Transcended Pirates

Heavenly Bodies
The Heavenly Bodies are Milky's First Mates, where three people hold this position, each having their own specific jobs and duties. Their power and command over the crew are second only to Milky. It is stated by the lower ranking crew members that together, they have the power to come close to rivaling that of a Yonko, being referred to as monsters from the underworld than actual beings. While Milky does respect their power, refusing to intervene if they ask him to not, if Milky finds that the damages inflicted them are severe, Milky will go on a rampage to avenge his fallen brother(s). It is also stated by the lower ranking crew members that those within the Heavenly Bodies are the true commanders of the pirate crew, as well as the Imperial Government. However, this rumor is false, as Milky takes his Captain duties seriously. To add onto this, Steorra, Sunne and Maenon were able to keep the Transcended Pirates, as well as the Imperial Government, in-tact until Milky's return, showing great leadership skills, as well as strategic expertise, from their parts.
 * Steorra manages the Hajika, where his choices in who is kept and taken out are final unless Milky decides to veto his decisions. Despite having near complete authority over the Hajika, not all members willingly follow all of Steorra's orders. An example of this is Jongin Yi Nisaban, who, on several occasions, has refused orders from Steorra, which has ended up with the former becoming reprimanded by either Steorra or Milky himself.
 * Sunne acts as Milky's advisor. While this is jokingly stated, Sunne deems his position to be more of a babysitting job. While Milky is competent, he does act reckless at times, which requires Sunne to intervene on certain matters so that relations are still kept. He is primarily the one seen with Milky the most, often accompanying him on Milky's voyages.
 * Maenon manages the Animan, Human and Animal Divisions, keeping track of all the members and provide missions for them. While the crew is completely willing to allow members to join their ranks, there have been a few occasions where people have been rejected, mostly due to Maenon doing it himself.

Hajika
The Hajika are the Transcended Pirates' last line of defense before the Heavenly Bodies. Their ultimate purpose is to counter the World Government's Shichibukai. Just like the Shichibukai, they act separately from one another, acting more like minor divisions than a group. While they are normally left to their own accord, they are summoned at times of war, or in times of when a meeting is required to discuss the situation of the Imperial Government as well as worldly affairs. There have been occasions here the Hajika are not treated with the respect they deserve, mostly to members such as Jongin Yi Nisaban, causing discrepancies in who they take orders from. Despite this, all members seem very willing to serve Milky and the Transcended Pirate's goals. Most members own territory that is put under the protection of the Transcended Pirates, making them that much safer due to being under the protection of a Yonko crew. The balance of power between the Hajika vary, as some members are far stronger than the others and vice versa. This makes some members capable of fighting on par with Shichibukai members, while others cannot handle fighting a Shichibukai alone. Together, however, they are able to equally fight on par with the Shichibukai if both groups were to fight against one another.

The Three Divisions
Aside from the Heavenly Bodies and the Hajika, the crew is made up of lower-ranking members that do not fit into any other category. They are categorized depending on Milky's philosophy on evolution, where animals are sent to the Animal Division, humans within the Human Division and sentient beings, that are not humans, within the Animan Division. The power scaling between the three groups also follow this logic, where those within the Animal Division are generally the weakest and the Animan Division being the strongest. Those within any division can be recruited by members of the Hajika for their own needs, but it needs to be ran by Maenon. The Three Divisions hold no special authorities, where one division has no power over the other, and are considered the crew's footsoldiers.

Neptune
Neptune (ネプチューン Nepuchūn) is the main ship of the Transcended Pirates, only used in times of war, or in special missions. Instead of being a normal ship, he is instead an enormous whale coated in a rocky coating to protect him from attacks. Neptune, due to being a sentient being, is more than capable of combating against other things within the ocean, whether it's a ship, or an animal. His power is capable of rivaling Sea Kings, protecting the people within him from their attacks. His insides have been modified to allow for people to be inside of him, allowing for a comfortable voyage. The holes on his coating store cannons for cannon fire when in times of trying to hit a further-distanced enemy. He is normally found around the area between Fishman Island and the Transcended Pirates' main island.

Venus
Venus is Milky's main mode of transportation between the Grand Line and the seas. Despite Milky being able to fly with ease, he prefers to travel around via his ship. While Venus is not a modified ship like the other ships of the Transcended Pirates, Milky considers her as a ship. She is easily capable of carrying several people without slowing down in speed. Venus has also been shown to have some combat capabilities, as she is able to sink ships with effort.

Saturn
Saturn is Steorra's main mode of transportation between the Grand Line and the seas. Saturn is a modified ship, capable of housing several people within his shell. While Steorra does use this ship for transportation purposes, it has been shown to be used for other purposes. Within the center of Saturn's shell lies a meeting room with several shells stacked with books. Steorra has occasionally held meetings within Saturn, as well as planning for wars. Saturn is considered to be the most durable between all the ships, only being inferior to Neptune's coating.

Mars
Mars is Sunne's main mode of transportation between the Grand Line and the seas. Mars is a modified ship, being the only one with a heightened sense, capable of sensing incoming danger. However, Sunne claims that this was not a modification and it's a natural ability of Mars. Mars is capable of housing people within its shell, and is capable of carrying thousands of people without any hindrances. In times of war, Mars is used to transport troops onto the battlefield with Neptune.

Uranus
Uranus is Maenon's main mode of transportation between the Grand Line and the seas. Uranus is a modified ship, but is much weaker than the other ships. To make up for this, Uranus is capable of hiding his presence without any sort of detection from outside forces, almost as though he blends in with his atmosphere. Even users trained in Kenbunshoku have claimed that this ship is bothersome to find. While it is large in size, Uranus can only carry a handful of people without slowing down, making him more of an escape ship than anything else.

Explorer Fish
Explorer Fish is a modified ship that only holds the purpose of searching the seas. Due to its modifications, it is able to house one person, the pilot. It houses ranged artillery in case of incoming enemy attacks. Explorer Fishes are kept in high amounts for the Transcended Pirates, and each one has a Den Den Mushi to communicate with others.

Sinker Fish
Sinker Fish is a modified ship that swims around the Transcended Pirates' main island to attack unauthorized personnel. They are able to operate on their own, not needing a pilot to steer them. They have several cannons and ranged weapons to do their tasks.

Transport Walrus
Transport Walrus is a modified ship that stays true to its name, where its only purpose is to transport people from place to place. They are normally sent out when the members of the Hajika are called upon to convene for a meeting.

Trivia

 * The Transcended Pirates have two apparent themes. The first being a Space theme, where several of the members are named after things found within space, including the ships. The second theme is animals, where several members either are animals, or have Zoan Devil Fruits.
 * Both of these themes coincide with Milky's evolution philosophy.
