History NightmareFuel / AquamanAndTheLostKingdom

* Black Manta's rage and hatred of Aquaman makes him a dreaded foe, and he vows to destroy everything Arthur cares about: his home, his kingdom, his family. He doesn't care what he has to do to enable it, whether it's [[WouldHurtAChild killing children]] or ''ravaging the world itself''.

* Black Manta plans to release Kordax with the blood of the Atlantean royal family. Orm assumes he's coming after himself and Arthur, but Arthur reveals that they're not the last in their bloodline - his son is, and Black Manta has kidnapped him! This is a homage to the comics when Manta murdered Aquaman's son, an event that affected the hero for decades. Thankfully the film averts this, with the baby eventually rescued.
* Kordax is Atlan's brother who ruled over Necrus, but the continued use of oricalchum began to affect his mind, also causing the global temperature to rise and endanger the world. Kordax for his part was driven mad and became paranoid towards his brother, later transforming his people into horrific tentacled zombie creatures. Kordax's final appearance is some kind of lich king - he's been corrupted so much by oricalchum, he's become inhuman.
* Kordax's trident enables him to possess anyone who wields it... but the members of his bloodline are the most vulnerable.
* Kordax's kingdom is a dark industrial site filled with monsters that are poisoned beyond recovery.
