Mera

Queen Mera is Aquaman's wife, and thus queen of Earth's oceans. She is also known to run the Conservatory of Sorcery in Atlantis, and seen as its combat sorcery teacher.

History
The exact details about Mera's history are currently unknown. However, at some point in she met and married King Orin, also known as Aquaman, and became the Queen of Atlantis. At some point over the years, she became very gifted in Atlantean sorcery and took administrative and teaching control of Conservatory of Sorcery in Atlantis, and seen as its combat sorcery teacher. Amongst her students were Aqualad, Garth and Tula.

Eventually after Aqualad (Kaldur'ahm) and Garth helped Aquaman defeat the Ocean Master, Aqualad left Mera's studies to become Aquaman's sidekick. Still, he maintained a close familiar relationship with Mera, who showed great joy at seeing Aqualad return after several months away. That night at dinner, she informed Aqualad, Tula and her brother-in-law Prince Orm that she and Aquaman were expecting their first child.

The festivities however were cut short that night as Atlantis was attacked by Black Manta. Despite her pregnancy and the pleas of her subjects to get to safety for the sake of herself and the child, Queen Mera helped in defending her people, with her impressive magical and water manipulating abilities.

She later thanked the efforts of Aqualad and Garth for their help in the defense of Atlantis.
