Tinkerbell or Tinker Bell (the author's spelling of the name) is a fictional character in J.M. Barrie's play and subsequent novel Peter Pan. She is a sometimes ill-behaved and vindictive, but loyal fairy who is Peter Pan's companion. In one famous scene, Tinker Bell will not die if enough people believe in fairies. The resultant plea to the children watching the play or movie is an example of "breaking the fourth wall"; in the novel and the 2003 movie, Peter calls out to dreaming children within the storytelling universe to sustain her. In the end of the novelization, when Peter returns to Wendy after a year, it is revealed that Tinker Bell "is no more" since "fairies don't live long, but they are so little that a short time seems a good while to them." Like nearly everything that has happened in the story, Peter has forgotten her—real death and sadness cannot exist in his everlasting childhood.
