When people say that you can get other characters like Aokijii or Enel they're talking about the japanese version. So don't try wasting your time trying to get a new character that does not yet exist in the manga world of the U.S. But here are some of the things that are unlockable.
Story mode: Very hard mode Voices: all characters Characters: Mihawk, shanks, chopper, and ms.sunday.
Well I was fighting nami in story mode and when I started, on top left, where sanjis face is, hearts were his eyes. When you use shoulder shank crank (special attack) He says, " I just can't hold it in. " When it shows the Special attack background where he does his move his eyes are normal, not mad looking! And he dosent say whatever he says at the 2nd attack. If you do the 3, 2, 1, the glass wont break, he says, " I can't stand to hurt you more! " I thought it was funny, if you see the 3, 2,1, tell me what he says and does, ok?
When you use the attack clone clone memory if you hit these buttons next to the descriptions you will get differrent effects.
Mr. 7- Hit x,x,x,x,o while holding L1. (this makes you turn into a wierd guy with a george washington wig style with a gun, hit o repeatidly to fire the gun.)
Mr. 8- Hit x,x,x,o while holding L1 (this makes you turn into another guy with a george washington wig, but it automaticly attacks which is where he shoots little needles out of the wig like a gattling gun.)
Mr. 9- Hit x,x,o while holding L1 (this makes you turn into a guy with a YELLOW george washington wig, and instead of having a gun you'll have a BAZOOKA which you fire exactly like the gun, by hitting the o button repeatidly.)
