I remember reading the series that lead up to her birth. How much, I don't recall exactly.
Seems her grandfather was miffed his daughter marry an Earthling. He'd kidnapped Moon Maid, who was due anytime, and Junior Tracy wanted his wife and unborn child back. He did up an elaborate disguise, and infiltrated the magnetic ship the governor and Moon Maid were on. The governor wanted his grandchild born on the moon. Legal citizenship status. Junior was discovered about midpoint, and the governor was ready to kill this foul Earthling that despoiled his daughter. It didn't matter that the kids had been married a couple years, already. Just as he's about to end Junior's life, there's a slap and baby crying. It distracts the governor enough that Junior breaks free, and rushes to his wife. In true comic serial tradition, we don't see the baby for two weeks. During that time, the governor has a change of heart and grudgingly accepts his son in law. Honey Moon Tracy was born September 12, 1965, exactly at the halfway point between the Earth and the moon. Hope she never runs for president. Talk about a birther issue. That being the case. She's a Virgo, that IRL, would be 51. Instead, she appears to be in her early 20s and is a private detective in New York City. Her magnetic powers have returned and increased. Those she owes to her mother. Her mother was murdered when a car bomb intend for Dick Tracy, exploded. A toddler, Honey witnessed this.
Dick Tracy was around long before I took my first breath, and I doubt if they'll kill him off before I go, but on that day, the strip will add Jr. To it, and a century later, Honey's step brother will have it with III added.
I suspect Honey will end up in her own strip or comic book.
