As Aquaman is meant to connect to the DCAU, he has the same personality as that counterpart.
Aquaman has super strength and has skin tougher than a rhino's. As an Atlantian, he can also breathe underwater and telepathically communicate with undersea life. His harpoon hand can also be used as a melee weapon as well as a grapple.
Aquaman's key weaknesses are his ego and his family and kingdom being put in danger.
Aquaman attended Bizarro's funeral and placed a rose on his tomb.
