Personality and Traits
In contrast to the heroic regular Aquaman, Regime Aquaman was a callous and irritable individual who had nothing but contempt for his counterpart, a feeling that was quite mutual. Though he essentially yielded to the Regime in full, Regime Aquaman maintained that such actions were necessary for the good of Atlantis, showing that he was well-intentioned in spite of his villainy.
Regime Aquaman also displayed some xenophobic tendencies, as one of his generic clash-quotes in-game is "Surface World scum!" Ironically, between his now being a poor ruler of Atlantis and bigoted towards surface-dwellers, this version of Aquaman has much in common with Aquaman's villainous brother and enemy Ocean Master.
The reason behind his downfall was because Superman blackmailed Aquaman in the first place, such as threatening Aquaman that Superman will destroy Atlantis if Aquaman opposes Superman, and Aquaman himself is forced into evil. Once Superman is defeated, Aquaman is finally freed while still traumatized with his villainous action when he was a Regime member, and decide not to be involved with surface-dwellers’ conflicts. However, Brainiac’s invasion drags Aquaman into involving with the surface war, at cost of loosing Atlantis onto Brainiac’s hand for ignoring Batman’s advices no matter which side Aquaman is in, either Regime, Insurgency or neutral. After Brainiac's defeat and the conflict between Batman's Insurgency and Superman's Regime started again, Aquaman, despite not being a Regime member anymore, can be sometimes agree with Superman's opinion if anything that is most dangerous as Brainiac must be eliminated permanently, but may unintentionally led the Regime took over Atlantis again. In his arcade ending, connected to Bad/Superman Story Ending, Aquaman regain his circle of trust towards some surface dwellers, as shown when he seeks his counterpart’s help to defeat his world’s Superman once more like Batman did.
