Elizabeth, Michael and the agents enter the vault, armed... they must be careful, as Elizabeth warned them how dangerous Barbossa can be. They walk in eerie silence...then look at the armed autobot 'Scrap'.
Michael: "You were right, miss. He created a suit."
Elizabeth Swann: "But according to the file, it should be bigger...and this one is made of scrap."
Then Elizabeth senses something, the agents separate...Michael verifies that the design is indeed different, Elizabeth approaches the darkness...Megatron lights up!
Elizabeth Swann: "It's here!"
Elizabeth flees, the agents try to protect her, but Barbossa crushes them like cockroaches, Elizabeth manages to get out of the vault. Jack is on his way.
Jack Sparrow: "Can old cybertron take it?"
Compass: "Well, the autobot is at 48% and falling, captain, the cybertron was not designed to fly continuously."
Jack Sparrow: "Keep reporting to me."
Elizabeth walks out of the offices, then Jack calls out to her.
Jack Sparrow: "Elizabeth?"
Elizabeth Swann: "Jack!...are you okay?"
Jack Sparrow: "And you?"
Elizabeth Swann: "Hector freaked out!"
Jack Sparrow: "I know, you have to...".
Suddenly the ground begins to shake. Barbossa emerges breaking the ground...Elizabeth gets a better look at Megatron.
Barbossa: ""Where do you think she's going, Miss Swann?".
Barbossa pulls a gun on Elizabeth.
Barbossa: "Let me give you a proper retirement."
Barbossa goes to shoot...at that moment, Jack arrives!
Jack Sparrow: "Argg, you're going to fucking regret it!".
Jack rams Barbossa and takes him away, they land on a bump in the road... a truck with a lady and her children stops when they see both robots, Barbossa doesn't think twice and grabs the truck and lifts it.
Barbossa: "I really love this!"
Jack Sparrow: "Leave them, Hector!".
Barbossa: "If you want it that way."
Barbossa is going to drop it on Jack, Jack quickly says.
Jack Sparrow: "Quick, all power to chest reactor."
Jack fires a beam from his chest and drives Barbossa away, barely managing to catch the truck and get them to safety... however, Barbossa returns more furious and using a motorcycle hits Jack, causing Jack to crash into a car, passengers from a nearby bus exit. Barbossa grabs Jack and lifts him to the ground.
Barbossa: "For thirty years I kept you alive."
Barbossa steps on Jack several times.
Barbossa: "I gave prestige to the Black Pearl!"
Barbossa grabs Jack and throws him against the bus.
Barbossa: "Now nothing is going to get in my way, much less you."
Barbossa pulls a projectile out of the suit, takes aim and shoots, destroying the bus, Jack is thrown... but before he falls he manages to activate the suit to fly.
Barbossa: "That's if I didn't expect it, you improved your design...just like me."
Barbossa fires up thrusters and begins to fly, Jack is stunned.
Compass: "Captain, it looks like his suit can fly."
Jack Sparrow: "I already realized, we are going to the maximum altitude."
Compass: "With fifteen percent energy... I doubt that...".
Jack Sparrow: "It's not necessary, I already calculated it... now!".
Both robots fly into the sky, Elizabeth sees them from the ground. Both Jack and Barbossa are detected by a military base.
Sergeant: "Sir, that thing is back."
Colonel: "Call Lieutenant Grooves, and send jets."
The sergeant goes to do it, but Will interrupts them.
Will Turner: "It's just an exercise, gentlemen, it's not necessary."
Sergeant: "Sure, young Turner."
Jack and Barbossa continue their flight.
Compass: "Energy 15%".
Jack Sparrow: "Go on!"
They have both almost come out of the atmosphere...the more they do it, Barbossa's suit freezes while Jack's begins to fail. Coming out almost into the stratosphere, Barbossa catches it.
Barbossa: "What a great idea Jack, but as you will notice my suit is better in every way."
Jack Sparrow: "Did you solve the freezing problem too?"
Barbossa: "What are you talking about?"
