We thought it was over with the Season 5 finale "Change Your Mind," but maybe we'll get something entirely new. Steven Universe ended on a high note with this episode, but knowing that a movie was coming, fans wondered if it was the end of the story.

Steven Universe: The Movie is set to hit the airwaves soon and despite a trailer, we still know so little. We have a villain and a conflict, and we know that it takes place after a time skip, but we have no idea how this all ties together.

Let's do some theorizing, which is what Steven Universe allows its audience to do better than most others. Here's everything we know about the Steven Universe movie.

What's the story?

If you're all caught up on Steven Universe, you'll know that Steven, with the help of the Crystal Gems, managed to bring together all the diamonds for the first time in eons, helping them with their grief over the loss of Pink Diamond (a.k.a. Rose Quartz, Steven's mother). After a tense and emotional standoff with White Diamond, the three worked together to heal all the corrupted gems on Earth before returning to Homeworld.

That's the main conflict of the series wrapped up, right? Well in Steven Universe: The Movie, which takes place two years after the events of the series, a new mysterious gem arrives on Earth with a giant drill that can sap the life out of any organic being on Earth. Steven and the Crystal Gems must work together to save the planet within 48 hours.

Who is this new gem?

Overall, not much is known about the villain besides the fact that she wants "revenge on Steven and his friends," according to the Cartoon Network website.

Considering that this new gem looks a lot like Pink Diamond both in terms of coloring and her outfit, it's safe to say there's some connection there. Her gem is an upside-down heart, and that implies that there's something off about her, but what? Cartoon Network has been quiet about any details but like all elements of Steven Universe, fan theories are all over the place.

In the simplest explanation, she's just another gem. In a screenshot taken from a behind-the-scenes video, you can see a storyboard in the background. Zoom in a bit and it looks like the new villain's name is Spinel. Spinels come in a variety of colors, but for a long time, the red ones were nearly impossible to distinguish from rubies.

But what is her backstory? Does she have one? One of my favorite theories comes from the YouTube channel The Roundtable and posits what's, at the very least, the most plausible theory. The new gem is either a fake gem created to replace Pink Diamond, or was created by another powerful entity that didn't like all the change that Steven enacted at the end of "Change Your Mind." Either way, the idea is that she's a part of a much larger conspiracy and isn't working on her own.

This makes sense considering the structure of Steven Universe thus far, which has ramped up the threats by introducing larger power structures gradually. She could potentially be a creation of another alien racen (we know those exist) or maybe from whomever created the Diamonds. Since nothing has been announced concerning whether Season 5 would be the last season, it seems safe to say that the movie will set up a larger threat for a possible Season 6.

Another theory I've seen suggests that she was once a corrupted gem and is out for revenge on either the Diamonds or the Crystal Gems for not rescuing her sooner. This would create a smooth transition from "Change Your Mind" and would go along with themes of trauma and mental health that Steven Universe has been so good at conveying.

Who made music for it?

Music is a huge part of Steven Universe's DNA. The show itself features a lot of original music, with some episodes being straight-up musicals.

There have also always been some big names in music attached to Steven Universe. R&B artist Estelle is the voice of Garnet, for example, and people like Nicki Minaj, Patti LuPone, and Aimee Mann have all had cameos throughout the years.

That'll continue with the Steven Universe movie, which revealed a number of musicians who provided music for it in the trailer. The full list includes:

  • Rebecca Sugar
  • Aivi & Surasshu
  • Chance the Rapper
  • Estelle
  • James Fauntleroy
  • Aimee Mann
  • Ted Leo
  • Gallant
  • Macie Stewart
  • Jeff Liu
  • Jeff Ball
  • Mike Krol
  • Grant Henry
  • Julian "Zorzy" Sanchez

The full soundtrack will release the day after the movie premieres, but so far a single has been released. "True Kinda Love" features Estelle (Garnet) and Zach Callison (Steven), with lyrics by Sugar, Chance the Rapper, and Macie Stewart.

Who in the cast is returning?

Steven Universe: The Movie is looking like a full-on reunion of the show's diverse cast of characters.

Here's a cast list, according to Warner Media, that shows off just how many characters are returning in some form, including all the (currently living) diamonds and a couple fusions.
