List RulesVote up the most plausible dark Steven Universe fan theories.

Filled with hyper-magical space rocks and an expansive terrain of intergalactic turf wars, there's no wondering how or why Steven Universe has accumulated a mass of devoted followers and fans. What does a drove of dedicated sci-fi cartoon nerds come with? A mass of crystal gem theories, of course! As the show slowly uncovers, shatters, and reworks its entire story, Steven Universe theories soar through the stars in search of the truth behind the Rose Quartz, the diamonds, and the crystal gems.

During the ongoing war between Homeworld and Earth, massive weapons are revealed, terrifying technology makes its ominous presence, and magical, mind-bending powers are exposed. Without a doubt, fan theories about Steven Universe prove to be just as elaborate as the storyline itself, taking both important and blatantly obvious parts of the world's lore and stringing them together with more subtle hints and bits of foreshadowing to make sense of what's really going on.

    White diamond is void of all color because she has been drained of all of the valuable parts of herself. The White Diamond we have seen is only a shell, as she has divided her personality into the other colors - Yellow, Blue, and Pink. Since the gems are able to fuse, this would simply work as the opposite of fusion for her. ChannelFrederator goes in depth about emotion ranges and personality traits that contribute to the diamonds, their powers, and their places on the color spectrum.

    BidGem debates the linguistics of the gems, and why some can understand English, and some can't. He speculates that all gems speak English, and any gem that says that they can't is just exposing a prejudice towards humans. While they do have their own gem language, they only use that language for their writings.

    When Rose Quartz exchanged her life for Steven's, it was no mistake - in fact, it was a well-planned strategy. Rainbow Quartz unravels the reason why a powerful and protective gem would exchange her life for a human's, and it's ice-cold. Since Steven can handle anti-gem technology, this makes him a well-crafted weapon made to defend planet Earth from the forces of Homeworld.

    When A Gem Is Shattered, It Creates A Catastrophic Explosion

    Over on Tumblr, the-grand-author-ne contemplates what it would be like to see a gem get shattered on screen. Since gems become incredibly unstable when they crack and make giant indents from their explosive energy when they poof, this theorist thinks that a gem shattering would be a truly catastrophic event. They think that this could explain the odd terrain of the world of Steven Universe, mainly that giant hole in the middle of Russia.
