This was your daughter? You built this body for her? Her name was Alita. She was really...

[Alita looks at a picture of Ido's daughter] Alita: This was your daughter? You built this body for her? Dr. Dyson Ido: Her name was Alita. She was really looking forward to waking up with legs that could run. Alita: You built her a pair of fast legs. Dr. Dyson Ido: She never got to use them. She was murdered. Alita: What happened? [pause] Dr. Dyson Ido: A patient of mine came to the clinic one night, looking for drugs. I was a tuner for the Motorball games, and I had made a machine body for him of obscene strength. He was my demon coming back to me. [flashback shows the cyborg knocking Ido's daughter off her wheelchair before running away] Dr. Dyson Ido: Alita couldn't get out of the way fast enough. Her mother, Chiren, couldn't deal with Alita's death. Maybe she just couldn't deal with me. So I went hunting. I needed to kill him. Maybe I was just hoping that he would kill me. It brought no peace. There were other demons like him out there and I felt, somehow, I was responsible for all of them. So I registered as a Hunter-Warrior. There's nothing noble about it. Alita: Did you ever find peace? Dr. Dyson Ido: I found you. Alita: I'm not your daughter. [pause] Alita: I don't know what I am. Dr. Dyson Ido: I do. Have a look at your original cyber-core. This is your brain. A normal, healthy teenage girl's brain, if there is such a thing. But this is your heart. Part of your original core, powered by an Anti-Matter Micro-Reactor. Alita: So I've got a strong heart? Dr. Dyson Ido: [chuckles] You have a heart strong enough to power all of Iron City for years. This is lost technology. Nobody's made this stuff since... before The Fall. Alita: [chuckles] Yeah, right. So I'm 300 years old? Dr. Dyson Ido: Sweetheart, you are.
