For its Earth One equivalent, see S.T.A.R. Labs particle accelerator.

The S.T.A.R. Labs particle accelerator is a device that was created by S.T.A.R. Labs on Earth Two.


The particle accelerator was designed by S.T.A.R. Labs under the orders of Dr. Harrison Wells to power all of Central City with clean energy. However, when they turned it on, something went horribly wrong and the particle accelerator exploded underneath S.T.A.R. Labs, sending a huge shock-wave of dark matter in to the clouds and through the entire city, subsequently creating an unknown number of meta-humans.[1]

Known victims of the particle accelerator explosion




  • Unlike the Earth One version, the accelerator didn't explode publicly above ground. This could explain why Earth Two S.T.A.R. Labs is still operational while Earth One S.T.A.R. Labs was crippled.
