The majority of the Thriller Bark Pirates are an undead army of seemingly-invincible zombies, powered by the shadows stolen using Moria's Devil Fruit. At the time of their introduction, the Thriller Bark Pirates had amassed a crew of nearly 900 zombies animated from the dead, including the likes of deceased legendary figures such as Ryuuma, Captain John, and the ancient giant Oars. The undead crew relies solely on the authority of their captain and his three lieutenants which makes up the "Mysterious Four", three of whom being Devil Fruit users while the other possesses the medical knowledge to create the zombies that made up their crew.
The Thriller Bark Pirates were known for their Night Attacks (夜討ち Yōchi?) that takes place every midnight, to which the zombies would attack and capture every victim that has been trapped on their island. Those taken captive are then brought before Moria, who proceeds to steal their shadows with his Devil Fruit before sending them back out to sea. They were shown able to fight and catch the Straw Hat Pirates by surprise, steal the shadows from their strongest members, and almost finish them off with Oars, which the Straw Hats had to fight as a team.
Their captain Moria was even recognized as a member of the Shichibukai, giving them special privileges and officially sanctioned by the World Government. However, after suffering a crushing defeat from the Straw Hat Pirates that costed them their undead army, Moria would be expelled from said group for "being too weak", in Doflamingo's words.
- Further information: Thriller Bark
Thriller Bark was the ship and namesake of the aforementioned crew. It was an island that was transformed into a ship by Moria, and served as a ship for the crew until their defeat at the hands of the Straw Hat Pirates. It was abandoned for two years, but appears to have been reclaimed by Moria who used it to travel to Pirate Island.
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.
In Hogback's flashback, a ship with a normal style that seems to be used previously by the crew is seen.
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 SaltEdit
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.
After Gecko Moria lost his previous crew, the Gecko Pirates, to Kaido, his perception of comradeship was forever shattered. He then formed a new crew, the Thriller Bark Pirates, in which he recruited included Absalom, Perona and Hogback, the four being known as the "Mysterious Four". They utilized the island Thriller Bark and transformed it into the largest ship in the world. Moria's trauma led him to create an army of undead zombies as the main force of his new Thriller Bark Pirates, in which he held no sentiment towards due to losing his crew of live members.
Thriller Bark ArcEdit
After the Straw Hat Pirates arrived at Thriller Bark, Moria stole the shadows of several of the members, and gave life to Oars thanks to Luffy's shadow. Later,Bartholomew Kuma arrived to inform Moria about the upcoming war against the Whitebeard Pirates, prompting Moria to set sail. As the Straw Hats fought three of the Mysterious Four, Kuma used his Nikyu Nikyu no Mi abilities to send Perona to Kuraigana Island. After Oars and Moria were defeated by the Straw Hats and Brook, Hogback and Absalom took an unconscious Moria to Marineford.
After the war Moria ended up being expelled from the Shichibukai.
During the TimeskipEdit
Absalom became a popular journalist under the nickname "Absa".
Wano Country ArcEdit
After discovering news about Moria and his new army of zombies in the newspaper, Perona went on his search. In Hachinosu, Moria was looking for Teach, and when he met the Blackbeard Pirates, he discovered that Absalom was killed by them, his ability taken by Shiryu.
