Arthur learns so well as a child because he can instantly adapt to the environment and learn to control it and use it to his own benefit. He’s thrilled to plunge into the sea, into potentially dangerous situations, and emerge unscathed. He’s also adept as an adult at seeing the potential in the environment and using it – such as snatching up a fallen porthole and using it to shield him from a hail of bullets. When trying to figure out a riddle, Arthur does not try to reason it out in his head – he looks at the environment and realizes the bottle fits neatly into the hand of a specific statue, which gives them a view of “their destination.” Arthur also leaps into things without thinking about them fully, confidently insisting on challenging his half-brother to a dangerous fight, despite knowing nothing about the rules. In Justice League, Arthur divides his time between joyriding in the ocean, saving people who need saving, and avoiding his responsibilities under the sea. Arthur adapts to any situation and uses the most logical way out – often relying more on his senses and instincts than ruthless logic. But he can point out the obvious when it counts and his lack of over-thinking helps them solve the riddle quicker. Once he commits to something, he wants to get it done quickly and efficiently and to move on. He is somewhat unconcerned with the ethics behind others’ decisions, except when they hurt people. Arthur reasons that he can leave someone to die, because he’s a pirate who has killed innocent people – not realizing in the process that he is creating a powerful enemy, due to his own inability to understand their emotional attachment to their father. He doesn’t feel particularly obligated to the masses and it takes him a while to recognize his responsibility toward them by involving himself in the League. He also carries around and refuses to talk about a lot of his self-blame and self-loathing for his role in his mother’s fate, while refusing to get involved in the war until it directly impacts his father. His ability to see the consequences of his decisions is poor – he rarely suspects betrayal, and he feels doubtful about bringing back Superman. He second-guesses this seconds away from them resurrecting him, and insists they stop. Arthur is wrong – Superman gives them a fight off the bat, but turns around and helps them defeat their enemy and save the planet.

Arthur is a hard-headed and stubborn man who initially tells Bruce Wayne to get lost, he has no interest in joining his merry little band of heroes. He spends a lot of his free time getting drunk, he has a quick temper, and immediately leaps into any fight. He takes challenges to his authority as personal affronts and asserts himself, sometimes not thinking about the consequences of his involvement or how it might cause friction. He is over-confident and cocky, but also aware of power dynamics – he isn’t sure bringing back Superman is a good idea because of the severe imbalance of power between them all. He sees piracy as vile, because of how many innocent people it kills, which makes him lay down a hard line for criminals. He offers them no mercy, creating his own rival / adversary in the first place (which leads to violent combat between them). Arthur doesn’t check the morality of his decisions or show compassion for fallen adversaries; he leaves a pirate to drown to death or be killed in an explosion. He’s also running away from his responsibilities. He “should” be the rightful king of Atlantis, but that sounds like too much work. It sounds like commitment. Arthur wants to get in there, do some good, get out, and go have a beer with his dad. That’s it.
