The Anglerfish was born in Feral City, left when she was still very young, spent a couple of decades making a small fortune as an interdimensional space pirate and investing her loot in Feral City real estate, decided she was getting too old for piracy, came back to Feral City, parked her anglerfish-shaped pirate ship on the roof of one of her buildings, turned the building into a dance club, and became one of Feral City's major crime bosses and vice purveyors.
Now she hangs out and runs her empire from her old captain's chair on the bridge of her ship, overlooking her dance club, wearing comfortable leggings and sandals, attended and guarded by her loyal crew, and everyone addresses her as "Madame."
The Anglerfish is a woman who knows how to live.
