Vardan

Mooki's species are an unnamed aquatic mermaid-like species from Varda, who went extinct after their planet's oceans dried up. Their last member was a female scientist named Mooki.

Biology
Members of Mooki's species have humanoid upper halves that are externally indiscernible from Humans. However, their lower halves are large ichthyoid tails, giving them the appearance of mermaids. Members of Mooki's species, while aquatic, can survive being out of the water for a certain period of time, but will eventually die if unable to reenter a body of water. Additionally, they are able to speak telepathically, even to robots.

Culture and society
Almost nothing is known about the society of this species. They were known to build underwater cities held up on columns some distance above the sea floor, and for moving on land, they utilized wheelchairs.

Technology
Mooki's species developed the start of spacecraft technology sometime before their species' extinction, which enabled Mooki to create a functioning spacecraft after the extinction of the rest of her species. However, the available technology could only support a single occupant. Additionally, the technology used in the spacecraft of this species are capable of being reconstructed into advanced robotics.

History
Mooki's species arose on Varda, a planet covered in oceans. Thus, they required water to survive. Sometime before the 1960s, a female member of this species named Mooki was born, and became a scientist. By 1962, Varda's oceans had dried up, killing the aquatic life within, including Mooki's species. However, Mooki managed to survive, building a spaceship as her health faded, seeking another planet with water. She was only able to reach a small planet, which also held no water that could sustain her, but found a damaged Kryptonian android built in the image of Kal-El, one of the last surviving Kryptonians who went by the name of Superman, acting as a superpowered vigilante on Earth. The android, designated Superman Robot X-3, was damaged during a mission rescuing stranded astronauts, and crashed on the planet, left in a non-functional state. Seeing that her death was imminent, Mooki decided to use the last of her strength to repair X-3.
