BLOC (Earth-Prime)

"It's a Biometric Lightning Oscillation Chamber, technically. We call it the BLOC. It's built with quantum computing to remotely harness lightning from the Earth's upper atmosphere and turn it into artificial speed."

- Meena Dhawan

The Biometric Lightning Oscillation Chamber (BLOC) is an advanced device that was thought to be harnessing lightning from the Earth's upper atmosphere and transform it into artificial speed, though in fact connects to the Negative Speed Force.

Birth of the Reverse-Flash
In the twenty-second century, Eobard Thawne created the first Biometric Lightning Oscillation Chamber in an attempt to give him superhuman speed, similar to his idol, later enemy, The Flash. However, unbeknownst to Thawne, the Negative Speed Force saw him as a potential avatar and connected itself to Thawne's body, giving him the speed he wanted and transforming his hatred as fuel for his powers. Thawne, using his now exceptional speed, became the Reverse-Flash and fought against The Flash.

Fast Track Labs
Soon after a Time Remnant of Thawne was resurrected, he subconsciously built the BLOC with his partner Meena Dhawan. As Dhawan suddenly collapsed due to her heart condition, Thawne placed her in the BLOC, giving her a temporary connection to the Negative Speed Force and allowing her to regain consciousness.

Functions

 * Connection to the Negative Speed Force: The BLOC can connect whoever in physical contact to the Negative Speed Force, giving them temporary superhuman speed.
