Pied Piper

Pied Piper's History

Hartley Rathaway, self-styled as Pied Piper, is the son of Rachel and Osgood Rathaway. A former employee of S.T.A.R. Labs, he was fired by Harrison Wells (Eobard Thawne in disguise) for trying to stop the activation of the Particle accelerator, which he'd discovered was at risk of exploding. After being affected by the particle accelerator and gaining the ability to hear at superhuman levels, Hartley attempted to get revenge on Wells for firing him by trying to kill Barry Allen/The Flash, believing Wells to have replaced him with the Flash. After being defeated by Barry and Wells, Hartley was re-incarcerated, having planned his capture and escape the first time as part of his revenge plan, but not this time. However, he knew the whereabouts of Ronnie Raymond, and Cisco reluctantly worked with Hartley to find Ronnie and succeeded. Nonetheless, Hartley used this opportunity to escape.

In an altered timeline, Hartley's revenge was interrupted by the appearance of a Time Wraith, but worked with Team Flash to defeat it. As a result of the timeline change, Hartley made amends with Team Flash and became an ally of the team, even knowing Barry's secret, and made up with his parents.
