Scooby-Doo and the Alien Invaders

Everything About Fiction You Never Wanted to Know.

The third direct-to-video film based on Scooby-Doo, released in 2000 and featuring aliens from outer space.

Tropes used in Scooby-Doo and the Alien Invaders include:
  • Aliens Are Bastards: The movie seemingly plays this straight, but it ultimately averts it. It turns out that the aliens that are evil are actually humans and that Crystal and Amber are aliens though they're actually good.
  • Distaff Counterpart: Though she's technically from outer space, it's noted that Crystal and Shaggy are a lot alike. The same applies to her dog Amber though she's technically an alien too though she's a more animalistic alien than Scooby. It turns out that like Scooby, she's capable of speech, though it's more coherent.
  • Statuesque Stunner: Shaggy notes that during his love song about Crystal that she is rather tall. Technically, they're about the same height.
