Wano Country, the underground armory beneath the Flower Capital.
Huge mechanical crane arms slid along their tracks, grinding with a dull metallic rumble.
Tony Stark hovered thirty meters above the ground, holding a cup of black coffee.
Beneath his feet lay a two-thousand-meter-long behemoth.
It was the ultimate floating battleship under assembly, code-named "Destroyer."
"JARVIS, increase the hydraulic pressure in mechanical arm three by five percent."
"There's still a tolerance of zero point zero two millimeters in the port-side main keel joint."
Tony sipped his coffee and issued instructions through his headset.
"If these clunky machines screw up again, I'm replacing their control chips with potatoes."
Data cascaded down the holographic screen.
In the workshop below, Vegapunk and his six clones were working flat out.
The old man had a glowing oversized head and held an electronic wrench.
"Tony! Stop nitpicking up there!"
"I've finished translating all of Leviathan's core algorithms!"
Vegapunk wiped the grease off his forehead and pressed a red button.
Pale blue electromagnetic ripples suddenly lit up the composite armor plates covering the battleship.
It was a defensive mesh combining a spatial deflection field with a seastone-vibranium composite.
"See that?"
"The ancient Leviathan's original shield had a response delay of zero point zero zero four seconds."
"I've eliminated that flaw with high-frequency pulses from the Arc Reactor!"
Vegapunk pointed at the holographic model, gesticulating excitedly.
"Seastone particles suppress devil fruit abilities."
"Vibranium absorbs purely physical kinetic impacts."
"The spatial field deflects large-scale energy bombardments straight into a void dimension."
"Even if the World Government brings Uranus here, they won't break through this shell easily!"
Tony guided his armor down slowly beside him.
"You make the theoretical data sound spectacular."
"Without live-fire testing, this thing would only count as a half-finished product at Stark Industries."
Tony set down
