Tinkerbell
Sora meet Tinkerbell when he, Donald and Goofy were captured by pirate ship. Tinkerbell found the three heros and took a liking to Sora, and a disliking to Donald. She lead them to Peter Pan, where they all made a pact to save their friends and escape the ship. While traveling through the ship, Sora wondered how they flew. Tink sprinkled some pixie dust on them, which helped them out much later. When they finally escaped, Tink grew attached to Sora. Peter asked if he'd be willing to take her along. You can obtain the Tinkerbell summon in Neverland. When summoned, Tinkerbell appears and heals Sora for a period of time.
