Let's start simple, for some reason, the moon(s) seems to be a CONTINOUSLY prevalent motif in the story (Enel, Ohara, Minks, all the wano "moon" names like shimotsuki, Kurozumi, Kozuki, Amatsuki, etc.)

A RECURRING flag or symbol (in Alabasta, Skypeia, and wano/Zou, ALL countries heavily related to ancient kingdom) is the the big circle with EIGHT smaller circles orbiting it. This is assumed to be 8 moons, as shown in Ohara (Robin Flashback)

Now something very interesting that people caught on to, was the number of moons correspond to the number of races in One Piece's World: Long-limb, 3-Eye, Giants, fishmen, dwarves, Minks, skypeans, and "King's" race)

Now some say that each race came from a moon in the one piece, so I went further in my Lab to investigate this and the findings are MINDBLOWING

This is what I call Super Saiyan 1

It's commonly accepted that there are EIGHT planets (excluding earth) in our solar system. Interestingly, each PLANET has its OWN moons that mean different things. The 8 planets correspond to the 8 moons in one piece. Let's start with earth and its moon.

Our "regular" moon is heavily related to skypeians as we know they actually CAME from there and they called it Vearth. Its safe to say this is the Skypeian moon

Now the second planet and its moons. Neptune has 3 moons, one of which is called Triton. Triton is a mythological creature that is Half-human half-fish. Fishmen!

Third planet Jupiter has 2 big moons called Io and Callisto, both names of nymphs (FOREST DWELLING SPIRITS) that were TURNED into MAMMALS (a Cow, and a bear Respectively) MINKS! I swear I'm not making this shit up

And this is what I like to call Super Saiyan 2!!

Whats crazy is the pattern Continues!! Saturn has several moons based on the names of TITANS. And if that didn't give it away, Mimas, one of the largest moons of saturn, is based on Mimas of the Giant race in Greek mythology!!

AND THIS.. IS TO GO EVEN FURTHER BEYOND!!!

The most important moons of Uranus are Oberon and Titania. And if you watch Fairy Tail this should CLICK. Oberon and Titania were (Greek mythology) the KING and QUEEN OF FAIRIES. Remember what the dwarves were CONSTANTLY called in dressrosa?

HAAAAAAAAAAAAAAAAAA!!!!!!

Mars has only 2 moons, Phobos and Deimos. These 2 respectively mean Fear and Terror. In popular culture, they are depicted as Devils or Crows

You'll recognize them in sailor moon as the the 2 ravens with Black wings accompanying Sailor Mars. There's also a 1970 manga called Bride of Deimos where Deimos is turned into a devil-like creature with BLACK FEATHER WINGS. Ladies and gentlemen... We got him.

And this... This is Super Saiyan 3

I'm only missing 3-eyed tribe and long limb moons but my research is not done and I just couldn't wait to share this before it's complete maybe we can find them together
