baelfire, John and Michael hide in the cubby-hole the next night when the Shadow comes back. However, Michael gets distracted by the Shadow, forcing Baelfire to dash out and protect Michael by asking the Shadow to take him instead. Despite Wendy's pleas, Baelfire knows this is the only way to keep the Shadow from making off with one of her brothers. She, John and Michael watch as Baelfire is pulled up and disappears.
The Shadow takes Baelfire towards Neverland, but Baelfire lights a match to ward off the Shadow, causing it to drop him into the sea, and after searching for a brief moment, it cannot find Baelfire and flies back to Neverland.
It is revealed that this shadow belongs to Peter Pan, and it brings children to Neverland to keep them there as ordered by its master.
The Shadow appears many years later aiding the Lost Boys in acquiring Henry Mills from the rogue Greg and Tamara. It assists in the attack by stealing Greg's shadow, leaving him in a comatose state, and flies off with its captive.
Peter's shadow can be seen flying through the walls in the popular dark ride attraction Peter Pan's Flight. The shadow plays a significant role in Disneyland Paris' nighttime show Disney Dreams!. Here, the shadow unleashes some of the magic from The Second Star to the Right. As the shadow enjoys himself with some of the Disney characters, he is attacked by Captain Hook and his Disney Villain allies. Peter and Tinker Bell arrive and successfully restores the magic, defeating Hook.
