"I wouldn't get too attached to little Bunsen if I were you!"
— Amanda

Amanda Killman is the main antagonist of Bunsen Is a Beast.


  • In Astro-Nots she says "I have a bladder the size of a cow" to herself, indicating she can avoid urination for long periods.
  • She is often seriously injured so must be durable and a rapid healer to survive
  • She has strength fueled by rage, as indicated by crossover

Amanda is a thin girl with a pale skin tone. She has blonde hair tied into two little pigtails held by blue bands. She wears a dark blue bow and has freckles. She has dental braces and a slight lisp. She wears a school-girl like uniform with a white T-shirt, red vest, striped blue skirt, light blue socks, and black Mary Jane shoes.




Amanda regularly compliments herself or fishes for compliments from others as a narcissist may. For example

  • when Bunsen and Mikey visit her home she is referring to herself as a blossoming ingénue.
  • in Cookie Monster when Mikey is trying to inform her she became a beast "You just turned into a B..B..." she interjects. "Spit it out Munroe. A blossoming ingénue? A bodacious babe? A bucket of hubba hubba? Tell me something I don't know."

Boys in general

Mikey is not the only boy she has made salacious comments about.

In one episode when being hauled off by cops says "men in uniform, I like it."

In another when in a tank with General Lance Justice and his men, she comments "tank tops, I like it."

At the end of Hall of Justice she comments "boys locker room, I like it."

To 3 headed alien in Astro-Nots: "You know your little face is kind of attractive. Care for some tube sushi, handsome?"

In Cookie Monster she plays the damsel in distress for Jerk Von Handsome


She and Bunsen are likely enemies, although Bunsen doesn't view anyone as enemies at least of what he thinks. Her main agenda is to rid Bunsen out of town at any attempt she makes, even if she ends up failing and getting caught.


She and Mikey are enemies. However it is implied that she may have a crush on him in various episodes.

In "Bunsen Screams for Ice Cream", she accidentally mentions that he looks good in gym shorts.

In "Beast Busters", she whispers "Mama likes" when noticing that Mikey has a glistening tan.

"Fright at the Museum" when Mikey is disguised as a lamp in an exhibit, Amanda says the lamp looks attractive.

In "Beastern Standard Time" in an alternate Muckledunk dominated by donuts, she romantically reacts to a portrait of Mikey and states she will be marrying him.

In Unhappy Campers she says "my spirit animal is the beast of Muckledunk Bog, because we both find Munroe scrumptious" and begins petting his face as she says the last part. She then says "the last part slipped out but the first part was meant to terrify you."

In Cookie Monster: "What's that delectable-looking confection? And for once I'm not talking about Munroe."

In Mikey-plication she bribes Mikey with cupcakes to form the "Amanda Stares at Mikey and Makes Tiger Growling Sounds Club".


Beverly is a minion to Amanda. Although they are friends, Amanda usually orders her about.
