First Appearance: May 6th, 1964.
Contact with Earth
By 1964, Moon Valley was technologically far in advance of Earth.The Moon People had harnessed their natural resources to create a thriving society. However, they lacked the heat-resistant metal titanium, which meant that they could not construct durable space-travelling vessels. The Moon People had the ability to receive television signals from Earth, from which they were able to learn many Earth languages including English. They also learned of the industrialist Diet Smith's invention of the magnetic Space Coupe.
The Moon Governor coveted the Space Coupe and devised a plan to obtain it for the people of Moon Valley. He sent his daughter to Earth in an unstable vessel which crashed near the City where Diet Smith and Dick Tracy live. She was discovered by Junior Tracy, who befriended her. This friendship grew into a romance, which made Dick Tracy uneasy. He voiced his disapproval, and Junior responded with defiance.
One night, Junior and Moon Maid borrowed one of Diet Smith's Space Coupes to make a return trip to the moon. Moon Maid showed Junior some of the natural and technological wonders of Moon Valley. The couple were soon followed by Smith and Tracy who, after being briefly imprisoned in an electric cage, were welcomed by the Moon Governor.
The Governor then revealed his scheme. He had sent Moon Maid to Earth with instructions to return with a Space Coupe, and he was very pleased that both Coupes were now in his possession. He re-imprisoned Tracy and Smith, this time with Junior as well. The Governor believed that Moon Maid's affection for Junior was a ruse and he was proud of his clever daughter.
The Governor was soon proven wrong, though, as Moon Maid revealed that she was genuinely in love with Junior. She freed the captive Earthmen and they fled in one of the Space Coupes. Diet Smith left a letter for the Moon Governor, stating his hope that relations could be improved between their people and that trade lines could be established.
Upon returning to Earth, Moon Maid went on a tour of American universities, demonstrating her amazing superhuman abilities. Her relationship with Junior grew closer. She received a telepathic message from her father (through the antenna that were characteristic of their people) informing her that he was coming to Earth in the second Space Coupe that had been left on the moon. Moon Maid feared that the Governor would be hostile and attempt to take her back to the moon.
The Governor had seen the error of his ways and agreed to Diet Smith's trade proposals. He brought gifts of precious gems and moon technology such as the Air Car, which aided law enforcement. He approved of Junior's marriage to Moon Maid, and the two honeymooned on the moon.
The Moon Governor remained wary of his daughter staying on Earth, fearing for her safety in a society that he considered crime-ridden and dangerous. Shortly before the birth of Honeymoon Tracy, the Governor rescued Moon Maid from a murder attempt by Matty Square, taking her back to the moon with him.
Honeymoon Tracy, the first offspring of an Earth Person and a Moon Person, was born shortly thereafter. The Governor was pleased by this development, and he reluctantly agreed let his daughter and granddaughter live on Earth.
End of an Era
Moon Maid was killed in an attempt on Dick Tracy's life. In the aftermath of her death, the Moon Governor severed all ties to Earth, demanding the return of all moon-based technology. He has presumably had little to no contact with his granddaughter in the subsequent years, and Honeymoon has demonstrated less of her superhuman abilities as time has passed.
Years later, a masked vigilante who strongly resembles Moon Maid (and who seems to have many of the same abilities) was sighted in the city. The true nature and origin of this person is unknown. Dick Tracy, Diet Smith and Honeymoon Tracy visited the moon in Smith's remaining Space Coupe, seeking information about this mysterious person, but found Moon Valley to be abandoned. Smith deduced that the Moon People must have constructed their own Space Coupes and left. The fate of the Moon Governor and his people remains to be seen.
