Katie Ka-Boom (Animaniacs)

Katie Ka-Boom is a character from Animaniacs and the titular main antagonist of the show's side-segments, Katie Ka-Boom. 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 Qualities That Make Her Go Ka-Boom!!!!!

 * 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 never even learns her lesson about being destructive towards her family and always gets away with it scott-free.
 * 11) She had also made Trina Riffin from Grojband look like an incomparable 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.
 * 12) 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.
