Fighting game design depends upon balancing character movesets such that no single fighter can achieve universal dominance without strategic opposition. The Mortal Kombat franchise specifically published expansion packs featuring additional playable characters, each carefully calibrated through playtesting to maintain competitive viability. The design principle assumes that any character can be defeated through appropriate opponent selection and strategy application.

In 2014, NetherRealm Studios designer John Torres was planning the Mortal Kombat X expansion character roster when he encountered an unexpected constraint. The balance algorithm flagged a proposed character design as incapable of functioning within the established competitive framework—not because the design was overpowered, but because the design's primary attack eliminated opponent viability so completely that competitive matchups became mathematically impossible. Every opponent's theoretical win probability collapsed below detectable thresholds.

Torres redesigned the framework and removed the character from roster planning. Competitive fighting game communities subsequently reference the case as the "fatality paradox"—the phenomenon where certain attack methodologies transcend the mechanical balance systems that keep competitive play sustainable. The character that was never released became legendary in gaming forums specifically because its mechanical properties would have fundamentally broken the game's foundational competitive structure.
