"It Came From Beyond" is the second half of the sixth episode in the ninth season of Arthur.


Thora Read takes in a stray, an adorable little dog named... Killer? It soon becomes clear that the name fits, as Killer bullies every person and animal in sight. Can Killer let her guard down long enough to make a few friends, or will she have to give up her new home?[4]


On a rainy night, Grandma Thora finds a dog on her porch. It is frightened and growls, but she leaves the door open for it.

It Came From Beyond

The next morning, Thora finds the dog asleep on her couch. The tag on the collar reads “Killer”; Thora thinks that is a "tough name for such a cute little" dog. She gives the dog some food, but it growls again. It only eats after she leaves the room.

Thora hangs up posters with a picture of Killer. When Nemo insults Killer, she growls at him and then at Crusher, the latter of whom retreats.

Arthur and D.W. visit Thora with Pal. Thora warns D.W. to be careful, but she tries to make friends with Killer too fast and is growled at. Pal scolds Killer for her behavior. She acts friendly and offers him food, but then attacks him, scaring Arthur.

At the Reads' house, Pal gives Kate and Amigo an exaggerated account of the attack. When Thora comes with Killer, Amigo tries to be friendly but is bitten. Thora and Mr. Read apologize to Mr. Molina.

Thora takes Killer to the animal shelter, where she learns that Killer has never stayed with anyone for more than a few days. Killer is put in a special room for difficult dogs, but Thora changes her mind and takes her home again. She tells Killer that she has to be nicer.

Pal and Amigo argue over a bone when Killer visits them. She tries to be friendly, but they do not trust her. Kate wants to give Killer a second chance, but Pal says she will never fit in and should leave. Killer sadly goes to say goodbye to Thora.

While hunting a bird, Nemo gets stuck up a tree. He can not get Francine’s or Buster’s attention, but when Killer walks by, she promises to help, although she remembers the insult. Killer is unable to get to Francine, but when a fire truck comes by, Killer stands in its path. The firefighters stop, notice Nemo, and rescue him.

Later, Amigo tells a heroic story about Killer, which he heard from the firefighters’ dogs. Pal agrees that Killer can not be all bad. Pal and Amigo visit Killer at Thora's house, and present her with a bone as an official welcome to the neighborhood. Killer then proceeds to thank and lick them, finishing the episode.






  • Killer was first introduced in the book Arthur's Christmas, published in 1984, pre-dating the first appearances of Pal and Kate in the book series, but this is her first appearance in the television series.
  • In the Croatian dub of Arthur, Killer is male instead of female.

Episode connections[]

  • Crusher is seen with Slink although he is Rattles's dog (unless Slink was for some reason watching him for Rattles).
  • On international airings, the visual title card cuts off when Pal starts walking away while the audio remains intact.
  • When approaching Killer for the first time, Amigo says "buenas días," which is gramatically incorrect. It should be "buenos días."
