Chapter 1 - Guardians of the Galaxy

Seraphina is the third daughter of Thanos, taken in after he slaughtered the rest of her species, commonly known across the galaxy as Angels. She was experimented on, just like her older sisters, and trained to be a great warrior.

When Gamora tells Seraphina of her plan to escape Thanos, she instantly agrees to help her sister, desperate to escape from their horrible father.
