this alternate dimension in the midst of the alternate Aquaman's treaty negotiation with Flash and Shazam. When he discovers that the alternate Aquaman plans to register Atlantis under the Regime (thus giving Superman control over Atlantis), he becomes enraged at his counterpart's willingness to yield and defeats his alternate self as well as the Regime versions of Flash and Shazam before joining Batman's Insurgency to combat Superman. In the game's climax, the alternate Aquaman leads an Atlantean siege on Metropolis by High Councilor Superman's orders before he and the Atlanteans are stopped by the primary Superman and the Amazons. In his single player ending, he unites the world's oceans under the banner of Atlantis and gained a controlling interest in the planet's economy and ecology. The world's multinational corporations hired assassins to end his reign, but the world's citizens rose up in anger to those who would quell Aquaman's influence.

They arrive in Kahndaq and are attacked by Grodd, who fights the two kings alongside the brainwashed Green Arrow, Black Canary, and Blue Beetle. Aquaman kills Grodd to avenge the Atlanteans abducted by Brainiac before he and Black Adam successfully lower Brainiac's defenses. On Brainiac's ship, Arthur is pleased to find out that Superman managed to restore Atlantis from Brainac's ship. In Batman and Superman's conflict over whether to spare Brainiac, he sides with Superman as he believes leaving Brainiac alive would be too risky and is fine with killing his enemies as it matches Atlantis' old fashioned sense of justice. He is defeated by Batman on the ship, as Batman puts Arthur out of commission by stabbing his leg with the Atlantean Trident. In his single player ending, Superman rises
