In the new world left after the Great War, everything has changed. In the shadow of the vast city of Zalem hanging in the sky lies a metropolis where people live amid tons of garbage dumped from above. Crime is rampant here, people are struggling to survive, and biology and technology are fused together. Welcome to Iron City! Alita wakes up in a world that doesn’t know, doesn’t remember how she was born, doesn’t remember who her creators are. She is a cyborg, her mutilated body was found in a landfill by Dr. Dyson Ido. He wants to protect her from her past, but with the help of her new friend Hugo, she tries to uncover the secret of her origins. When the hunt begins for her, Alita finds out that she has unique combat abilities that the powerful rulers of Iron City need. And now Alita must save not only her friends and new family, but also the world that has already become dear to her.
