    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.

    Why She Intentionally Goes Ka-Boom! (And not in a good way)

    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.
      • Her monster form in Belly Button Blues is just rather downright ugly and out-of-place as it is nothing more than just an overweight female goblin throwing a tantrum over clothes.
    8. She is also a mean popular girl stereotype.
    9. She never gets punished for her actions or how she treats her family badly, thus making her a karma houdini.
      • She never even learns her lesson about being destructive towards her family and always gets away with it scott-free.
    10. Much like Tom's abusive owner from the Gene Deitch era of Tom and Jerry, Katie is so easy to anger, that she makes Trina Riffin from Grojband and Momma Robotnik from Adventures of Sonic the Hedgehog look like incomparable saints. Heck, even Benson from Regular Show and Nicole Watterson from The Amazing World of Gumball are pacifists compared to her because at least they usually have a good reason to be angry.
    11. She is also the Music Gamble from Music (2021) of Animaniacs, but worse.
    12. Overall, she is indeed a badly-written parody of She-Hulk, but with none of her likability and charm.

    Redeeming 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 an eldlritch abomination.
    4. She presumably wasn't meant to be a liked character in the first place for her dangerous temper.


    • 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.
