Everyone knows the legend of Sonic the Hedgehog and his friends—the heroes who saved Mobius again and again. After their final great war, they vanished from the spotlight. Twenty years passed, and Mobius wondered where its heroes had gone. Now in their early to mid-thirties, the legends live quieter lives—still powerful, still vigilant, but anchored by family.

Sonic, 35, laughs more than he used to. He and Sally Acorn, long divorced, co-parent their sharp-tongued, fearless daughter Sonia (13). Their marriage ended bitterly, and Sally no longer hides her disdain for him—but they remain bound by responsibility, if not respect.

Years later, Sonic and Amy Rose had Rayna (11): bright, stubborn, fast, and spoiled. Amy insists Sonic abandon heroics entirely—be a husband, be a father, be present. She has already forbidden him from seeing Amaya, even in casual gatherings.

Nearby, Knuckles and his wife Scarlet keep watch as their son Luke (12) arm-wrestles Boulder (10), Mighty’s impossibly strong kid. Rouge lounges nearby, tracking her snack-stealing daughter Roxanne (6).

Tails and Tanya tinker with tech while baby Milo pulls at Tails’s tails. Cream rocks three-month-old Jack as Vanilla watches proudly.

Blaze supervises as Nymph (7) controls fire, while Silver kneels beside Sia and their son Lune (11), pebbles orbiting in neat lines.

Jet, Wave, Storm, Whisper, Tangle, Big, Honey, Marine, Espio, Charmy, and Vector round out the chaos—until the air shifts.

Shadow arrives with his wife Annabelle and their twin sons Aaron and Shane (12) and Daughter Maria (6).

And alongside him is Amaya.

Between them, hood low, stands a boy no one knows.

Nicholas.

Twelve years old.

Hidden for twelve years.

A faint crimson Chaos pulse flickers beneath his hood. Milo stares. Nicholas instinctively moves closer to Amaya, gripping her jacket strap. If Sonic saw his face— Across the clearing, Sonic laughs as the kids train. Sonia barks orders at Rayna. Luke shields Roxanne. Nicholas watches silently.

Kids who hate him already—though they don’t know why.

Then Sally arrives. She stops cold.

A breeze lifts Nicholas’s hood.

Indigo fur. Crimson streaks. Eyes too familiar.

Silence crashes down. Amy stiffens, anger flaring. Sonia and Rayna scowl instantly.

Sonic steps forward, Chaos energy humming.

“…Why,” he asks softly, “do you feel like me?”

Nicholas panics. His quills spark red and blue. Amaya reaches for him—but— “Why does that child look exactly like Sonic?” Sally snaps.

Shadow moves between them, immovable.

Sonic kneels anyway, voice trembling. “Hey… it’s okay. What’s your name?”

“…Nicholas.”

Sonic looks up at Amaya. “Please. Tell me the truth.”

She exhales. “Twelve years ago, I found him in one of Eggman’s abandoned labs. He wasn’t born—he was made. From your DNA. And mine.”

Shock ripples outward.

“He was meant to be a weapon,” she continues. “I took him and ran. You had Sonia. Then Rayna. You were finally happy.”

Sonic’s eyes burn. “You thought I wouldn’t want him?”

“I thought the world would destroy you both.”

Jules and Bernadette step forward, stunned. A grandson.

Sally turns away, furious. Amy grips her hammer, seething. Sonia and Rayna glare openly at Nicholas.

But Sonic doesn’t look away. He gently places a hand over Nicholas’s racing Chaos aura.

“Hey,” he says, smiling through tears. “I’m Sonic.” Nicholas whispers, “…I know.”

And for the first time in twelve years— Sonic the Hedgehog meets his son.
