War-torn kingdoms collapsing into zombie apocalypse, and somehow it's the petty tyrant behind the safe walls you actually need to fear. SD Gundam takes the Three Kingdoms story and strips it down to the core conflict that matters: survival means nothing if the people running the fortified cities are already dead inside. The tiny robot aesthetics make the collapse feel weirdly intimate, like watching civilization crumble through a dollhouse window.
A plague of yellow zombies ravages a war-torn world, forcing survivors behind fortress walls where they wait for salvation that never comes. Inside these cramped cities, corrupt lords like Dong Zhuo abuse their power without consequence, crushing hope with every decree. Three unlikely heroes emerge from the darkness: Liu Bei Unicorn Gundam, a warrior seeking justice, crosses paths with the fierce Guan Yu Nu Gundam and the spirited Zhang Fei God Gundam. Bound by shared conviction rather than blood, they refuse to accept the world's slow decay. Together, they pilot their Gundam mechas and challenge the rot festering at the heart of civilization, fighting both the mindless zombie hordes and the tyrannical forces that profit from chaos. Their rebellion ignites something deeper than rebellion. As they clash against overwhelming odds, these three warriors discover that their determination might actually reshape history itself. What begins as a desperate struggle for survival becomes a revolution that questions everything about power, sacrifice, and what it truly means to be a hero in a broken world.
