Science fiction

Science-fiction, sometimes referred to as sci-fi or speculative fiction is a type of fiction that deals with either futuristic technology, entities from beyond our world, a mix of the two or similar concepts. It is often compared to Fantasy, as the two genres have much in common. In the land of Equestria, science-fiction has quite the following.

Science fiction in My Little Pony
Although characterized as a high-fantasy series for the most part, in truth My Little Pony is as science-fantasy as they come, meaning it blends sci-fi and fantasy in various ways. Usually, the science-fiction elements don't compliment the fantasy elements per say, but exist alongside them. Several sci-fi tropes including time travel, space travel, dimensional travel and so on have appeared in unabashed forms in My Little Pony since the first generation. Likewise, the show has crossed over with sci-fi works, such as Transformers and ROM Spaceknight.
