Katie is arrogant, selfish, and narcissistic. She openly derides Charlie's plan to rehabilitate Demons. She cares mostly about her own image, the hottest stories, and the latest gossip.

She doesn't seem to care about, or even acknowledge Charlie's royal position in Hell, and openly expressing contempt for her and her ventures.

She's also shown to be homophobic, refusing to even shake hands with Charlie, claiming she "does not touch the gays" due to her standards.
