People have been questioning Law's motivations for a long time, this all started when Law appeared to save Luffy at Marineford.
His motivations for doing this seemed suspicious
Things seemed to become more clear when we saw him again in Punk Hazard and he proposed an alliance with Luffy.
Law apparently saved him in order to form an alliance later on.
Law had been working on this plan for some time, he had even gone to the lengths of obtaining Warlords status to enable himself to get on the inside with Ceaser
We now know that Law had an ulterior motive in this plan and it was not the downfall of any of the Yonko but his revenge on Doflamingo for the death of Corazon.
We learned later that despite any ambition he might have had to take down a Yonkou, he fully expected to die in his attempts to take down Doflamingo and had accepted this was the most likely outcome.
However, Law's fate was changed in this moment, when Luffy prevented Doflamingo from killing him.
Through this they were able to defeat Doflamingo and suddenly the plan to take down a Yonko seemed more realistic. They began to set their sights on Wano
Now Wano is in full motion and the battle against not one but two Yonko has begun. Soon the conditions of the original alliances will be fulfilled. So what will Law do next?
Since his ambition for revenge on Doflamingo was fulfilled, Law has established a new motive. He wants to learn the truth of the Will of D.
This is actually something he discussed with Robin at some point, even admitting to her that he was a member of the D. clan
The dialogue between them here is quite intriguing.
Law trusts Robin, Luffy doesn't care & they share a motivation to learn about the D. clan
This gives us a clear motivation for Law to follow after Wano but what role will he take to pursue it?
That brings us to the first possibility, the popular theory that Law is a member the secret marine organisation, Sword
This idea originally stems from this interaction between Law and Drake at Saboady, Law seems to be familiar with Drake.
We later learned that Law and Drake were actually connected by past events. They were both on Minion Island on the day Corazon gave the Op Op no Mi to Law and Doflamingo killed him.
The man who had possessed the fruit, was Drake's father. Daz Barrels
Drake escaped the island just before Law did. Interestingly, the lie Corazon tells to Doflamingo actually most likely explains what then happened to Drake.
This suspicion was furthered when Drake seemed to free Law from imprisonment in Wano
Law also has a connection to Coby, the Rocky Port Incident. This is how Law obtained his Warlord status to infiltrate Punk Hazard.
Coby was the one who protected the citizens in this incident.
Some would say, that's a cover for them to meet.
There is more to the theory of Law being with Sword but let's not focus too much on that, there are other possibilities. For now, Law being with Sword seems one of the stronger options for his path forward.
For a more thorough break down of that theory, check out @RandyTroy
The next and seemingly most straight forward option is that Law simply remains an ally to the Luffy, some would argue he'd even join the crew
Personally, I think this is a boring option and if Law were to become a subordinate to Luffy, it would diminish his role in my opinion
If Law doesn't remain an ally, then what will his allegiances be, if any? Will he be friend or foe.
Now we have to address, the possibility of betrayal
Law's loyalty has been called into question before as well. After Drake had helped him escape and turns the tables on Hawkins, Hawkins questioned Law's intentions, Law only said this.
But why would Law betray Luffy? He literally owes him his life and the fulfilment of his life long ambition. There would have to be a strong motivation.
If this were to happen, it would most likely be because Luffy's actions clash with Law's motivation to learn the truth
The strongest motivation for Law to betray Luffy is to obtain the Road Poneglyphs and this is the most likely way in which Law would do so.
He was there on Zou when they learned about the Road Poneglyphs
It's possible that he may already have stolen rubbings of the two that the Straw Hats got from Zou and Whole Cake Island.
Law was also searching for the Road Poneglyph in Onigashima, he comments that the one he found is not one of them
It's possible then that when it comes down to it, Law may have cause to turn on Luffy to ensure he is able to fulfil his goal. This could happen when they find the last one.
This could happen at Loadstar Island
Loadstar --> last road
However, there are other possibilities that don't necessarily involve Law betraying Luffy.
There is also the implication made by Doflamingo, that Law has the potential to control Mariejois' national treasure & there is some potentially major significance to his personality swap
I was going to sit on this theory until Halloween and drop it as a special but it seems like this is a good time to talk about it now.
Let's get started
Whether or not the raid will fail has been a popular debate throughout the arc, most notably, people like @mrmorjman have backed the idea that it will fail.
The main reasoning for this, is the apparent overwhelming odds against the alliance.
As 1029 approaches next week we get closer to Ch 130 & the possibility of @yuderon1's prediction on Vegapunk coming true. My own Vegapunk theory is attached to this and soon we may have an answer on his identity.
He may not be the CP0 leader but i'm almost certain he is coming!
I'm not sure how many people notice this but all of Vegapunk's experiments have a link to Wano.
The first time we hear the name, 'Joyboy' is when Robin found the Poneglyph in Fishman Island.
She comments that it seems like an apology letter. She wonders who this Joyboy could be apologising to.
Neptune later explains that that passage is addressed to the mermaid princess.
Through this conversation with Neptune, Robin asks if the hidden name of the mermaid princess might be Poseidon. Remembering the poneglyph in Skypiea indicated that Poseidon would be found on Fishman Island.
The first time we hear mention of the Will of D. Is in Drum Island. Kureha talks to Dolton about Roger's real name. Gol D. Roger.
"So the Will of D. Still lives?"
The next time we hear about 'D.' It's from Robin. After Luffy's initial defeat by Crocodile, she pulls him in the sand and asks him. Why do those with D in their name always fight?
Luffy is quite oblivious as to what the hell she's talking about
