Dude, this is making so much sense to me right now.
Right?!
To go even further, kid Blackbeard was shown crying under a moon. The moons gravity affects tides. The previous gura user had a crescent moon moustache lmao.
We also have a crescent moon hunter In his crew, crescent moon hair gatling, crescent moon tattoos for kozuki alliance and crescent moon islands are a pirate story staple too.
Nika is the sun God, blackbeard faced the "sun emperor" Ace and snuffed out his fire, his light like a solar eclipse in a way. Blackbeard can blot out the sun and potentially cancel out the nika transformation too. He might be the moon god, there's always one half of the moon that's darker and colder as it's not facing the sun and receiving its heat, the light too.
Blackbeard has lived in the shadows his whole life and now we know he's living in the shadow of the most diabolical, dangerous pirate ever, his own father. no wonder Oda is associating moria with him too, moria who uses rocks pirates corpses as soldier puppets too for revenge on a former rocks pirate too ironically.
Blackbeard said the yami yami was the most evil fruit and it called out to him like its sentient potentially. What do know about zoans again just before or around when luffy awakened his fruit?
Blackbeard could be the moon God, the darker side of the moon, the neglected one swallowed by darkness, the isolating, insanity causing endless void of space, the atmpspheric vaccuum etc.
Like Blackbeard I'm very sleep deprived atm so forgive me too here please lmao.
Oda said beckmann was like the moon to Shanks too. and we have dark king Rayleigh too.
Some wano clans like amatsuki (tokis) are moon themed too. zoro is moon themed too and also themed with number three like blackbeard.
