Netero’s Dead-Man Rose

Netero’s death automatically detonates the cheap, mass-produced Miniature Rose implanted in his body; its persistent poison later kills Meruem and the guards who rescue him.

Proliferated destructive technology lets a weaker actor retain decisive power, while second-order effects overwhelm the apparent endpoint of the confrontation.

This is primarily a WMD-proliferation analogy rather than an AI-alignment scenario.
