Even my own parents never thought I could do this. Guess I'm still proving them wrong. People always underestimate me, whether it's an idiot like Killcannon, or an entire army of alien invaders. But they don't realize I'm not gonna stop. Not gonna give up. No matter who comes for me... I'm going to fight for this planet... my way.”

—Atom Eve in Invincible VS

Samantha Eve Wilkins, also known as the superhero Atom Eve or Eve for short, is the tritagonist of Invincible and the main protagonist of Invincible: Atom Eve. She is a genetically enhanced human, the biological daughter of the late Polly and an unnamed man, and the adoptive daughter of Adam and Betsy Wilkins. She is also the girlfriend of Mark Grayson and the mother of his unborn child.

Born as the U.S. government's ultimate weapon, she was rescued by her creator, Dr. Elias Brandyworth, at her dying mother's wish and entrusted to the Wilkins family to be raised as their adoptive daughter. In her pre-teen years, Eve emerged as a hero with the ability to manipulate matter at a subatomic level. She was a past member of the Teen Team before they disbanded for auditions for the new Guardians of the Globe. While she excelled in the trials, Eve decided to become an independent hero. After beginning a relationship with Invincible, they founded a superhero security firm called Invincible Inc. for financial support. Prior to the Viltrumite War, Eve discovered she was pregnant with Mark's child, which was the cause of her powers malfunctioning, but she didn't inform Mark before he left for the war. During his absence, she had an abortion, which led to the restoration of her powers, which she informed Mark of after his return, after 10 months of absence. In early 2025, after Mark's parents, Nolan and Debbie Grayson, left Earth for Talescria to be with Oliver, Eve took up residence with him at his family home.
