Black and blood-red metal interlocked to form a hideous, terrifying weapon of world destruction.
Its main body resembled an enormous sword suspended point-down in the void, its blade engraved with dense ancient markings, each slowly glowing with dark golden light.
At its hilt stood a massive ring-shaped structure, countless metal rings layered together like a closed giant eye.
Dozens of secondary turrets extended from its body, every barrel aimed at the blue planet below.
Extremely ancient, dark red patterns flowed across its metal surface like living blood vessels, surging with an energy that did not belong to this world.

Those runes spread from Natsu's palm across every inch of Uranus's metal surface.
