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 going to use to house the stolen shadow of Luffy.

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

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

History
Five hundred years ago in 1022, Oz died in a frozen land in the Northern Continent. During his lifetime, he built his name by amassing countries and islands under the control of himself and his band of villains. 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. Moria, in chapter 457, puts Luffy's shadow in. Moria grumbles and then screams "meat" and asks for Sanji, following by asking who Sanji is.
