Trajectory

Trajectory is a fictional superheroine in DC Comics.

Originally from Manchester, Alabama, Eliza Harmon was chosen by Lex Luthor to participate in the Everyman Project after she came to him begging to be granted superspeed. Her wish was granted, and she became a member of Luthor's new super-hero team. However, she was not able to slow down to normal speed without taking the drug known as the Sharp. She blamed this predicament on Luthor and left the team.

Weeks later, she had stopped using the Sharp, and her friend and former teammate, Natasha Irons, convinced Luthor to let her back on the team. She hoped to one day move on to become a member of the Teen Titans and become the new Kid Flash. However, her dream was cut short, as Luthor stripped her of her powers at a crucial moment in a battle with Blockbuster, and she was killed.

The character appears in The Flash, portrayed by Allison Paige. Here, Eliza Harmon is a scientist at Mercury Labs who once helped Caitlin Snow with the Velocity 9 formula, which was used to try and restore Jay Garrick's lost speed. Even though Caitlin never gave her the entire formula, Eliza managed to reverse engineer the drug. She becomes hooked on Velocity 9, blaming her addiction on work pressure and manifesting another "evil" personality to justify her actions to herself. Trajectory becomes a criminal speedster and causes havoc in Central City. After the Flash defeats her, she takes another dosage while already on one and disintegrates while running at high speeds, her body pushed beyond its limits.
