Katie Ka-Boom (Animaniacs)

Katie Ka-Boom is a character from Animaniacs. She is a 16-year-old teenage girl who greatly overreacts to trivially upsetting situations and literally turns into a flaming monster before subsequently exploding, usually leaving the family home in ruins. She's voiced by Laura Mooney.

Intentional Bad Qualities

 * 1) She turns into a monster whenever she gets angry or doesn’t get her way.
 * 2) She overreacts way too much and is very immature.
 * 3) She is also destructive and keeps destroying her family's house whenever she's a monster.
 * 4) She isn’t aware of her destructive behavior whenever she turns back to normal.
 * 5) She tries to abuse her family whenever she's a monster.
 * 6) She also doesn’t seem to take criticism and justifies this by saying that she's a teenager whenever she's overreacting.
 * 7) Her monster forms, while creative, are disturbing to look at.
 * 8) She is also a mean popular girl stereotype.
 * 9) She never gets punished for her actions or how she treats her family badly.
 * 10) She had also made Trina Riffin from Grojband look like a saint to her in comparison due to her extreme anger issues, much like Tom's abusive owner from the Gene Deitch era of Tom and Jerry.
 * 11) Overall, she is indeed a badly-written parody of She-Hulk, but with none of her likability and charm.

Good Qualities

 * 1) Laura Mooney does a decent job voicing her.
 * 2) She is much better whenever she's not a monster or angry.
 * 3) Her design is pretty lovely whenever she isn't a monster.
 * 4) It's revealed in episode 5 of the reboot that Chicken Boo killed her and stuffed her.
 * 5) She presumably wasn’t meant to be a liked character in the first place for her dangerous temper.

Trivia

 * Katie Ka-Boom is created loosely based on Nicholas Hollander's own teenage stepdaughter who would often explode at every little thing that went wrong.
 * She is a parody of both Bruce Banner/The Incredible Hulk and Jennifer Walters/She-Hulk.
