Fiction

Dreamwave Generation One continuity

On May 4, 1998, the human world leaders, tired of being caught in the crossfire of the Great War, contravened a summit. At the summit, the World Leaders unanimously voted in favor of Operation Liberation, a massive endeavor whereby the various major world powers would militarize and begin a unified assault on the Decepticons.

The final battle itself was led by the mighty Optimus Prime and despite the Autobots' greatest efforts, human casualties were incredibly high. The battle raged for days, with the Autobots' assaults unable to penetrate the Decepticon lines and the humans dying in droves thanks to the Decepticons' energon-powered laser cannons.

It was to be a self-sacrifice (and for once, not Prime's) that would aid the forces of humanity and Autobot alike. A Canadian airforce pilot, Rudy "Red" Kingsley flew his fighter jet into the heart of the Decepticons' headquarters. The jet exploded, killing Kingsley and injuring and rattling the Decepticon forces enough that the alliance was able to defeat and capture the Decepticons, ending the Great War for good.
