Knowledge is a heavy burden, but foreknowledge is a curse.
As Sunshine grew into her toddler body, her motor skills sharpening and her vocabulary expanding (though she carefully maintained a facade of age-appropriate babbling around the staff), the looming reality of her existence within a crossover universe began to press down on her with suffocating weight.
She knew about the Addams family's dark, violent history. She knew they were creatures of gothic romance, surviving assassination attempts, angry mobs, and literal curses through sheer, macabre resilience. But she also knew the other half of the equation. She knew about Hogwarts. She knew about Albus Dumbledore, Voldemort, the Death Eaters, and the impending, catastrophic wizarding wars that would soon drench Britain in blood.
The timeline was a constant, ticking clock in the back of her adult mind. By her calculations, the First Wizarding War was either reaching its peak or drawing to a close across the Atlantic. Harry Potter was likely a toddler right now, just like her, destined for a life of manipulation, abuse, and warfare orchestrated by a supposedly "Light" wizard.
Sunshine had absolutely no intention of participating in that narrative.
She had spent six decades being a victim, a pawn moved across the board by cruel, controlling forces. She refused to be dragged into a magical war led by an old man who operated on the philosophy of the "greater good"—a philosophy she recognized all too well from the bureaucratic, government systems that had failed her in her previous life.
Her strategy was simple: she would be a Squib.
Or, at the very least, she would repress her magical core so thoroughly, so completely, that the Quill of Acceptance at Hogwarts would never register her existence. She would stay in America. She would stay in the damp, glorious safety of the Addams manor, studying poisons with Morticia and avoiding Gomez's swinging broadswords.
But magic, much like trauma, demands to be felt. It cannot be buried alive without severe consequences.
The magical core within her was not a gentle, whimsical force. It was a potent, volatile mixture. Half of it was the standard, structured magic of the Harry Potter universe, capable of wandwork and incantations. But the other half was pure Addams. It was ancient, blood-deep, and intrinsically tied to the macabre. The Addamses were not merely wizards; they possessed a "dark affinity," a natural, biological attunement to shadows, decay, and the chaotic energies of the earth. It was why they had been run out of Britain centuries ago by the puritanical Light wizards. They were too strange, too morbid, and too fundamentally dark to be controlled.
For months, Sunshine had successfully wrestled her magic into submission. Whenever she felt the telltale prickle of energy behind her eyes—usually when she was frustrated by a heavy door she couldn't open or a book she couldn't reach—she would mentally slam a heavy iron door down on the sensation. She forced the magic deep into her gut, locking it away.
But a toddler's body is a fragile, impulsive vessel. The emotional regulation of a sixty-year-old mind can only do so much when the physical host is exhausted, hungry, and currently being thwarted by a haunted architectural feature.
It happened on a stormy evening in late October. The manor was particularly restless. The suits of armor were clanking their halberds, and the portraits of deceased relatives were gossiping loudly in the corridors.
Sunshine had managed to evade Lurch and was on a mission. She had seen Gomez place a heavy, fascinating-looking object—a purportedly cursed Aztec puzzle box—on the top shelf of a bookcase in the second-floor gallery. She wanted it. It was cold, it was raining, and she was bored.
She waddled down the long, shadowed hallway, her golden curls bouncing, her tiny black boots slapping against the stone. She reached the entrance to the gallery, only to find her path blocked.
The manor possessed several defense mechanisms, one of which was a large, animated stone gargoyle that usually perched on the roof. Today, seeking refuge from the torrential rain, it had climbed through a window and stationed itself directly in the doorway of the gallery.
The gargoyle was the size of a large mastiff, carved from black basalt, with wicked, curling horns and glowing, ember-like eyes. It looked down at the golden-haired toddler and let out a low, grinding growl that sounded like boulders crushing together.
Sunshine stopped. She crossed her chubby arms over her chest.
"Move," she commanded, her voice high and piping, lacking any real intimidation.
The gargoyle snorted, a puff of gray dust billowing from its stone nostrils. It shifted its massive weight, completely blocking the doorway, and settled down on its haunches, looking exceptionally smug.
In her past life, an obstacle like this—a roadblock placed by a larger, more powerful force—would have induced immediate surrender. She would have dropped her gaze, turned around, and accepted defeat. It was the trained response of a battered woman.
But she was tired. The air pressure from the storm was making her ears pop, her teething gums ached, and she really, really wanted to look at that puzzle box. A sudden, violent surge of irritation flared in her chest. It was a potent, foreign emotion. It wasn't fear; it was pure, unadulterated rage.
