Black Hole is the secondary antagonistic faction in the second Graphic Novel arc of Season 6 of the TV series The Flash. It is a mysterious crime syndicate of individuals currently employing Light-based meta-human assassins to cover up their antics.
Black Hole was created at some point before 2013.
Black Hole then took in Esperanza Garcia, grooming her into an assassin whilst using her meta-human abilities to their advantage. They would then do the same thing to Kimiyo Hoshi. After Iris West-Allen met with an informant from McCulloch Technologies, The Central City Citizen looked into McCulloch Technologies' involvement into Black Hole, Black Hole then ordered Kimiyo to murder Iris West-Allen on their behalf. However, she continued to pursue the lead, meeting Joseph Carver to unearth his affiliation with the group. Despite being unsuccessful, Kimiyo attacked Iris after meeting with her informant, leading to him being killed. She then infiltrated Carver's office, using a key from the group to break into a room. She was then abducted through a mirror after trying to gain information from Carver's computer.
