Tinker Bell is the little fairy who lives in Neverland alongside her best-friend, Peter Pan and has appeared in Kingdom Hearts, Kingdom Hearts: Chain of Memories, Kingdom Hearts II, Kingdom Hearts 358/2 Days, and Kingdom Hearts Birth by Sleep. She is originally from Disney's Peter Pan.Tinker Bell is introduced to Sora, Donald, and Goofy when they meet Peter Pan in the hold of Captain Hook's galleon. Tinker Bell informs Peter that she has located Wendy (she, however, has a deep jealousy for Wendy, due to her growing relationship with Peter). Tinker Bell later sprinkles the trio with her pixie dust for later use of flight. Peter rescues Wendy and flies off somewhere, leaving Tinker Bell and the others to fight for themselves.

Tinker Bell is then captured by Hook and held hostage in a lantern - her life or the Keyblade is Hook's demand. Sora walks the plank instead and flies thanks to happy thoughts. Peter returns and saves Tinker Bell from Smee. After Captain Hook takes the plunge and is defeated, Tinker Bell reappears and tells Peter of something happening at the clock tower in London. They go to the clock tower (Big Ben) in London where Sora seals the Keyhole. Tinker Bell seems to approve of Peter and Wendy's friendship at last and Peter asks Sora to take Tinker Bell with him as an ally. Tinker Bell is delighted to go with Sora as a summon.

If one returns to Neverland, Tinker Bell tells Sora and Peter of the Phantom Heartless at the clock tower.
