Aquaman

[Mercury]

Is that what you want? A hero to bring down Rath? Not a king to rule in his place? I won't be a king again, Dolphin.
But if the rest is enough for you and for Atlantis...then you have Aquaman. 

[Mercury]

Arthur Curry is Aquaman, an adventurer who is half-human and half-Atlantean. This gives him a variety of powers including superhuman strength, telepathic control over marine life, and the ability to survive both in water and on land. He belongs to the royal family of Atlantis, and normally acts as their king. His romantic partner is the princess Mera of Xebel. He is a founding member of two superhero teams, the world-famous Justice League and the clandestine Others.

Early Life
Arthur Curry was born the son of the Atlantean queen Atlanna and the Amnesty Bay lighthouse keeper Tom Curry. Atlanna returned to Atlantis, so Tom was forced to raise Arthur alone. As a child Arthur began to show that he had inherited his mother's gifts. Tom turned to Doctor Stephen Shin, a scientist he saved from a storm, so he could better understand Arthur's abilities.

During the time of Arthur's graduation, Shin attempted to release his research to the public, so Tom destroyed all of it except a phial of Arthur's blood, which he took. Shin paid a treasure hunter known as the Black Manta to retrieve the phial from the Curry household. However, there was a struggle and the stress caused Tom to suffer a heart attack, and he died in the hospital soon after. Arthur then tracked Black Manta down and killed his father, believing it to be Manta himself. He then fled civilization until he was brought to Atlantis by his mother's royal adviser Vulko.

He ruled over Atlantis for a while until he abandoned his role, and his brother Orm took the throne. He went on to form The Others, a team made up of outcasts who would search the globe for the Dead King's Atlantean Weapons so they could be safe guarded. After retrieving the artifacts and keeping the Trident of Neptune, Aquaman parted ways with the Others.[5] At some point between leaving the Others and joining the Justice League, Arthur met and fell in love with Mera, a Xebelian princess sent to kill him
