I don't know where to start…..
I advise you wait for the scanlation though.
! For one, even two years before he reached Raftel, he had already located an ancient weapon capable of destroying the world.
Shiki wanted Roger to join forces with him, claiming that between his pirate army and the ancient weapon, they could rule the world.
Roger declines the offer, saying he's not interested in ruling the world. There's no point of being a pirate if he can't act freely as he wants.
! Shiki: So you're saying, you want to die right here and now!!
Roger: No, I'm saying we're gonna beat down all of you!!
! Shiki's forces were overwhelming in number to Roger's.
But a sudden storm arrived at the battlefield, saving Roger's crew.
Half of Shiki's forces were sunk, and a steering wheel got stuck in Shiki's head, nearly killing him.
! Shiki seemed to regard Roger very highly after this, and could not believe he has been captured by the marines.
So he stormed into Marineford, demanding to let him see Roger.
He doesn't care about this whole "Pirate King" name given to Roger, he feels he's the only man equal to him.
Garp and Sengoku fights Shiki, and the battle between these three alone destroyed half of the entire Marineford.
! Looks like Shiki's heart was broken after the capture, as he muttered to himself "Why did you die on me, Roger…!!" in his cell in Impel Down.
He feels this "new era" is bunch of bullcrap, and the pirates should be the rulers of the ocean.
! Later, we get to see Magellan as Sub Chief Warden, answering to the Chief Warden of the time.
So Magellan was in the same position Hannyabal is in currently. (We don't get to see the Chief Warden's face, only Magellan taking orders)
The shackes on Shiki's feet was indeed made of Seastones. (Shiki cut his feet off to escape, of course)
! At Shiki and Whitebeard's meeting
Shiki: How's the sea without Roger? No one stands in our way anymore...
It seems the era belongs to you now, Whitebeard?
Whitebeard: If you came here to chat bullshit Shiki, I'll sink you to the bottom of the ocean right now!
Shiki: Jihahahahaha!! Glad to see you're still an asshole.
I plan to go into hiding for a while. I'll show this lukewarm era the fear of a true pirate...!!
Whitebeard: You're up to no good again....
! Shiki goes in hiding for 20 years, while his comrade Dr. Indigo works on a research that takes 20 years.
Shiki will unveil his scheme to throw the world into chaos 20 years from now.....
(continued to the movie)
Shiki's got a lot of character, he's awesome.
He's not just a generic villain, he feels very much like another One Piece character.
It's got Oda's signature written all over him, unlike many other non-Oda written movie original characters.
God Movie 10 is gonna be awesome.
