Which character would you like to get a spinoff or movie?

Hey guys I was sitting thinking about how many of the side characters in One Piece are very interesting and I'd like to see what there origins are. So I was wondering that if they made a movie or a spinoff manga series(like fairy tail zero) which character or characters would guys like to see get their own story.

My personal top 3 would be Garp, Shanks, and Sabo. I feel like they would have the coolest back stories.

Let's see what you guys think.
