 * General Zombie: Once legendary figures, now commanders of the rest of the zombies. They are under the command of Absalom.
 * Surprise Zombie: Zombies that disguise themselves as everyday objects to scare the enemies.
 * Soldier Zombie: Common grunt zombies for combat.
 * Wild Zombie: Wild animal zombies with high level strength. They are under the command of Perona.
 * Special Zombie: A unique kind of zombie that is stronger than General Zombies. Oars was the only one of its kind.

Thriller Bark
Thriller Bark was the ship that gave name to the Thriller Bark Pirates. It was an island that was transformed into a ship by Moria, and served as a ship for the crew until they defeat against the Straw Hat Pirates, although it seems to be later reclaimed by Moria who used it to travel to Pirate Island.

Escapee Ship
After Gecko Moria’s defeat, Hogback and Absalom were seen escaping from Thriller Bark (along with the still unconscious shichibukai) in a smaller ship with black sails and a bat figurehead.

At the beginning of the Dressrosa Arc, the ship was seen leaving the Kid Pirates’ base carrying two people.

Flash Barrel
A Flash Barrel is a barrel that contains the red flare inside used to signal Thriller Bark. It floats on the ocean at the entrance of the Florian Triangle, waiting for any passing ships. Whenever opened it will shoot out a red flare after which Perona's Ghost Network will start spying on them. This was a clever trick to pull sailors to Thriller Bark.

Purified Sea Salt
Purified Sea Salt is simply salt extracted from the sea, and purified. However, they play a crucial role in defeating the zombies on Thriller Bark. Since salt is an extract from the sea, it can be used to cancel the Kage Kage no Mi's shadow-extracting powers, and purify the zombies, rendering them a husk once again. The amount of salt needed to feed a zombie is proportional to its size, as Oars was immune to a small pellet of salt shot into his mouth.
