Role in the film
Athena is first seen at the 1964 New York World's Fair, where a young Frank Walker shows off his invention: an experimental Jet Pack, to David Nix. Nix denies Frank admittance to the invention contest he's judging. Athena, seeing the potential in Frank, gives him a Pin, and tells him to follow herself and Nix.
Many years later, she gives a pin to Casey Newton, whom she believes is the key to saving the world.
She is destroyed when Nix tries to shoot Frank, but she sacrifices herself to save him. She then reveals her love to Frank, and self-destructs.
