List Rules Vote up the best animated science fiction and fantasy shows that have aired on television.

Animated television shows have a unique ability to create truly fantastical and out of this world fantasy and science fiction worlds. No fancy sets, special effects or costumes - if it can be drawn it can be done! The best animated sci-fi and fantasy shows are more than just “cartoons.” If you’ve been looking for the sci-fi and fantasy stories that'll ignite your imagination while also enjoying the visuals of a cartoon, this list of the best animated fantasy and science fiction series of all time will help you figure out what needs to go into your queue.

Having a talking animal friend or a robot in a cartoon doesn't necessarily make for a great animated science fiction and fantasy show. The fantasy and sci-fi elements need to be a consistent and large part of the story. Some of the best sci-fi cartoons tell the same stories a live-action show would, they just happen to be animated, such as Futurama or the animated Star Wars series. The best fantasy cartoons get to have a lot of fun with the animation and shows such as Gravity Falls and OK K.O.! Let's Be Heroes embrace the flexibility of their medium.

Which animated TV shows tell the best fantasy and sci-fi stories? Vote up the best animated science fiction and fantasy shows, then vote down the cartoons that aren't great examples of the genre, and add any sci-fi or fantasy animated series that are missing.
