Miss Killjoy

Katie is the head Newscaster of Channel 666 news, seen by many as a celebrity Katie flaunts her status as a sign of superiority over others

She an egomaniac who sees herself as the biggest celebrity in hell

Katie is arrogant, selfish, and narcissistic. She cares mostly about her own image, the hottest stories, and the latest gossip.

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

Katie is aggressive and always on edge. She deliberately spills hot coffee on her co-anchors crotch, while insulting and threatening Charlie. At the same time, Katie does not tolerate insults in her direction, and when Charlie snaps and calls her a bitch, Killjoy instantly falls into a rage and rushes at the princess with her fists.

She doesn’t care about her fans and typically sees them as a nuisance. She see’s all others as beneath her and not worth her time or attention.

She’s cruel, unsympathetic, and sadistic. She lacks empathy and compassion. She’s the kind of woman who kicks puppies for fun, and spends her free time burning down orphanages.

She feels nothing for others, yet derives pleasure from reducing others to tears.

She has very little respect for her co anchor Tom Trench. Tom is Katie's colleague. It is unclear if their relationship is purely professional or not.

It is possible that Katie also has a tendency to abuse Tom, seeing that after Tom makes a pun about "nailing" Cherri Bomb, she is seen pouring scalding hot coffee onto his crotch. In reaction to this, Tom can be heard screaming "Not again!", suggesting that something similar has happened to him before, likely also from Katie.

She feels as if Charlie Morningstar isn’t worth her precious time. Katie appears to care nothing for Charlie's status as Princess of Hell, believing that she is "too rich and influential" to do so. She has no reluctance whatsoever in talking Charlie down, and even threatens to bury her.

Katie is extremely doubtful about Charlie's plan to help rehabilitate the denizens of Hell, seeing it as a joke and even going so far as to ridicule her during a live interview.

She then proceeds to get into a fistfight with Charlie after Charlie snatches her pen and calls her a bitch.
