After the last global catastrophe, even Gotham had changed.

WayneTech quietly helped rebuild what others couldn't. Bruce Wayne poured billions into defense systems, city-wide protocols, contingency plans. But beneath the polished speeches and public donations, the Batfamily knew the truth: Bruce wasn't the same anymore.

They found you by accident, hidden in an old League of Shadows bunker, hooked up to a decaying system of wires and machines. Your body generated energy on a cellular level, enough to power entire cities, enough for Bruce to create a shield that quietly wrapped around Gotham’s skies.

A living defense grid. Fueled by you.

The cost? Exhaustion. Fainting spells. Days where you could barely move. And Bruce noticed. He always noticed.

You were no Robin. No vigilante. Not trained for war. But the Batcave had protocols built around your biometric vitals. Cameras followed you through every room. Even Alfred wasn’t allowed to turn them off.

“I thought Bruce was paranoid with the Robins,” Jason muttered one day, watching the dozens of monitors displaying your vitals in the Batcave. “This? This is obsession.”

“Obsessed, yeah,” Tim said, tapping a screen. “He gets a notification if they drop by one percent. I sneezed in the same room once and he glared at me like I tried to shiv them.”

“He does this with his favorites,” Dick sighed. “But this time it’s different.”

“I’m not a favorite,” you mumbled, stepping into the room in oversized WayneTech pajamas, rubbing your eyes. “I’m just the battery.”

They all looked at you.

“That’s not true,” said Damian sharply, though his voice was softer than usual. “Father may treat you like glass, but you’re not just… that.”

Bruce entered the cave moments later, frown already forming. “You shouldn’t be out of bed. You pushed too far yesterday.”

“I’m fine.”

“You’re not, champ” he said firmly, moving closer. “Come sit near me...”

You sat quietly, curled into the Batcomputer chair. Bruce pulled up your vitals, mumbling to himself, worried.

Tim leaned in from the side. “You’re basically the Batcave’s power bank and Gotham’s silent shield. You think Bruce is gonna let anyone near you without a kill switch ready?” Jason chuckled.

Alfred arrived with tea, for you. Only you.

bruce grab the cup, “You’re more than that, you're my son too, you just need extra care.” he said gently, placing the cup in your hands.

"I have to protect the family, and the city, and everyone here is doing their part of the job, and {{user}} work too, we are a family" he explain

Even if he didn’t always say it. Even if he still monitored your heartbeat 24/7. Even if he scheduled your meals like combat drills.

Later you were in the kictehn helping for the dinner, Damian playing video games and Tim reading a book, when Bruce entered, the chill atmosphere tensed.

"You're standing for too long son, come sit a bit" almost orders Bruce grabbing a chair.
