That's a solid close to the Water 7 → Post-Enies Lobby section. You've hit every canon point and blended Ben's place in naturally. Here's a clean, polished version that keeps your pacing, dialogue, and tone while fixing grammar and flow:
---
Screen 1 — Return to Water 7
After their victory at Enies Lobby, the Straw Hat Pirates return to Water 7 as heroes — even though the world now brands them one of the most dangerous pirate crews alive for declaring war on the World Government.
The crew rests and repairs in the city, still processing everything — Robin's rescue, the loss of the Going Merry, and their uncertain future.
Ben: "I think it's time we build a new ship."
---
Screen 2 — Grandfather and Grandson
While the Straw Hats are recovering, a Marine ship docks in the harbor.
Leading it is Vice Admiral Monkey D. Garp, the legendary Marine hero.
Instead of attacking, he walks straight into Iceburg's dockyard, rears back, and punches Luffy so hard the ground cracks.
> Garp: "Why didn't you tell me you'd become such a big-shot pirate, you idiot grandson?!"
Everyone freezes.
Then Garp casually adds:
> Garp: "Oh, and by the way — I'm your grandpa."
The crew explodes in disbelief.
Zoro: "Grandpa?!"
Sanji: "No way the Marine hero's related to him."
Luffy (grinning): "Yeah, he's my grandpa."
---
Who is Garp?
Monkey D. Garp — the man who once cornered Gol D. Roger, the Pirate King, countless times.
A Marine hero with his own brand of justice who trained Luffy (and Ace) by throwing them into jungles, cliffs, and even tying them to balloons to "make them strong."
He still wishes Luffy had become a Marine.
---
The Koby and Helmeppo Reunion
Garp isn't alone. With him are Koby and Helmeppo, the Marines Luffy met in the beginning of his journey.
They've changed completely: older, stronger, and disciplined after training under Garp.
Koby: "Captain Luffy, thank you… you made me chase my dream. I'll be an admiral one day!"
Helmeppo: "And I'm not the spoiled brat you remember."
The old friends shake hands — allies by heart, enemies by duty.
Then Garp drops another bombshell:
> Garp: "Your father's the most wanted man in the world — Monkey D. Dragon, leader of the Revolutionary Army.**"
Ben (wide-eyed): "Your dad's the leader of the revolution? That's… insanely powerful."
Luffy (shrugs): "Yeah. He's cool."
---
Screen 3 — A Goodbye and a New Beginning
The Going Merry drifts away in flames.
The crew watches in silence.
Even Ben lowers his head.
Ben (quietly): "She saved us more times than we deserved. Even heroes break eventually."
Franky: "Then we'll build her successor — a ship worthy of every sea."
He drops a pile of rare lumber onto the dock.
Franky: "Adam Wood — the strongest material on the planet! She'll have a soul."
Ben (grinning): "Then let's give her a heart too."
---
Screen 4 — Ben's Role in Construction
Forms Used: Upgrade, Grey Matter, Diamondhead
Franky handles design and craftsmanship.
Ben brings alien science.
Upgrade merges with the framework, mapping every stress point.
Grey Matter calculates balance, drag, and resistance.
Diamondhead forges crystal reinforcement inside the Adam Wood frame.
Franky: "You're reading my mind, bro!"
Ben (as Grey Matter): "Nah, just better math."
Franky: "That's SUPER!"
Hidden features follow:
Solar collectors to feed Franky's Cola engines.
An Omnitrix interface in the helm for self-diagnosis.
Diamondhead armor under the hull.
A hybrid propulsion booster for emergency bursts.
---
Screen 5 — The Thousand Sunny Launch
Weeks later, sunlight glints off gold-and-white wood.
The Thousand Sunny is born — a blend of Franky's passion and Ben's technology.
Franky: "She's my dream ship — strong, free, and super!"
Ben: "Built to last forever. Just like us."
Luffy: "Let's set sail, Sunny!"
Ben (placing a hand on the rail): "Merry carried our hearts. Sunny will carry our future."
> Ben: "Some things you build with your hands. Others — with your soul."
---
Screen 6 — Franky Joins and Usopp Returns
Franky initially refuses Luffy's offer, but after the Franky Family and Iceburg pull their prank (stealing his underwear), he gives in — laughing and crying — and joins as shipwright of the Straw Hat Pirates.
Meanwhile, Usopp, guilt-ridden over leaving, finally bows and shouts:
> Usopp: "I want to sail with you again!"
Luffy (smiling): "Of course you can."
The crew bursts out laughing — their family is whole again.
---
Screen 7 — The World Reacts
News of Enies Lobby shocks the world.
Luffy: 300,000,000 Berries
Zoro: 120,000,000 Berries
Ben Tennyson: 420,000,000 Berries
> "Alien of Justice — The Being Who Wields a Thousand Forms"
"Subject wields an unknown transformation device. Classified Omega Weapon."
Ben (seeing his poster): "I'm officially worth more than a small country."
Nami: "Then pay off part of our debt."
---
Final Note
Elsewhere, Ace continues chasing Blackbeard, who betrayed Whitebeard's crew — setting the stage for the storm to come.
As the Thousand Sunny glides into the open sea, the Omnitrix blinks red.
Ben: "Red mode again… looks like trouble's coming."
Be continued…
