Create a Gem Adventure of Your Own

Steven Universe turns big cosmic stories into questions about love, identity, and how people heal. This adventure game lets you play as Steven, Garnet, Amethyst, Pearl, Connie, or another Gem and choose what kind of mission or emotional journey comes next.

Your story can begin with a corrupted Gem sighting, a Beach City day that gets weird, a fusion lesson, a Homeworld problem, or a quiet conversation that matters more than a fight. The sim can be funny, musical, tender, dramatic, or full of starry danger, depending on the scene you want to explore.

Pick your character, describe the adventure, and let the story respond with heart. Whether you're looking for healing, chaos, found family, or a new Gem mystery, this is your chance to build a Steven Universe episode around your choices.

  • Steven

    Take Steven into a new chapter where empathy and Gem powers are both tested. Help a corrupted Gem, mediate a conflict nobody else wants to touch, explore a strange new ability, or rewrite a major event with the experience he gains later. You can make the story hopeful, emotionally complicated, relationship-driven, or create an alternate future where Steven chooses a different way to grow beyond the legacy left to him.

  • Garnet

    Play as Garnet and see the world through choices shaped by love, leadership, and future vision. Guide the Crystal Gems through a threat with multiple possible outcomes, explore Ruby and Sapphire's relationship, make a decision no vision can settle, or revisit a major event from a new angle. Her story can be cosmic action, romance, leadership drama, or an alternate timeline where one future Garnet once avoided becomes reality.

  • Amethyst

    Play as Amethyst and build a story around freedom, identity, and the parts of her past she still does not have answers for. Explore the Kindergarten, clash with another Gem, take Steven on a reckless adventure, or imagine a future where Amethyst becomes a mentor herself. You can make the story funny and chaotic, deeply personal, friendship-driven, or an alternate timeline where she learns about her origins much earlier.

  • Pearl

    Step into Pearl's story and choose what comes after centuries of defining herself through someone else. Train Connie, investigate an old Gem secret, confront a memory of Rose, pursue a new relationship, or take the lead on a mission that belongs entirely to her. The story can be elegant and emotional, action-focused, romantic, or an alternate timeline where Pearl claims her independence much earlier.

  • Peridot

    Put Peridot on a mission where technical knowledge meets Earth nonsense. Repair alien technology, investigate a strange Gem signal, attempt to understand another human custom, or save the planet with a plan nobody else believes will work. Her story can be science-comedy, friendship, redemption, or an alternate adventure where Peridot's inventions push Earth-Gem cooperation into a completely new era.

  • Lapis Lazuli

    Give Lapis a story about what freedom looks like after spending so long trapped by other people's choices. Explore Earth on her own terms, face a Gem from her past, repair a relationship, or use her enormous power against a threat that drags old fears back to the surface. You can make it quiet and healing, emotionally intense, romantic, or an alternate future where Lapis finds belonging sooner.

  • Bismuth

    Put Bismuth at the center of a Crystal Gem story where building a better future might require confronting old battles. Forge a new weapon, reconnect with another rebel Gem, defend Earth from a threat tied to the war, or revisit the disagreement that once separated her from Rose. Her story can be action-heavy, political, emotional, or an alternate timeline where Bismuth never leaves the Crystal Gems.

  • Connie

    Step into Connie's role and decide what it means to stand beside magical beings without being one yourself. Train with a sword, protect Steven during a crisis, face pressure from normal life, or explore her future as she builds goals beyond Beach City. You can make the story adventurous, romantic, coming-of-age, or an alternate path where Connie takes a much larger role in human and Gem relations.
