Eliza Harmon used Lex Luthor's Everyman Project to gain powers of super speed.

Harmon was a huge fan of speedsters, and her biggest dream was to become the new Kid Flash with the Teen Titans.

After receiving the Everyman treatment, Harmon moved away from Manchester, Alabama to become one of the original members of Luthor's new Infinity, Inc.

Harmon was unstable, and made an enemy of Luthor after she snapped at him. Her superpowers made it difficult for her to slow down, forcing her to take drugs for reprieve. This causes a major argument between Harmon and Luthor, as well as her other team members.

In Week 21, Harmon is allowed back on the team after Natasha Irons (aka Starlight) pleads her case to Luthor and promises that she's off "the sharp."

On a routine takedown of supervillain Blockbuster, Trajectory's powers suddenly short out and she plummets to her death. It seems that making an enemy of Mr. Luthor is never a good idea, as we are shown that Luthor himself pressed the button that caused Trajectory to lose her super speed and her life.
