"Well... the accelerator went active. We all felt like heroes, and then... it all went wrong. The dimensional barrier ruptured, unleashing unknown energies into our world. Antimatter, dark energy, x-elements..."
Harrison Wells[src]

Dark matter is the collective term given to subatomic particles which are capable of altering a human's biological structure to turn them into meta-humans and allow them to develop superpowers. The vast majority of dark matter in the series was released from the S.T.A.R. Labs particle accelerator explosion in 2013, though there have been other sources of dark matter too.


Ancient times

A mystical black diamond that has existed since ancient times is made of dark matter.[1]

Modern instances

S.T.A.R. Labs particle accelerator exploding.

On December 11, 2013,[2] the S.T.A.R. Labs particle accelerator activated for the first time, but due to sabotage from Eobard Thawne ends up causing an explosion which releases dark matter all over Central City. Many who got exposed to the dark matter wave ended up developing powers and became meta-humans, including Barry Allen who would become The Flash. Many of those who became meta-humans would go on to use their powers to commit crimes.[3]

On Earth-2, there was a similar explosion with the S.T.A.R. Labs particle accelerator. Dr. Harrison Wells attempted to minimize the damage by directing the dark matter wave underground to limit people's exposure to it. However, there were still many people exposed and turned into meta-humans as a result.[4]

Central City Bus 405 getting hit with dark matter

In 2017, Clifford DeVoe manipulated Team Flash to release The Flash from the Speed Force by sending the Samuroid to attack Central City. At the breach where Barry returned from the Speed Force, DeVoe had orchestrated for Central City Bus 405 to be right underneath. This exposed everyone on board to the dark matter and each of them in turn became meta-humans with powers that DeVoe had carefully anticipated.[5]

Harry Wells created his own version of a Thinking Cap in order to combat the Thinker. However wanting to further charge up the Thinking Cap, Harry used dark matter to further enhance it and empower his intelligence. The addition of dark matter ended up having a detrimental effect on his neurons and caused him to lose his intelligence.

During the Enlightenment, DeVoe launched five satellites (one of which Barry Allen destroyed, prompting DeVoe to use the S.T.A.R. Labs satellite to replace the one Barry had eliminated) which Clifford then loaded with dark matter in an attempt to reset the minds of everyone on Earth. However, after the Enlightenment was thwarted by Team Flash, DeVoe instead sent the S.T.A.R. Labs satellite plummeting towards Central City. Barry (with the help of Nora West-Allen) manage to destroy the satellite, but as a result dark matter infused debris rained down upon Central City and created meta-tech as well as more meta-humans.[6]

The meta-human cure surpresses dark matter.

In 2019, Ramsey Rosso attempted to create a cure for HLH using dark matter as a binding agent.[7] This led to him becoming the meta-human known as Bloodwork who was able to spread his dark matter-tainted blood to infect others.

  • Dark matter gives powers based on personal attributes or material a person is in contact with when the energy hits them.
  • Jesse Wells only became a speedster after getting hit by dark matter because Barry gave her a zap of Speed Force to wake her from her coma.

Behind the scenes

  • In the real world, dark matter is a form of matter thought to account for approximately 85% of the matter in the universe and about a quarter of its total mass–energy density or about 2.241×10⁻²⁷ kg/m³. It is named as such due to the fact it is invisible and in all respects undetectable aside from the gravitational force it leaves upon normal matter.
