Speed Force

The Speed Force is the source of Barry Allen and Eobard Thawne's speed.

History
After travelling back to the year 2000, Eobard Thawne lost his connection to the Speed Force due to copious amounts of time travel. Fifteen years later, Thawne was able to use a Tachyon Prototype to access the Speed Force, absorbing some of it and allowing him to run at high speeds, and vibrate his body and voice.

Sometime later, needing to remove a bomb from his wrist without it exploding, Eobard motivated Barry to become one with his speed, thus becoming one with the Speed Force, allowing him to phase through a tanker, removing the band.
