Hattori

Hattori (ハットリ, Hattori) is Rob Lucci's pet pigeon.

Appearance
Hattori is always seen wearing a tie, light red while Lucci was undercover as a shipwright and black afterwards. He wore a light green coat identical to his master's while Lucci wore his during the Sea Train ride to Enies Lobby and the meeting at the Tower of Justice.

Personality
Why Hattori's with Lucci is unknown considering the man's reputation as a heartless mass-murderer, though Lucci has had him since he was a child. He apparently isn't afraid of Lucci and is very loyal to him, as he stays close to his master even in dangerous situations like the Buster Call. When Lucci isn't fighting, Hattori is usually perched on his master's right shoulder.

Lucci would have had to express some emotions to blend in with citizens while undercover, but Hattori did this for him as his ventriloquist dummy; this allowed Lucci to be somewhat sociable while remaining emotionless. While Hattori reverts to being an ordinary pigeon after Lucci was revealed to be an assassin, he occasionally exhibits human traits such as drinking from a cup.

History
During Lucci's time at Water 7, Hattori was used as part of a ventriloquism act his master developed; in which Hattori was completely in sync with him, as he was able to move his beak and make gestures with his wings to match everything Lucci says without his master having to do anything.

After the Buster Call, he is seen with the rest of CP9 as they used the Sea Train tracks to escape the pursuing Marines Spandam sent so he could blame the agents for his failed mission. They reached St. Poplar where the agents worked as street performers (Kalifa as a street cleaner) to pay for Lucci's medical fees. He has apparently been following them around the town as he was seen being fed by Kumadori. He was at the window when Lucci awoke, clearly very happy that his master had finally awaken after the epic battle with Luffy. After Lucci was discharged from the hospital, Hattori returned to his perch on his master's shoulder.

CP9 decided to go bowling to celebrate Lucci's recovery, but the game was interrupted when the Candy Pirates invaded St. Poplar. Lucci dealt excessive justice to the captain, for which they had to leave the town. They used the pirate's ship and returned to their homeland where they watched the future generation of CP9 being trained, until Captain Very Good came to capture them. As CP9 fought and defeated the unit, Lucci contacted a crippled Spandam to say that they would be coming for him. They then used Very Good's ship to go after their former director.

Trivia

 * Some cultures don't differentiate between doves and pigeons; "hato" is the Japanese word for both. Should Hattori be considered a dove, then he can be seen as an irony on his master's bloodlust. A dove, especially an all-white one like Hattori, is often used as a symbol of love and peace.
 * In real life, captive pigeons live for about 8-15 years though older specimens have been reported such specimens are rare; most nnotable Hattori was seen with Lucci 22 years ago. He shows no signs of old age, suggesting that pigeons live much longer in the One Piece world than in the real world.
