Oars

Oz (オーズ, Oozu) is the 900th Zombie creation of Hogback. He was a giantic beast that used to roam and wreck havoc around the the world. He is the Zombie that Gecko Moria is using to house the stolen shadow of Luffy.

Appearance
He is very large, with hair like a lion's mane, except much longer. He has long horns, sharp fangs, including two tusks and no nose. He has large arm shaped like Franky's arm with a "900" tattoo on his left arm. Like other zombies, he is stitched up.

His Zombie Number is prefixed by an "SZ", presumably for "Special Zombie".

His sheer size has been commented by several people to be bigger than a regular giant.

Personality
It's not exactly known what Oz was exactly like in life however it is suggested that was a ferocious beast. Since being fused with Luffy's shadow, Oz inherited several of Luffy's character traits. This includes Luffy's desire to become the Pirate King. It's not currently known if this would affect his overall loyalty to Gecko Moria.

Abilities and Powers
Oz is an extremely strong beast by himself. With Luffy's shadow animating him, he has become even more powerful. While he is capable of performing Luffy's signature moves, he however alone cannot stretch his limbs like Luffy does with the aid of his Devil Fruit powers. He however is somehow able to do so with the aid of Gecko Moria.

While most of his attacks are based on Luffy's, Oz surprisingly however has personally created a move of his own. Called Gomu Gomu no Shirimochi, Oz uses his large buttocks to stomp on his opponents by jumping upon them. This move doesn't exist in Luffy's inventory of Devil Fruit based moves.

History
During his lifetime, he built his name by amassing countries and islands under his control and his band of villains. Five hundred years ago in 1022 AOS, Oz died in a frozen land in the Northern Continent. Chopper later theorized that the cause of death was exposure or frostbite as after examining him he found the giant had been unprepared (he was wearing just a loin clothe) for the frozen climate. On top of this Oz had sustained a serious injury to his right arm (which Hogback had repair).

Gecko Moria then found his corpse and with the help of Hogback's surgical skills stitched his body back up. Oz was then kept in a giant freezer until a suitable shadow was found. With Luffy's shadow, Moria awakens the behemoth. Upon awakening, Oz grumbles and then screams "meat" and asks for Sanji, following by Oz himself asking who Sanji is.

To appease his appetite, a large quantity of food was brought to Oz by Moria's zombies. The amount nearly depleted all of Thriller Bark's reserves. After a brief conversation with Moria, Oz then punched a way out of the freezer. He then climbed up the main mast and scouted out the entire island of Thriller Bark. He then jumped down and accidentally destroyed the large stairway leading to the main mast. He then fell down to the area below.

Despite Zoro, Sanji, Franky and Usopp being near him, Oz simply ignored them and picked a large piece of debris which he put on his head like a tricone. He then continued exploring the island. Oz then found the giant chain that steered Thriller Bark. Curious on what it does, Oz decided to pull on it. His actions for doing so caused the whole island to move and drift to a different sea current. Angered by Oz's actions, Absalom sent the Zombie Generals after him. Oz merely jumped out of their way and pummeled them into oblivion.

Oz was then later called by Gecko Moria. Now completely obedient, he received the order to rampage through Thriller Bark, capture the Straw Hats, beat them, and put them on their ship. With the Straw Hats' wanted posters posted on his arm, Oz then started attacking Luffy and began rampaging through the main mast tower, searching for his targets. Along the way, Oz seemingly crushed Hogback and Cindry under his feet. After going through the tower, Oz came out to a courtyard and cried out at the Straw Hats to "come out".

Finding the crew ready to face him, minus Nami and their Captain, he begins a massive battle. The Straw Hats' first attacks barely faze him, and he knocks them all down with a single attack. When they rejoin the battle, they score several significant hits on the monster, but the result is a stalemate. Gecko Moria, deciding to deal with the pirates quickly, then enter's Oz's stomach using his shadow powers, piloting Oz like a giant robot. By manipulating Oz's shadow, Moria allows his giant servant to stretch like Luffy, and increase his strength. One by one wthe crew members are put out of action- Franky, Brooke, Robin, Sanji, Chopper- until only Zoro, Usopp and the newly arrived Nami remain.

As Zoro gives Usopp a opening to launch Brook's bag of salt at the monstrosity, Moria quickly save Oz by letting his own shadow throw out the bag of salt. But, before Usopp and Nami are destroyed by Oz, Luffy (in his Nightmare form) comes to the rescue. As Oz tries to obliterate Luffy with a Gomu Gomu no Rifle, Luffy stops it with only one arm, stating that there can only be one Luffy. Then, Luffy proceeds to pummel Oz good, destroying what is left of the courtyard. Then, after showing his massive powers, Luffy seemingly finishes off both Oz and Moria with a sideways Gomu Gomu no Storm.