I survived sixty years of hell, she thought, her tiny hands balling into fists. I died violently. I endured the agony of rebirth. I am not being stopped by a piece of sentient landscaping!
She pushed forward, attempting to squeeze past the gargoyle's heavy stone wing.
The creature barked—a harsh, grating sound—and shoved her backward with a flick of its heavy tail. Sunshine stumbled, her rubbery toddler legs giving out, and she fell hard onto her backside on the cold stone floor.
The physical jolt shattered her mental iron door.
The magical core she had spent months suppressing erupted. But it did not manifest as a burst of accidental, colorful sparks. It did not levitate her, nor did it banish the gargoyle.
It manifested as the Addams dark affinity.
The air in the hallway instantly plummeted by twenty degrees. Sunshine's breath plumed in the sudden, freezing air. The flickering candles in the wall sconces did not blow out; they turned a sickly, bruised shade of purple, casting long, monstrous shadows across the walls.
And then, the shadows began to move.
Sunshine didn't realize she was doing it. She was simply glaring at the gargoyle with all the accumulated fury of a woman who had been pushed around for an entire lifetime. From the hem of her black velvet dress, the shadows on the floor deepened, thickening like spilled ink. They slithered forward, creeping up the stone base of the gargoyle.
The creature stopped looking smug. Its ember eyes widened in genuine panic. It tried to stand, to scramble backward away from the golden-haired child, but the shadows were already wrapping around its heavy basalt legs, freezing them in place.
Sunshine felt a cold, exhilarating rush of power course through her tiny veins. It didn't feel like the structured, wand-waving magic she had read about in Harry Potter. It felt like commanding the very rot of the earth. She pointed a trembling, chubby finger at the gargoyle.
A wave of pure, dark intent rolled off her. Where the shadows touched the gargoyle, the ancient stone began to hiss and pit. It was not destroying the creature; it was forcefully aging it, inducing a rapid, magical erosion.
The gargoyle let out a whimpering, grinding squeal, utterly terrified of the pitch-black aura suffocating it, emanating from a child who looked like a literal sunbeam.
"Fascinating."
The voice broke her concentration. The shadows instantly snapped back to normal. The purple flames reverted to orange. The temperature stabilized. The gargoyle, freed from the magical pressure, scrambled backward with terrifying speed, abandoning the doorway and fleeing down the hall, leaving a trail of dusty paw prints.
Sunshine sat on the floor, panting, feeling incredibly drained and deeply panicked. No, no, no. I used it. I showed my core. The British Ministry will know. Hogwarts will know.
She looked up.
Gomez and Morticia were standing at the other end of the hallway. They had witnessed the entire display.
Sunshine braced herself. In the wizarding world, a child displaying such dark, oppressive magic would be feared. They would be taken to St. Mungo's, or monitored by the Ministry for dark tendencies. She had failed her mission to remain hidden.
Gomez walked slowly down the hall, his eyes wide, his cigar forgotten in his hand. He stopped in front of her, staring at the spot where the gargoyle had just been magically eroded.
He dropped to his knees. He looked at Morticia, who had glided up beside him, her hands pressed to her chest in an attitude of profound, reverent shock.
"Did you see it, Tish?" Gomez whispered, his voice trembling with an emotion so intense it bordered on religious ecstasy. "The temperature drop... the manipulation of the void... the sheer, oppressive malice?"
"I saw it, mon cher," Morticia breathed, staring down at her daughter as if she were looking at a masterpiece of classical art. "Her magical signature... it is magnificent. I have not felt an aura that bleak, that deeply steeped in the macabre, since Grandmama's mother."
Gomez scooped Sunshine off the floor, holding her up to the ceiling as if offering her to the dark gods of the manor.
"She is a prodigy of the dark arts!" Gomez bellowed, his voice echoing triumphantly through the halls. "Look at her, Tish! Cursed with the face of a cherub, burdened with hair like spun gold, but possessing a magical core as black and rotten as a centuries-old crypt! The Addams legacy is secure!"
Sunshine slumped in his grip, exhaustion overtaking her tiny body. Her plan to be a Squib was utterly ruined. Her magic was too potent, too violently tied to her emotions, to remain hidden forever. The Hogwarts letter would eventually come.
But as Gomez spun her around, laughing maniacally, and Morticia looked on with a serene, terrifying pride, the sixty-year-old soul felt a twisted spark of grim satisfaction.
If fate was going to drag her into the British wizarding world, she would not be going as a helpless victim, nor as a pawn for the Light. She was Sunshine Addams. And she had just discovered that her bite was far, far worse than her agonizingly cheerful bark.
