5) Jyn Erso
The main protagonist of the spin-off Star Wars movie starts off not really caring about the Rebellion in the first place. All she sees them as is an asset in her efforts to find her father, even while they secretly want Cassian to end him as soon as he’s found. It’s only after her dad has died in her arms that she realizes the full scope of the situation, and goes to Scarif with the other Rebels to grab the Death Star plans and upload them to the Rebellion.
How she dies: Jyn’s able to upload the plans to the Death Star, and even survives a short encounter with Lieutenant Commander Orson Krennec, but she and Cassian don’t die in the heat of battle. Grand Moff Tarkin uses the Death Star on the beach of Scarif, and she and Cassian embrace as the ensuing shockwave consumes them and everyone else on the beach. Certainly tragic, and props to her for transmitting the plans and telling off Krennec with a gun to her face, but also sorta just… there. This is her story, and odds are that she would’ve died there on that tower if Cass wasn’t there to save her. Great view of the sunset, though.
“You know who I am. I’m Jyn Erso, daughter of Galen and Lyra Erso.”
