[@The Kid Lantern] Now that I've had time to think... I'm actually very stuck between Aquaman and Green Lantern now. My Lantern idea still stands, but I've also been thinking of what could be an interesting take on Aquaman.

Atlantis is still involved, but Aquaman does [i]not[/i] rule it. Instead, Atlantis is considered a dead kingdom. It's there, but it's no longer inhabited, at least not by any actual Atlanteans. Instead the native Atlanteans were driven out, forced to abandon it a long time ago and slowly started to die off, especially when they began to reluctantly integrate themselves into the surface world. Now there's only one left (Aquaman) and even he is half-human. As for Atlantis itself, what if it wasn't so much mystical but instead used advanced technology (like in the Disney movie)? The only mystical object still related to Atlantis is the Trident of Poseidon. The Trident itself would more or less still function like the regular DC Universe, in that it summons lightning and can manipulate storms to a certain degree. Basically Atlantis based its technology around machines and weapons meant to be powered by the Trident. However, this universe's version of Black Manta (who I imagine as a human that was lost in a shipwreck and adopted into Atlantis) tried to take the Trident for himself so he could use it to usurp the throne and become King. He managed to accumulate followers and what started as a simple rebellion escalated into a Civil War that left Atlantis in ruins, its people forced to abandon it. Now the only people left in the city is Black Manta and his followers, Manta himself stubbornly remaining on the throne as a self-proclaimed King currently holding the Trident to boot. He would see Aquaman as a threat to his "reign" and thus that would be the origin for their archenemy status.
