Descendants 4: Rise of the Underworld is the 4th movie in the Descendants movie series.


After the 3rd movie, Scarlet got help from Hemon in order to get revenge on the VKs. But, Hemon has other plans...


  • This is the second time Scarlet wants revenge on the VKs.
    • It revealed that the backstory behind her mother will be revealed in the 5th movie.
  • This is the 4th time Queen Sia (Scarlet's mom, and Scout's grandmother) was mentioned in the movie.
  • This is the only movie in which the VKs totally lost a battle.
  • At the end of the movie, Scarlet said, "This isn't over yet" which is a different version of "You didn't think this was end of the story. Did you?"
