You all return to Isla de Muerta. 

Jack Sparrow: Okay lass, you stay here with the ship. 

Elizabeth: I'll do no such thing! Will could die in there.

Jack Sparrow: Dear William is fine. Trust me.

Elizabeth: I am not a fool, Jack.

(Y/N): You can trust us. 

Elizabeth: Yes. (Y/N), Ruby, Weiss, Blake, Yang, Sora, Donald, Goofy, please bring William back. 

Yang: Hey, anything for a fellow chica. 

You guys go with Jack to confront Barbossa and his crew! 

The villainous pirate captain is by the treasure mountain again, this time with Will as his captive. 

Barbossa: Now, let's be tryin' this again! The last of the Aztec treasure has been returned.

He points his knife to Will. 

Barbossa: And now, the blood will be repaid to free us from this curse forever! This time for sure!

However, you guys make an entrance! 

(Y/N): AHOY MATEYS! 

Barbossa: Not possible.

Donald: Not probable! We're alive and we're pirates!

(Y/N): (Y/N) (L/N)! 

Sora: Sora! 

Jack Sparrow: Captain Jack Sparrow! 

Ruby: Ruby Rose! 

Weiss: Weiss Schnee! 

Blake: Blake Belladonna! 

Yang: Yang Xiao Long! 

Donald: Donald Duck! 

Goofy: And Goofy too! 

Barbossa: So you want to play pirate? Best save the playacting for the nursery. After them!

The pirates begin to attack as you guys get to fighting them, though Jack is clashing with Barbossa! 

Barbossa: You can't beat me Jack. 

Jack stabbed Barbossa, only for him to sigh and stab him back! 

(Y/N): JACK!! 

However, Jack stepped into the moonlight and came out as a Skeleton Pirate. 

Jack Sparrow: Couldn't resist, mate. 

(Y/N): HA! That was clever alright! 

Barbossa: Show yourself, Pete! The tide has changed.

Pete: Told ya you needed my help! 

He whistled for Heartless! 

(Y/N): Well, here we go!

Ruby: AVAST!!! 

You guys begin to fight off the Heartless, and Weiss freed Will. 

Weiss: You okay? 

Will: Yes, they didn't hurt me. Wait, who's side is Jack on? 

Blake: Whatever benefits him at the m- LOOK OUT! 

Blake pulled them back as Jacoby appeared with a bunch of bombs, nearly blowing them up. 

Jacoby: I'm going to teach you the meaning of pain! 

???: You like pain? 

Elizabeth appeared and whacked him across the head with an oar! 

Elizabeth: Try wearing a dress. 

Weiss: Wow, that was- Something. 

You soon run into Weatherby. 

Weatherby: Going somewhere? 

(Y/N): Ha! I'm not scared of you. Come at me. 

He charged, and you just lit him on fire! 

Weatherby: AAAAAAAAAAAAAAAARGH!! 

At the same time, Sora was helping Jack fight against Barbossa. 

Barbossa: Oh, just give it up! I- 

He was whacked across the head by Sora, with his head spinning. 

Barbossa: AAAAAAAAAAAAAARGH!! 

While the others were keeping the Heartless, Weatherby, Monk, and Jacoby at bay, Ruby had an idea! 

Ruby: Hey! Elizabeth! Toss me that oar! 

(Y/N): Ruby, what are you- 

Ruby: Just a little something! HEY STUPID PIRATES! You guys couldn't even raid a pier! (blowing raspberry!) 

The trio charged at her, only to be rammed together by the oar. 

They looked and soon enough- 

(Y/N): HA! 

You then kicked one of Jacoby's bombs into his open stomach and made sure they were out of the moonlight, and- 

Jacoby: No, fair. 

KABOOM! 

The three were blown up! 

Then when you guys were going to join Jack in his fight, Barbossa took out his pistol, though at the same time, Jack threw the Medallions at Will, who caught them, and he cut his hand to put his blood on them. 

Before Barbossa could fire, Jack shot him first! 

Barbossa: For ten years, you've carried that pistol, and now you've wasted your shot. 

Will: He didn't waste it. 

Will dropped the gold into the chest, and soon Barbossa found himself coughing up blood. 

He looked down at his body and saw more blood coming out of the area where he was shot. 

Barbossa: I feel...cold.

He then collapsed on the treasure, dead. 

(Y/N): (Sigh) Poor bastard. He finally got what he wanted. 

Soon... 

You guys left back onto the Black Pearl. Barbossa and his crew were finished! 

Will: What's next for you then, Jack? 

Jack Sparrow: Whatever I want, now that the Pearl is mine again.

Will: That she is. Thank you, Jack.

(Y/N): Good luck out there. 

Ruby: May the legend of Jack Sparrow continue! 

Weiss: As long as there is no double-crossing involved. 

Jack Sparrow: Farewell mates. 

Jack took off on the Black Pearl, singing "A Pirate's Life for me!"

Though Jack's compass reveals another gateway for you and Sora to open! 

Will: Elizabeth, I- 

Elizabeth just hugged him. 

Elizabeth: Thank you, Will. 

(Y/N): AWWW! 

Blake: Those two were meant to be, after all. 

You guys got ready to go to the next world, which was- 

(Y/N): HEY! IT'S AGRABAH!
