Amunet Black

"Out? Out of what? Out of options, out of your mind, out of the closet? There's just so many "out's" for the lady in blue. [...] You should know by now that I don't ask for anything. I tell, and I take..."

- Amunet to Killer Frost, when the latter tells her that she's "out".

Amunet Black is a villain in the fourth season of The Flash, appearing as the nemesis to Killer Frost.

Amunet is a powerful crime lord in Central City. Despite her quirky attitude, she is a ruthless and cruel gangster and is feared in the criminal underworld. She appears to be a meta-human with the power of magnetokinesis, allowing her to control and shape all kinds of metal. She has several henchmen, including Norvok and - temporarily - Killer Frost.

She is portrayed by Katee Sackhoff.

Past
Amunet is a power to be reckoned with in the criminal underworld of Central City. She sells stolen technology in the meta-human black market and is also willing to sill humans as well. She is eventually contacted by Caitlin Snow, who fears that her Killer Frost personna is returning and wants to buy power dampening technology from Amunet. Amunet agrees to a deal, however, in return Caitlin must join her and work for her. Caitlin agrees and starts working for Amunet in one of her bars. Over the time, Amunet started to rely on Caitlin and even considered her her favorite henchman.

Problems with Killer Frost
However, Cisco Ramon can convince Caitlin to join Team Flash once more. Caitlin quits working for Amunet, despite Norvok threatening that it will have consequences, and leaves the bar. Norvok swiftly informs Amunet about it and Amunet decides to take action. A few weeks later, Caitlin is a guest at Iris West's bachelorette party. They are interrupted by Norvok, who treatens the group. As a result, Caitlin turns back into Killer Frost and heads into one of Amunet's nightclubs. Amunet is delighted and welcomes Killer Frost. Although Amunet acts jovial and girly, she soon gets colder when Killer Frost states that she wants to leave the organization. She claims that she doesn't ask - she simply takes - and tells Killer Frost to come along as she has an idea that could turn both of them very rich.