Barbossa's suit goes off.
Jack Sparrow: "It's your next lesson, savvy?".
Jack hits him on the head and Barbossa falls from the heights, Jack smiles, but Jack's suit fails, slowly turning off, descending abruptly... Jack lands on the roof of the Black Pearl offices.
Jack Sparrow: "Lizzie."
Elizabeth Swann: "Jack!...are you okay?"
Jack Sparrow: "I'm running out of energy, I'll have to remove parts of the suit, now I'm going."
Barbossa appears behind him!
Barbossa: "Another good try."
Barbossa hits Jack, Jack responds by jumping up and hitting him on the head, but Barbossa catches him and applies a bear hug...too hard.
Barbossa: "What's next?...an eternal battle between two iron warriors until the end of days and armageddon."
Jack thinks of something quick.
Jack Sparrow: "Flares!"
Jack shoots flares from the suit, causing them to stun Barbossa.
Barbossa: "How elusive you are, Jack."
Jack hides from him, silently calls out to Elizabeth.
Jack Sparrow: "Lizzie, this isn't working...you have to overload the cybertron to blow up the roof."
Elizabeth Swann: "How?"
Jack Sparrow: "You will do it, go to the center console and open all the circuits, when I come out of the roof I will let you know so you can activate the master valve button... oh, too many words".
Jack hides in the shadows.
Jack Sparrow: "Everything will come back up here."
Elizabeth Swann: "Okay, I'll do it...I'm coming in."
Jack Sparrow: "You wait for me to come off the roof, I'll buy you time."
Elizabeth activates all the circuits, while Jack jumps on Barbossa, removing a part of the suit that serves for vision.
Jack Sparrow: "I think I need this, ah, not always."
Elizabeth keeps pressing the buttons, Barbossa pulls him off her, at the same time taking off her helmet. Then Barbossa opens his suit showing himself.
Barbossa: "I admit it, I didn't like this stuff."
He then looks at the Optimus helmet.
Barbossa: "But this suit, it gives me a lot of pleasure."
Barbossa crushes the helmet and throws it at Jack, right in front of him.
Barbossa: "You did it Jack, your father would certainly be proud."
Elizabeth finished with the circuits now she waits for the button.
Elizabeth Swann: "I've got it Jack, get out of there."
Barbossa: "Today is a great day to die, isn't it, Jack?"
Barbossa shoots him with a machine gun from the arm, Jack tries to cover himself but almost falls, Elizabeth gets little debris. Elizabeth sees Jack on the roof.
Elizabeth Swann: "Jack!"
Barbossa: "How ironic life is, Jack...you set your mind to an idea, with the best of intentions...disarming the world, and you end up creating the ultimate weapon."
Jack Sparrow: "Elizabeth!"
Barbossa: "The worst things you can imagine, they were made with the best of intentions, you were their creator and these weapons will be your destruction."
Barbossa fires a missile but misses.
Barbossa: "So many loaded guns in that and you wasted your shots."
Jack looks at Elizabeth.
Jack Sparrow: "Elizabeth, the button, now!".
Elizabeth Swann: "But you said to wait."
Barbossa continues to fire but misses, (due to an earlier hit from Jack, the suit's scope was damaged).
Barbossa: "You fucking idiot, just stay still and it won't hurt...too much."
Jack Sparrow: "Already do it."
Elizabeth Swann: "But you will die."
Jack Sparrow: "Now!"
With no choice, Elizabeth presses the button... overloading the Cybertron reactor, it raises a shock wave that sends Jack flying and generates an electric shock to Barbossa... the discharge is so powerful that it leaves a sector of the city without light Then Barbossa feels bad.
Barbossa: "So cold...I feel."
Barbossa falls from the ceiling into the Cybertron reactor, exploding and irretrievably killing him in the process. Everything explodes... Jack backs away from the explosion... when everything is quiet, Jack rests on the ceiling, closing his eyes, while the cybertron in his chest flickers.
Elizabeth Swann: "Jack!"
But Jack doesn't answer.
