Aquaman is not immortal. Keep in mind, "immortal" doesn't mean "can't be killed", it means "ages indefinitely". He probably can'\t defeat Wonder Woman. She beat him in A League of One (admittedly, with help from charybdis) and in Flashpoint.
He also retroactively developed a specific weakness akin to Superman's vulnerability to kryptonite or Green Lantern's vulnerability to the color yellow: Aquaman had to come into contact with water at least once per hour or he would die. Prior to this, Aquaman could exist both in and out of water indefinitely.
Is Aquaman a god? Interesting question, you wouldn't necessarily be wrong if you were to think that… But No, he's not. He's half Atlantean and half human.
The Atlanteans have the ability to communicate by telepathy. They seem to age longer than average humans. 300 or 400 years in Human time is just one year to them therefore they live.
Pure-blood Atlanteans have blue skin; most have a lifespan of approximately 150 years. Atlanteans also have access to powerful undersea mutates such as the Behemoth, Megasaur, and the whale-like Giganto and its offspring; such creatures can be made to follow orders with the Horn of Proteus.
The descendants of the Atlanteans according to traditional Theosophy include those of the Mongolian race, the Malayan race, and the American Indian race as well as some people of what in the late 19th and early 20th centuries was called the "olive-skinned" Mediterranean race.
If he goes too long without submerging in water or is dehydrated, Aquaman will weaken and eventually die. While he can stay out of water longer than an Atlantean, he also dehydrates faster than a normal human, so he needs to regularly stay near a water source.
Thor is the far stronger character. I don't see Aquaman surviving Sokovia exploding, or getting punched by Thanos and Hulk, especially since his durability seems to max out at city block level. Aquaman is pretty strong, but Thor is definitely stronger. Aquaman is pretty strong, but Thor is definitely stronger.
Even if Aquaman were to call for aid from a deep-sea monster he can communicate with, Hulk would still win the battle because of his experience fighting alien monsters on other planets. The Hulk's strength and ferocity would make him too powerful for Aquaman to defeat.
Aquaman's 'Talking to Fish' Power Could Let Him Take Down Superman Easily. Aquaman's telepathy doesn't just give him the ability to "talk to" people, it also extends to controlling someone. In many iterations Arthur has taken down his foes by rendering them helpless by simple mind control.
Ocean Master is Aquaman's rival for the throne and always makes a heavy play for it whenever he appears. His strength rivals and oftentimes surpasses Aquaman's own, and his Atlantean powers are more familiar to him as he's known them his entire life, unlike Arthur.
Namor and Aquaman have had instances of immense power in their respective comics, but Namor has the edge. Marvel's King of Atlantis has made Hercules bleed, held his own against the Avengers, and almost destroyed Wakanda with a devastating tidal wave.
In the reality-changing Flashpoint event, the Amazons are at war with the Atlanteans in Western Europe, after Hippolyta was killed by an Amazon disguised as an Atlantean during a wedding between Diana and Aquaman, causing Diana to become the Queen.
Critias talks about an ancient time when the regions of the world were divided between the gods. Atlantis was positioned within Poseidon's domain, where Poseidon fell in love with a mortal girl named Cleito and bore him many children, the first of which was named Atlas, king of the entire island kingdom and the ocean.
The ancient Greeks believed an island empire ruled the sea in the distant past. The lords of Atlantis built a mighty civilization, but their pride eventually angered the gods, who destroyed their island with earthquakes and fire, sending it beneath the sea.
The Bible does not mention the name Atlantis. The closest thing in the Bible was Noah's Flood. Atlantis is a “true” story to the extent that many civilizations have been wiped out by one calamity or another. Floods are incredibly common since most early human settlements would be built right next to the water.
However, Blavatsky's writings mention that the Atlantean were in fact olive-skinned peoples with Mongoloid traits who were the ancestors of modern Native Americans, Mongolians, and Malayans.
Atlanteans are an underwater species of amphibious humanoids that inhabit the Earth's oceans and are native to the kingdom of Atlantis. They are also a sister species of the human race.
