Reeling from the loss of Nora, Barry throws himself into work, defeating a record number of metas over the summer, while the rest of Team Flash deals with changes of their own – Cisco, having taken the meta-human cure, is no longer Vibe, Joe is now Captain of CCPD, D.A. Cecile Horton is now considering leaving the district attorney’s office, and Ralph Dibny is now searching for a missing heiress named Sue Dearbon.  But all of that is put on hold when Dr. Ramsey Rosso, intent on curing death, is overtaken by his own desperation and ambition giving birth to a new villain… Bloodwork.[2]

On March 12, 2019, it was reported that Todd Helbing, who had been serving as showrunner for the past two seasons, would be stepping down his position with the intention of focusing on the development under his overall deal with Warner Brothers Television. Eric Wallace, who has been a co-executive and executive producer since the fourth season will take over the position as sole showrunner beginning this season.[3]


Filming for the sixth season began on July 2, 2019, and was scheduled to conclude for April 6, 2020.[4]

On March 13, 2020, The CW suspended production for The 100 and The Flash due to the coronavirus.[5]


Critical response



  • The season was originally set to consist of 22 episodes, with the season finale airing May 19; however, it was later shortened to 19 episodes, as the remaining three planned episodes were unable to be produced due to the COVID-19 pandemic.[6][7][5]
  • This was the only season to not receive a single 0.2 rating or sub-million viewership for any episode in the 18-49 demographic during The CW's 2019-20 broadcasting season.
