Steamboy (2005) Timeline Explained – Every Event in Order

Eddy attacks the Great Exhibition because he has been manipulated by Stephenson, who plans to exploit the Steam Ball's power for weapons. After Ray presents the ball to Stephenson, Eddy realizes his creation is being used for warmongering rather than helping humanity. Enraged by this betrayal, he prematurely activates the Steam Castle's full potential, transforming it into a weapon to destroy the British military and expose their true intentions.

Eddy transforms the Steam Castle into a floating fortress when he activates its true potential. The castle is powered by three Steam Balls, and when all three are activated together, the massive structure becomes airborne.

Foreshadowing: Ray learns earlier that the castle is powered by three Steam Balls and represents his father's dream of limitless power.

They seeks to acquire the Steam Ball to complete their arsenal of steam-powered weaponry, which they plan to profit from by supplying arms to nations.

Foreshadowing: Lloyd secretly shows Ray the hidden armory filled with massive steam war machines during the exhibition preparations.

Foreshadowing: Ray previously escaped on a steam-powered monowheel, demonstrating his skill with steam vehicles.

Lloyd opposes the Steam Castle because he knows it will be weaponized for war rather than used for humanity's benefit. He spent years trying to prevent the technology from falling into the wrong hands, which is why he entrusted the single Steam Ball to Ray. Lloyd understands that Eddy's creation, while technologically impressive, represents dangerous scientific arrogance that could cause massive destruction.

Foreshadowing: Lloyd reveals the dark legacy of the Steam Ball to Ray, warning him about its connection to Eddy's injuries.
