The crew's Jolly Roger is a white skull with two purple wings, and a white flame on each side of the skull.

In spite of this, the crew counted on three members who had eaten Devil Fruits; and they were able to fight the Straw Hat Pirates, steal the shadows from some and almost finish them off with Oars, which they could only avoid by facing the giant as a team.
- Further information: 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 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 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.
Little is known about the crew's past. Gecko Moria formed a crew reuniting to Absalom, Perona, and Hogback, that began to be called the "Mysterious Four", and in the West Blue, transformed the island Thriller Bark in a ship.
Thriller Bark Arc
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 Timeskip
Absalom became a popular journalist under the nickname "Absa".
Wano Country Arc
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.
