Mr. Smee is Captain Hook's first mate. He appears in Kingdom Hearts and Kingdom Hearts Birth by Sleep as an inhabitant of Neverland, and apparently the only other human member of Hook's pirate crew other than Hook himself. He is originally from Disney's Peter Pan.
 Kingdom Hearts Birth by Sleep
Mr. Smee and Captain Hook were transporting a treasure chest full of "light" over to Skull Rock but were attacked by Unversed, until Terra landed onto the world and fought the Unversed. He later appears inside Skull Rock alongside Hook.
Mr. Smee is then seen on Captain Hook's ship attacking Ventus and Peter Pan by firing cannons onto the Island.
Mr. Smee is again, seen on Captain hook's ship attacking Aqua, Peter Pan and the Lost Boys by firing cannons. Later on he is seen with Captain Hook in the Gully with the treasure chest that the Lost Boys and Peter Pan had stolen previously. He - to Captain Hook's orders - opened the chest only to find it was filled with wooden swords, fishing rods and other objects that the Lost Boys and Peter Pan treasure. Then the crocodile swims into the Gully and scares off Captain Hook with Smee following.
 Kingdom Hearts
Smee is seen on the ship 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 affects him is when the party tries to get Captain Hook to come out Peter Pan mocks Smee's voice.
 Kingdom Hearts 358/2 Days
Smee is digging for treasure on the Mainland with Captain Hook when Roxas first arrives in Neverland. When they came across an empty box where they assumed a treasure would be hidden on one of their many recently collected treasure maps, Smee was very surprised when the pirate's darkness summoned Heartless. He and the Captain ran back to their ship and left a currently unseen Roxas to deal with the dark creatures, Smee later seen as Tinker Bell flew above Hook's ship as the pirate commanded his first mate to plot course to the next treasure location. Smee would continue to aid the Captain in his endless quest for gold, half-heartedly summoning Heartless as he worked.
Smee is a short, rotund man with an odd, hourglass-shaped head. He has shoulder-length, white hair (though the top of his head is bald) and thick, black eyebrows. His eyes are black and close-set, and they are often half-closed. His nose is large and pink, and the rest of his skin is slightly pink as well. In terms of clothing, Smee wears what seem to be very simple, brown sandals, a short-sleeved shirt with alternating sky blue and white horizontal stripes, and teal shorts. He also wears half-moon spectacles and a floppy, conical, red hat with a red puffball on the tip.
Smee is a weak character, often seen being rushed around by his captain. Even though his captain gives him a lot of trouble, he is very loyal to him. He is clumsy, goofy, and unlike his captain, he's very kind. Smee is also very timid, submitting to anything that poses any sort of threat.
He first originated in J. M. Barrie's Peter Pan series novel, Peter and Wendy, in 1911. In the novel, he is one of the two pirates who survived from Peter Pan's massacre.
In terms of Peter Pan, Smee acted as Hook's right hand man, like he does in the game. Often, Smee is the one who rows the boat for Hook and is the one that Hook cries for when the Crocodile is around. Smee is the one who swipes Tinker Bell when she watches Peter Pan and Wendy disdainfully and writes down the location of Peter Pan's hideout when Hook tricks her. In the end, Smee is left in a lifeboat and goes after Hook, who is sent skipping across the water after being defeated by the crocodile.
Smee appears in the sequel, Return to Never Land, where he helps Hook capture Jane, Wendy's daughter, and take her to Neverland as part of a trap for Peter Pan. At the end of the film, the Jolly Roger is sunk, and Hook, Smee, and the other pirates are chased away by an octopus, who mistakes them all as codfish.
