A few years later, they were on Earth. Kandor was on a quest to locate the Golden Eels and acquire their powers. He had taken to using mind-control to keep the bored Hila by his side. He had her set-up a trap for Aquaman, intending to interrogate him for the location of the Eels. Hila received some affection from Aquaman before Mera caught them in the act. Then she lured him to a confrontation with Kandor. Actually Hila had planned for the two men to knock each other out, leaving her free.

Hila arrived on Atlantis and impersonated Mera. But acts of public adoration for the Queen by the Atlanteans, including a birthday celebration, got her feeling guilty. She tearfully admitted the truth and returned to rescue Arthur. Kandor had gained the upper hand in the battle and was ready to literally crush his opponent. When Hila rescued her brother-in-law and confronted her lover. The two fought using their hard-water powers.

Meanwhile Professor Xeron/Kreon contacted Mera and restored her lost powers. The second sister joined the Fray. But the general confusion allowed Kandor to place one of the sisters under his mind-control again. Aquaman was then in a new predicament. The two identical sisters were fighting over his fate, one trying to kill him and the other to save him. The mind-controlled one lost the fight.

Kandor was worried his Hila was hurt. Only to learn he had made the same mistake Arthur did. He was unable to tell them apart. Mera was the sister first mind-controlled and then defeated. Hila was the defender of Aquaman and the victor. The four of them then had to join forces against the Armadillo Men. created by Kandor to be his private army, the genetic constructs had rebelled. The two sisters and their respective consorts were able to defeat them.

A tired but healthy Kandor released Mera and expressed his love of Mera. Then the four were joined by Aqualad. He had used the contact with Dimension Aqua to ask some questions.

The other members of their race were simply unable to locate them and recall them. The duo returned home but their subsequent activities are unknown.
