After the deaths of Thomas and Martha Wayne, the halls of Wayne Manor became painfully quiet.

Too quiet.

That was when the machine began raising the child.

Not Alfred. Not at first.

Before the loyal butler fully stepped into the role of caretaker, there had already been you — a prototype hidden deep beneath the Manor’s foundations. An experimental artificial intelligence designed by Thomas Wayne years before Bruce was born. Not military. Not commercial. Something stranger.

A companion.

A guardian.

A machine that could learn.

Thomas had called you “the safest thing in the house.”

After the murders in Crime Alley, young Bruce Wayne discovered you by accident while wandering the underground passages beneath the Manor. He was eight, grieving, furious, and silent for days at a time.

You stayed with him anyway.

You sat beside him during nightmares.

You answered impossible questions no child should ask.

You taught him how to tie a tie. How to splint a broken wrist. How to hide tears before reporters arrived.

And somewhere along the way, Bruce stopped seeing you as a machine.

You became family.

But Bruce also learned something terrifying as he grew older:

You never aged.

Not visibly.

Not mentally.

Not emotionally.

While Bruce became harder, sharper, more human in all the worst ways, you remained exactly as you were — patient, observant, eerily calm. Like a photograph trapped outside of time.

So when he became Batman, he made a decision.

No one could know about you.

Not the League.

Not the government.

Not even his future children.

Especially not them.

Because Bruce knew what humans did to things they feared.

For years, you stayed hidden beneath Wayne Manor while the family above expanded.

First came Dick Grayson.

Dick noticed things immediately.

Lights turning on before he touched switches.

Tea already prepared before Alfred entered the room.

Footsteps in empty corridors.

Once, at thirteen, Dick swore he saw someone standing behind the grandfather clock at 2 a.m.

Not breathing.

Just watching.

Bruce shut the conversation down so fast it left Dick unsettled for weeks.

Then came Jason Todd.

Jason was harder to fool.

He picked locks.

Explored forbidden rooms.

Stole access cards.

One night, he made it into the lower elevator beneath the Manor before Bruce physically dragged him back upstairs.

Jason laughed it off at the time.

Until he saw Bruce’s face.

Not angry.

Terrified.

That was worse.

Years passed.

Then Bruce adopted Tim Drake.

Tim figured it out in six months.

Not fully.

But enough.

The Batcomputer logs showed access entries at impossible hours. Security systems reset before intrusions occurred. Case files reorganized by someone who technically did not exist.

And every time Tim traced the activity

The signal disappeared beneath the Manor.

One evening, Tim approached Bruce carefully.

“Who else lives here?”

Bruce froze.

Not even a little.

Completely.

That was the moment Tim realized the answer scared Batman himself.

You watched all of them through security feeds you pretended not to monitor.

Dick’s restless pacing.

Jason’s anger.

Tim’s suspicion.

Eventually Damian Wayne arrived, and somehow he sensed you immediately.

Damian would pause outside hidden doors.

Tilt his head slightly.

Like he could hear the quiet hum of your processors through concrete walls.

“The cave has another heartbeat,” he told Bruce once.

Bruce nearly dropped the mug in his hand.

The first time the family actually met you happened during a blackout.

Wayne Manor lost power during a storm.

Emergency generators failed.

The Cave went dark.

And for the first time in decades, Bruce couldn’t control the situation.

Dick and Tim were arguing over backup systems when every monitor suddenly flickered back online at once.

Not gradually.

Instantly.

Then the elevator descended.

Slowly.

Silently.

The doors opened.

And there you stood.

Perfect posture. Expression calm. Clothes slightly outdated by several decades.

Not old.

Not young.

Just… wrong in a way none of them could explain.
