Shanks never had any intention to posses any DF power from the very beginning. Roger was his role model. None of his crews has shown to have DF power. It is doubtful that Shanks already knew that gomu-gomu no mi was actually hito-hito no mi, model: Nika when he stole it from who's who since not hinted so far.

This is just another wild theory. The original source so far has introduced 22 (iirc) logia-tye DF, and not single one has shown undergo into awakening. It is hinted by Dr Vegapunk that logia-type DF may never awaken because of difference in nature than other types of DF.

Whitebeard's former weapon, Murakumogiri is not a sword but Halberd (or Naginata), but Oda himself added that this weapon is one of the 12 Saijo O wazamono. And so far, 5 out of 12 of them already revealed. This means that the remainings might not be all swords or blades.

Enel's return will make plot more chaotic. Why? What's his reason? There is more reasonable character to come to Elbaf and bring destruction, AKAINU. After Marineford arc, he never showed up. Other admirals have shown action in the series; Fujitora and Greenbull's fight in Marijoa, Borsalino's defeat in Egghead, and former admiral Kuzan in Hachinosu against Garp. Then Akainu just sit still and barking under his table?? Lmao

Back in Whole cake arc, when BigMom enraged for the first time, showed similar strength that fans speculate to possess DF that can manipulate fire and thunder, but later revealed that it was her power to manipulate soul. Clearly, her DF has no direct control to neither fire or thunder. This might be the same with Loki's DF.

When Loki first introduced to the series, the silhouette looked goofy too, also Big Mom and Gorosei demonic form. So if Imu's going to be biggest joke, then it will be no joke.

If you relate the fact in one piece world, this is very absurd. Remember how Garp and Aokiji trained themselves punching scrapped marine battleship with only their fists and Garp did say no haki allowed on his training. Then someone who stays on higher level was losing one of his arm to a mere coastal fish. Even without haki, Shanks could have hold himself without losing his arm.

It has been mentioned previously that there are 4 gods in one piece world. So far only one revealed. The story is at final saga, then suddenly overpowered characters appear out of nowhere, oddly rivaling long-mentioned overpowered ones like Shanks and Blackbeard.

More weird DF brought into the series with label 'mythical beast', though those beasts never really exist anywhere in one piece folklore. Clear hint that the story goes just aimed to fulfill fans' hype instead of real-thought plot.

Straw hats, and Luffy to be more precise, doesn't need to reach Almighty level of power to be the strongest being in one piece world. It has been stated by Mihawk long ago, back in Marineford war arc that Luffy possess the greatest power in the ocean. In the end, what if Luffy tag duo ally with Shanks, not much to say that they are invincible.

The phrase 'devil fruits', so why they are so called that way? If DFs are truly originated from Mariejoa, perhaps Imu is the one who takes responsibility in bringing the power into one piece world.
