Central City is a city located 600 miles from Star City. The city's power grid was being used excessively by Scott Morgan's company, leading to brownouts. Also, a particle accelerator was built by S.T.A.R. Labs, though not long after it being turned on it exploded, causing a shock-wave to blow through the city. This resulted in the creation of an unknown number of meta-humans. Barry Allen/The Flash and the S.T.A.R. Labs' team fight crime against meta-humans in it. Following a black hole that S.T.A.R. Labs failed to shut down before its creation, half of the city has been destroyed.
