Steven Universe AU (also know as Crystal Gems AU) is an alternate universe usually within Rise of the Brave Tangled Dragons universe and Rise of the Brave Tangled Frozen Dragons universe. In the AU, Hiccup, Merida, Rapunzel and Jack Frost exist within the world of Steven Universe. This can be considered a sub-scenario to Sci-Fi AU.
About this AU[]
In this AU, the Big Four exist within the same universe as the Cartoon Network series Steven Universe.
Here, they could either be humans or Gems - a magical alien race of polymorphic gemstones (their Gem equivalents being "Gemsonas" of the characters). They usually play as members of the Crystal Gems, a group of Gems who rebelled against the Gem home-world and became the guardians of Earth and the humans that live on it.
Featured Characters[]
The Big Four[]
Hiccup Horrendous Haddock III[]
Should he be a Gem, Hiccup is often portrayed as a green or red-colored Gem, "his" weapon being a Gem-based version of his fire-sword Inferno. In other circumstances, "he" would instead wield a Gem-based equivalent of his ornate gronkle-iron shield. Because Gems are capable of many scientific achievements thousands of years ahead of humanity, Hiccup would be adept at the technicals of advanced technology Gems possess much like Pearl, making repairing and producing Earth technology (from cars to weaponry) child's play in comparison. In the case of Toothless, odds are he would be a Gem-based animal very similar to Lion. All in all, Hiccup would be very much like Rose Quartz, and is often placed in the same role as her.
Being (debatably) the most normal of the Big Four, Hiccup is also likely to be a normal Human, acting as a friend and/or love interest to the protagonist much like Connie.
Jack Frost[]
Should he be a Gem, Jack is often portrayed as a blue-colored Gem, "his" weapon being a Gem-based version of "his" shepherd's crook. Much like the original Jack Frost, his gemsona would have powers relegated to ice or the cold much like Sapphire.
In other circumstances, Jack would be a Gem-Human Hybrid much like Steven, the team of Crystal Gems he is a part of being Gemsonas of the Guardians of Childhood.
Merida DunBroch[]
Should she be a Gem, Merida is often portrayed as either a red or green-colored Gem, her weapon either being a Gem-based version of her bow and arrows or a sword (the symbol of the Clan DunBroch and a weapon that Merida is more than capable of using). Should it be the bow, whether or not it would operate like Opal's bow depends on the story. Her name being the Celtic work for pearl, could also have her as a pearl-colored Gem.
Rapunzel Corona[]
Should she be a Gem, Rapunzel is often portrayed as either a pink or yellow-colored Gem, her weapon being a Gem-based version of her frying pan. Much like Rose Quartz, she would most likely possess healing powers and abilities related to plants (given their names) or - more likely - the sun.
Extra Characters[]
Queen Elsa[]
Should Elsa be a Gem, she would be placed as a blue-colored Gem. Her gemsona would have powers relegated to ice or the cold much like Sapphire.
The Guardians[]
Since MiM and Bunnymund aren't originally from Earth and the guardian being magical beings, can easily portray them as a group of Gems; with Gem-based versions of their weapons. North would be a red Gem, Bunny a gray-like or silver colored Gem, Tooth would be placed as green or rainbow colored (ammolite) Gem and Sandy as a yellow Gem. While MiM's moon powers can have him as a moonstone Gem. Jack would most likely be a blue gem or a Gem-Human Hybrid much like Steven, that is part of their group.
Pitch Black[]
Should he be a Gem, Pitch is often portrayed as a black-colored Gem.
Big Hero 6[]
The team are commonly seen as a group of Gems, with their Gem colors matching the main color of their hero armor, while "their" weapons are Gem-based versions of their gear. Hiro is either a purple colored Gem or Gem-Human Hybrid much like Steven, Tadashi is sometimes placed as a purple (or any other) colored Gem or a Gem-Human Hybrid beside his young brother, but there are times when he is featured as a normal human for when he doesn't inherit his Gem parent's powers. GoGo is commonly seen as a yellow Gem, with Honey Lemon as a pink Gem, Wasabi a green Gem and Fred is between as a blue Gem and a human.
Moana Waialiki[]
Should Moana be a Gem, she would be placed as a blue-colored Gem, "her" weapon being a Gem-based and staff version of the oar for her sailboat. Due to her connection and friendship with the ocean, her gemsona would have powers relegated to water much like Lapis Lazuli.
Dennis[]
Dennis being half-human and half-vampire, can easily portray him as the Gem-Human hybrid Steven Universe.
Cassandra[]
After Cassandra merged herself with the Moonstone Opal, in which allows her to control its power of the black rocks, that her new sword is made out of, she can easily be portrayed as a blue Gem.
