Kadar

I think Hound is Kadar and that he is Hinokizu.

Shiryu speculated that Hinokizu is a government man which Hound is. Laffitte that he is power user due to his ability to sink ships in giant vortices.

Kadar's ship was reported as sunk by the Sun Pirates but I think he sunk his own ship with a vortex.

Fisher Tiger said he would let Kadar go which I think is what happened. Kadar showed fear when being dangled over the sea which I think is a sign he is a Devil Fruit user.

Later on Fisher Tiger reprimanded Arlong and Jinbei for going too far I think further supporting that they didn't sink Kadar's ship.

I think Hound is the one who gave Luffy the food and has been sabotaging the government for a while.

I think is responsible for Luffy's new wanted poster keeping his initial and using the Nika picture.

I think he hacked the den den mushi to take the picture of Cobra's assassination and sent it to Morgans.

I think leaked the government's plot to assassinate Vegapunk as well.

I think he has the tell-tale signs of a traitor. Questionable dialogue he suggested canceling the Buster Call and inaction he wasn't shown fighting at all.

I think the reason he is a traitor is that he is the child of one of Saturn's test subjects. I think he inherited the chemical and was successful.

It was hinted in the manga and more in the anime that Law has a connection to Hinokizu. White Lead Disease was brought up when Kuma was looking for a cure to Sapphire Scales.

I think Saturn's experiments are the source of the disease and that it being known in the "lower world" is a sign he has been doing them for a while and releasing test subjects.

I think Kadar is the marine that captured Ginny and will rectify it by killing Saturn.

I think it has been forecasted that he will die. He brought up the irony of Bonney being killed by Kuma's own clone. I think Saturn will suffer poetic justice and be killed by the results of his own experiment.

I think Weevil is the man with the burn scar.

Miss Buckin claiming that Vegapunk could prove Weevil's kinship to Whitebeard adds support to the theory he is a failed Whitebeard clone.

She herself was successfully cloned by MADS which she was part of. And was a Rocks Pirate meaning she had access to Whitbeard's bloodline elements.

If Weevil is a clone of Whitebeard he could have his memories which would be significant.

The last road ponelgyph was originally located on Fish-Man Island.

Which was previously under the protection of Whitbeard who Roger revealed some of the secrets of the world to. I think it's very possible he knew the last road ponelgyph was there meaning Weevil could too.

Since Weevil was captured by Greenbull there is a theory he will get a glow up.

Which would be a cool callback to this scene. But I think Weevil is a character that was already introduced.

I think Weevil is Kadar a rear admiral that fought the Sun Pirates. I think there is a mystery around since his ship was sunk even though Fisher Tiger promised to let him go.

Shiryu speculates that the man with the burn scar is a government man. Laffitte that he is a power user, since he rides in an all-black ship that swallows enemy ships in gigantic vortex if they wander to close. Kadar is a marine and his ship was sunk.

I think Kizaru is another hint, he took the reports for Kadar and Weevil which I think links the two.

Again I don't think the Sun Pirates sunk Kadar's ship. Fisher Tiger berated Arlong and JInbe for going too far. Arlong said he only killed one or two people.

I think Weevil ate the Hito Hito no Mi, Model: Umibozu. The umibozu is a yokai that takes the form of a monk that sinks ships. The umibozu was mentioned a few times.

Similar to Onyudo (Wadatsumi's epithet was Onyudo) before it appeared as a human zoan fruit.

I think Weevil awakened and his zoan powers consumed his mind which is why he is simple minded like the Jailer Beasts.

It think Weevil will regain mind utilizing powerful haki.

If my theory is true I think Weevil got disillusioned with the marines like Diez Barrels, went awol and sunk his own ship.

I think he Awakened in Wano. His neck scar looks like it could have been inflicted by Queen's collar. Apparently body parts can be reattached in Wano and Weevil's arm looks reattached.

I think Kaido tried to recruit him to army so sent him to the Prisoner Mine to break his spirit but he escaped.

I think Weevil's burn scar will be on his back where Whitebeard had his Jolly Roger tattooed.

I have a theory that Weevil is Rear Admiral Kadar.

He was recently captured by Aramaki and I think his his true identity will be revealed.

Aramaki has the ability to drain liquid from a human body. And was able to return Shinobu to how she looked 20 years ago. I think he will do the same to Weevil.

I think Weevil's scars hint that he was in Wano. The scar around his neck seems like it could have been inflicted by Queen's collar.

And the scar on his left arm looks like it could have been severed. The Mountain God was somehow reattached. I think maybe there is a Devil Fruit power that has medical applications similar to the Ope Ope no Mi that exists in Wano.

The reason I think him being in Wano is in important is because I think Weevil ate a SMILE and became an artificial zoan.

I think Weevil is an Awakened SMILE user which would explain why he is dim-witted.

Haki can overcome Devil Fruit abilities so I think Weevil will use Haki to return to normal.

I think there is a mystery surrounding Kadar. His ship got sank even though Fisher Tiger promised the Sun Pirates would spare them.

It was even reiterated that Fisher Tiger did not want the Sun Pirates taking lives. Which makes me think there is more to it.

I think Kizaru hearing the report about Weevil and hearing the report about Kadar 15 years ago is a clue to this.

I think Weevil is the pirate Shanks talked to the Gorosei about. I think it makes sense if the pirate is connected to them and the Shichibukai worked for the World Goverment. The meeting reminded me of Shanks' one with Whitebeard.
