Sailor Moon is a unique world of superheroes and supervillains who commonly use planet names and gemstones depending on their status. In order to play we do not usually require previous knowledge of the series as this guide contains most of what you need to know about our powered characters.

It is, however, usually recommended to play a human with no powers if you're unfamiliar to become comfortable with the setting.

Power Types

In the Sailor Moon universe, every being (plants, animals, humans, etc.) begins with a Star Seed, and that Star Seed travels from the Galaxy Cauldron to their new host. Star Seeds have the potential for infinite growth, and it all depends on the person and their own potential.

It is the planet that chooses its Guardian at the time of their birth. While some Guardians may have inherited their role, it is entirely possible for a Guardian or Knight to have been chosen by chance.

At Eternal, we have named the variety of different types of Star Seeds beyond the standard ones in the Sailor Moon universe. We also believe that while a Sailor Crystal may be among the strongest of all the Star Seeds, power levels do vary – it all depends on the potential of the Seed itself.

For example, someone who was blessed by Chaos may be capable of combating a Sailor Guardian and match them, just as a Knight may be able to match a Sailor Guardian in power. Do not assume that a character is not powerful simply because they are still in their Eternal stage or are designed to match the Eternal stage, as a lot of it crumbles down to their experiences and other criteria on just how powerful they are.

Sailor Guardians

A Sailor Guardian ("Sailor Senshi") is a warrior who possesses the Sailor Crystal of their respective planet. A Sailor Crystal is among the strongest sources of power as they were given the power of their planet. Sailor Guardians are considered "royalty" of their planet and are destined to rule it.

They are differentiated by the sailor collar that they wear which often has stripes on it. However, their sailor fuku (outfit) does not always consist of a sailor uniform--only the collar is retained. A Sailor Guardian must be of female sex, though they may identify as non-binary.

Sailor Guardians use certain phrases to trigger their form, e.g. a Solar Guardian may transform with "Mars Eternal, Make Up!" whereas a Kinmoku Sailor may transform with "Kakyuu Planet Power, Make Up!"

Unlike other tier types, Sailor Guardians also have a unique ability to gain new power stages. For example, Sailor Mars originally transformed with "Mars Planet Power, Make Up!" and moved to "Mars Crystal Power, Make Up!" and had stages such as Sailor Mars, Super Sailor Mars, and Eternal Sailor Mars.

Chaos Seed Blessed

Those blessed by Chaos have their Star Seed corrupted and transformed to suit Chaos’s whim. In the case of Queen Metaria, she petrifies the Star Seed and it turns to stone, whereas in the cases of other Chaos agents it may vary based on their agenda.

A person with a blessed Chaos Seed has been given power, but unlike a Sailor Guardian, Knight or Advisor, they are subject to Chaos’s whim. Chaos can, at will, take their blessed Chaos Seed away from them and kill them at any given time – their power is never permanent – and it is through Chaos that is the only method of obtaining power unnaturally.

Their power levels may vary drastically based on their loyalty to Chaos and how much Chaos may favor them. No case is ever the same.


Knights are unique to the game even though the original "knight" was Tuxedo Mask. Tuxedo Mask is one of the few knights who possess their own Sailor Crystal as he is the Guardian of Earth.

Unlike a Sailor Guardian, Tuxedo Mask has his own uniform (a tuxedo with a cape) to hide his identity. He is considered the king of the planet Earth due to his Sailor Crystal, the Golden Crystal.

Other knights in the game do not operate like Tuxedo Mask as they do not have a Sailor Crystal. Instead, knights have a "Knight Gem" which they receive their powers from, and their uniform is unique to the system they're from.

Their Knight Gem is affiliated with their planet's power, but they are not nearly as powerful as a Sailor Guardian. A knight is usually destined to protect their planetary Sailor Guardian, and most knights will have a name such as "Mercury Knight."

Knights are usually not royalty to their planet unless they are related to the Sailor Guardian. Knights can will themselves into their form, or transform with "Venus Knight Power!" if they choose.


Advisors are Advisor Seed holders who obtained the blessings of the Sailor Guardian or ruler that they advise. When an advisor has received a blessing from a Sailor Guardian, it is usually done through ceremony, and the customs vary per planet and Guardian. With the blessing of their charge, their Star Seed merged with their charge’s and evolved into a dual-planetary seed.

For example, Luna, Artemis, and Diana are from the planet Mau, and while they were born with a Mautian Star Seed, they obtained the blessings of the Lunarian royal family and their Star Seed evolved into Lunarian Seeds. The same is especially true for Phobos and Deimos, who originate from the planet Coronis and obtained Martian Seeds after they were blessed by Sailor Mars.

With the blessing that they’ve obtained from their charge, Advisors can guide them and making them stronger. They have formed a spiritual bond which allows them to ‘sense’ when their charge is in danger or has died.

Be aware that Advisors are uncommon, as they must have obtained the blessings of the planet’s ruler in order to have their Star Seed evolve.


Superhumans are humans with powers and are usually the weakest power type as they always have a True Star Seed.

Be aware that normal humans do not normally become superhumans. Earthlings will never have powers that weren't obtained through some alliance from a criminal faction. Superhumans are "corrupted" humans by Chaos as he gave them powers.

The Dark Kingdom gives humans "stones" that contain their power, e.g. a Dark Kingdom clan member could be called Hematite because that is what their stone is. Their power is received through those stones, and without their stone they die as it replaced their Knight Gem or Star Seed.

In the Black Moon, Wiseman "gifted" them their abilities through the orb that he has, but he can easily take their powers away. Their powers are triggered once the black moon symbol forms on their forehead and hides their identity.

Attacks and Transformation notes

Sailor Guardians and knights naturally possess the ability to fly without wings, teleport, and use their attacks without the need of using their attack phrase if they choose. Some may choose to do it out of courtesy for the person they're attacking. Knights and Sailor Guardians are the only ones who can wield some powers (e.g. teleport) without transforming, whereas major attacks such as Moon Healing Escalation requires transformation.

Superhumans must transform in order to use any of their powers, even for something as simple as teleportation.


Armor is not used in the game, not even for superhumans, knights, or Sailor Guardians. They simply do not need it, and most knights and Sailor Guardians possess a slow ability to heal outside of their transformed state. Superhumans don't, but not a single superhuman has been seen wearing armor. We therefore discourage and will often disapprove most armor.
