He is portrayed by Eric Nenninger.
At some point, Joseph Carver became the CEO of McCulloch Technologies alongside his wife, Eva McCulloch, as well as a member of Black Hole. During Thawne's Particle Accelerator Explosion, his wife Eva McCulloch was trapped in the Mirrorverse, but due to his failure to rescue her and the mental damage the Mirrorverse did, he preferred to assume his wife as he knew her was gone.
Confronted by Iris West-Allen
After learning of Black Hole and McCulloch Technologies' affiliation with them, Iris West-Allen went off to interview Joseph Carver in order to find a lead. However, Carver rebuffed her and denied any relation to them. Afterwards, he decided to sue The Central City Citizen for defamation. Despite this, Iris obtained information from an informant that could place his company into jeopardy and Joseph was blackmailed into dropping the lawsuit.
Since Joe West was leading an investigation about him, Joseph attempted to have him killed and assigned Peter Merkel to that task. While he failed, Joe decided he had to leave for witness protection.
Confronted by Eva and Death
Esperanza Garcia/Ultraviolet, Kimiyo Hoshi/Dr. Light and Millie Rawlins/Sunshine joined Eva's side for revenge on Carver. Eva kills Carver with mirror shards, despite Flash's attempt to stop her.
- Bilingualism: Joseph is capable of fluently speaking English and Japanese.
- Great business acumen: Joseph is presumably apt at making profitable business decisions due to the success and longevity of McCulloch Technologies in his wife's absence.
