Cosma

"You have been wasting your time and ours attacking a bunch of kids across the street instead of building robotic henchmen! Our production scale is completely below quota! Why do you even feel the need to attack these kids in the first place?!"

- Cosma to Lord Boxman Cosma, or Ms. Cosma, is a supporting antagonist and bigger bad in ''OK K.O.! Let's be Heroes''. She is an investor of Boxmore Inc. and a business partner of Lord Boxman.

She is voiced by Marina Sirtis, who also portrayed Demona, Queen Bee in Young Justice, Mary Ann Eagin and Detective Inspector Walker.

Don't Attack the Plaza
In "Don't Attack the Plaza", Cosma, along with Vormulax and Teamster, attend a meeting with Lord Boxman. As Boxman tries to run out to destroy Gar's Bodega, Cosma snaps and berates him for constantly abandoning his job to attack "a bunch of kids across the street". Cosma then tells Boxman that his production sales are dropping and that, if he doesn't keep focus and get business back on track, she and the other investors will fire him. When Boxman points out that, as his investors, they can't technically fire him, Cosma states that they will stop investing in his company, meaning that it will go out of business. Cosma then challenges Boxman to not attack the Plaza for an entire day before leaving.

After his investors leave, Boxman states that Cosma should've given him a harder challenge, only to slowly realize that he has an obsession with attacking the Plaza. At the end of the episode, Cosma congratulates Boxman for (technically) not attacking the Plaza all day and decides to continue funding his company.

Appearance
Cosma is a tall, reptilian creature with orange scales and large, prominent yellow eyes and a short snout. She also has medium-length tawny hair and two spikes on either side of her head protruding from beneath her hair. Her outfit consists of a sky-blue bodysuit with a slightly darker center wrapping around her waist. She also has a set of cerulean gloves, boots, and shoulder-pads of the same color.

Trivia

 * Although technically a minor character, Cosma is a bigger bad in the series, due to investing Boxmore Inc. and therefore allowing Boxman to continue making robots to attack the Plaza.
