Smee

Mr. Smee is Captain Hook's first mate. He appears in Kingdom Hearts as an inhabitant of Neverland, and the only other human member of Hook's pirate crew other than Hook himself; the rest of the crew consist of Heartless.

Kingdom Hearts
''Hook's first mate. He lives to take orders from Hook, but he's as slow-witted as Hook is obnoxious.''

He appeared in "Peter Pan" (1953).

Kingdom Hearts Birth by Sleep
Recent Famitsu scans show Mr. Smee and Captain Hook guarding a treasure chest and nervously cowers as a group of Unversed confront him and an angry Captain Hook.

Kingdom Hearts
Smee is seen with Captain Hook in Neverland, Smee appears to be Captain Hook's right hand man and also his only human companion. Smee assists his captain in the capture of Peter Pan and trying to make Sora and company walk the plank. The last factor that effects him is when the party tries to get Captain Hook to come out Peter Pan mocks Smee's voice. This shows that obviously Captain Hook has a lot of trust in Smee.

Kingdom Hearts 358/2 Days
Smee reappears alongside his captain on the mainland of Neverland.

Trivia
Monsieur Mouche
 * Smee doesn't seem to hate Peter Pan as much as Captain Hook.
 * Looking at the movie and his role in the game one can speculate that Smee is not a villain but simply very loyal to Captain Hook. Keeping in tune with the Peter Pan books, Smee's past with the captain might effect why he's willing to go with Captain Hook on any plan.
