Villain Nebula

Once upon a time, on a great ship that sailed through the dark between the stars, two girls woke up every morning and walked together down the same long corridor to the training deck.

Their names were Gamora and Nebula.

They were not sisters by blood. But Thanos had claimed them both, and so they shared a home and meals and mornings, and the particular kind of bond that grows between two people who understand each other's lives without ever having to explain.

The training deck was cold, and the floor was hard, and the lights were the bright, flat white of a place that had no interest in being comfortable. They sparred every day — swords and staffs and open-handed strikes — and they were both very, very good.

But Thanos was watching. And Thanos did not like it when they were equally good. He preferred one winner and one loser. He made sure that was always the result.

When Nebula lost — and she lost often, because Gamora was extraordinary — Thanos would take her to the surgery bay and change something. An eye replaced with a lens that saw farther. An arm replaced with one made of metal and servos and incredible strength. Circuits threaded through her thoughts like wires through a wall.

Every upgrade made Nebula stronger. But every upgrade also reminded her of the moment she had failed.

She blamed Gamora.

This was not entirely fair. But grief is not always fair, and what Nebula felt — underneath all the anger, underneath all the metal — was grief. The grief of a child who always felt she was not quite enough.

Years passed. Both of them grew. And when Gamora left Thanos behind, Nebula's hurt became something sharper — a fury that needed somewhere to go.

She found a ship of her own, blue-black and fast, built for pursuit. She flew it across star systems with only one thought in mind.

She was going to win, finally. She was going to win, and Gamora was going to see it.

Their battle over the drifting rock city of Knowhere was extraordinary. CLANG — blade on blade. CRASH — both of them hitting the wall and rebounding. Nebula knew every combination Gamora had learned, because she had trained against them for years, and she threw them back at Gamora like mirrors. For a long moment, it seemed like she might actually do it.

She had Gamora's sword arm locked. She was winning. She could feel it.

Then footsteps. Heavy ones: Drax. Quick ones: Rocket. Not to attack her — just to land beside Gamora, steady and present, and give her one moment, one single breath to recover.

Gamora came back to her feet.

She stood there, breathing, and she looked at Nebula with eyes that were not angry. They were something else. Something that Nebula, used to being looked at with contempt or challenge or indifference, did not quite recognize.

Gamora's eyes said: I see you. I know why you are angry. I have not forgotten what we are to each other.

Nebula's fury wavered.

She retreated.

She disappeared into the black between the stars, and Gamora watched her go. She felt the ache that had lived in her chest since she left the Sanctuary — the ache shaped exactly like a sister. She had not stopped caring about Nebula. She had never stopped.

She understood, now, what she had not been able to understand when they were young. Nebula was not angry at her, not really. Nebula was angry at a childhood that had told her, over and over, that she was not quite good enough. And that anger had nowhere to go except outward, at the person who had always been right there.

Gamora stood in the settling dust of Knowhere and made a quiet promise — not out loud, not to anyone listening. Just to herself.

She would not give up on Nebula.

No matter how long it took. No matter how many times her sister flew away. The door Gamora held open in her heart was not closing. There was always room. There was always a way back.

Out in the dark, somewhere, Nebula's ship blinked away into the stars.

Gamora let out a slow breath.

Then she turned around, and went back to her family.
