Deep Sea King's Army

Lore & Background

The Deep Sea King, having evolved far beyond normal biological limits, possesses immense intelligence and a desire for absolute dominance. Recognizing that individual monsters are easily dispatched by heroes, he orchestrated the gathering of thousands of sea-dwelling mutants into a unified military force. This army is not merely a horde; it operates with tactical precision, utilizing specific units to overwhelm defenses, target key infrastructure, and isolate powerful opponents. The invasion begins with the destruction of coastal cities, forcing the Hero Association to mobilize its strongest assets. The Deep Sea King's strategy relies on sheer numbers and specialized abilities that counter standard hero tactics. However, despite their overwhelming force, the army ultimately crumbles when faced with the absolute power of S-Class heroes, particularly the arrival of Saitama. Their defeat serves as a grim reminder that while evolution can create powerful armies, it cannot bridge the gap between mortal ambition and true omnipotence.

In Their Own Story

The water turned black as the horizon vanished beneath a wall of churning foam. From the depths rose the Deep Sea King's command, a silent order transmitted through the minds of thousands. Leviathans with eyes like burning coals surged forward, their scales scraping against the hulls of sinking ships. The air smelled of salt and rotting flesh as the first wave crashed onto the beach, not to swim, but to march. Heroes stood ready on the pier, fists clenched, but the sheer density of the enemy made every step a gamble for survival. In the distance, the King watched from his throne of coral and bone, waiting for the surface world to break.

The hierarchy of this faction is strictly top-down, with the Deep Sea King serving as the sole commander and strategic mastermind. Below him lie various elite commanders, including the Four Devas, who lead specialized divisions capable of independent tactical operations. Their primary ideology centers on the belief that sea life has evolved to a higher state than humanity, granting them the right to rule the planet. They view humans as obsolete obstacles that must be removed or enslaved to secure their new world order. Key members include the Four Devas (such as the Great King of Beasts and the Sea Emperor), who act as the vanguard, alongside countless lesser mutants serving as cannon fodder. Their impact on the global balance was severe, nearly collapsing the Hero Association's defense grid and forcing a merger of all S-Class resources to contain the threat.
