Fans of the comics know that Atom Eve eventually learns that she is immortal in the Invincible comic books. In a later issue of Invincible, Atom Eve's powers revert her back to her younger self.

The prime Immortal has not yet died in Invincible Season 3 and is currently alive. However, an alternate version of the character who plays a prominent role in Episode 4, “You Were My Hero,” dies.
