Morgan

Captain Morgan (モーガン大佐 Mōgan Taisa), called "Axe-Hand Morgan" (斧手のモーガン Onote no Mōgan) since he literally has an axe for a right arm, is the first Marine officer of significant rank to be seen in the series.

Personality
When Morgan is first introduced, he is governing over the small island of Shell Town, where his Naval base is located. Yet he is ruling by fear, abusing his rank to make people pay taxes, and even going as far as killing his own men if they do not obey his commands. He has a very spoiled son named Helmeppo, who is just as bad at using his father's rank to get what he wants from the island's inhabitants.

Past story
It is revealed in the Captain Kuro Arc that he was the only survivor in an attack by Kuro on a Marine ship, which left him with a broken jaw. He was hypnotised by Jango into believing that he had captured Kuro (actually a lookalike pirate), gaining him immediate fame and possibly setting him on the path to his current obsession with rank and power.

Present story
He was left in charge of a Marine base on an island. As a high ranking and famous Marine, none dared challenge his authority, not even his own men as he had a habit of punishing those who disobeyed him (even killing his own men).

This all changes however when Luffy comes to town to help Coby fulfill his dream, and possibly recruit Roronoa Zoro into his crew. After Luffy accidentally breaks a newly finished statue of Morgan, the captain immediately sets after him, confronting Luffy in the courtyard of the Marine base. Morgan is defeated by Luffy without even landing a single blow, though he is finished off by Zoro as Luffy has to deal with Helmeppo holding Coby hostage.

Current Story
Morgan was later seen in the series was in a chapter title page mini-story, as a prisoner stripped of rank on Vice-Admiral Garp's ship, where both Coby and Helmeppo also happen to be serving. However, he slashes Garp and escapes the ship by using his own son as a hostage. Helmeppo disowns him shortly thereafter and returns to the Marine ship, leaving Morgan alone and drifting the ocean.

He was seen again as a cameo in Jango's Mini-arc taking a nap in the ocean as Jango unknowingly passes him.

Major Battles

 * Vs. Kuro
 * Vs. Luffy (with the help of Zoro)
 * Vs. Helmeppo and Koby

Early One Piece
Helmeppo was drawn before his father and early drawings of Morgan greatly resembled Helmeppo's own appearance. One example had him almost identical to Helmeppo, with just a crazier hairstyle. He was given his final design after the editor told Oda he looked lame.

Morgan's original name was going to be 'Captain Chop'. Oda explained that he didn't have the nerve to actually use this name. (His name also apparently was similar to a wrestling move by a famous Japanese wrestler called Giant Baba).

Cultural References

Trivia

 * The word "Möwe", which appears on Morgan's metal jaw, is German for "seagull."
 * Oda admitted that Morgan was based on a real-life pirate, most likely Henry Morgan, who also began his career as a law-abiding seafarer.
