Steven Universe

Steven Universe is an animated American TV show about a young teenage half-human half-Gem hybrid named Steven Universe and his adventures with his three overseers Garnet, Amethyst, and Pearl, the three remaining members of the army known as the Crystal Gems. On his journeys, Steven learns about his Gem heritage and abilities through not only his guardians, but through accidental discoveries and even his enemies as well. He and the Crystal Gems live in Beach City, a small beach coast residency inhabited by humans who don't find magical rock people from outer space strange all that much.

Gems
Gems in Seven Universe are an almost all-female race of magical gemstones that came from outer space. Their bodies are illusions that allow the actual gem (the gemstone on the body) to move and fight. Gems don't need food, water, or sleep like how humans do, although some do eat, drink, and rest on occasion. When a Gem's body is badly damaged, it will release its physical form to retreat to its gem so then it can heal and return in better shape than before. If a Gem returns from healing too soon, however, it may have its body deformed or abilities become hardly usable, as seen in "Reformed". If a Gem is struck hard enough by an incoming attack, it will be shattered, the Gem equivalent of being killed. Shattered Gems cannot heal and are forever lost unless the pieces of their gemstone are placed in the solutions of all the Diamonds, effectively resurrecting the once-shattered Gem to full health. As Gems are a space-faring race, their bodies of light will adapt to the gravity of the planet or moon that Gem is currently on. Like how the episode "Adventures in Light Distortion" has shown, if a Gem is moving faster than the speed of light, the body will lag behind the gemstone until the Gem returns to slower-than-light speed.

Steven Universe Season 1
The first episode of Steven Universe, "Gem Glow", focuses on Steven's struggles with figuring out what the trick to summoning his shield, inherited from his mother Rose Quartz, through usage of his Gem powers is. He encounters a corrupted Gem in the form of Centipeedle, a giant centipede-like monster, who is threatening Beach City on its beach. After their battle with the Centipeedle, Steven and the rest of the Crystal Gems — Garnet, Amethyst, and Pearl — go on adventures and solve problems such as Steven feeling like he's not valuable to Garnet, Amethyst, and Pearl. In "Bubble Buddies", Steven gets a chance to introduce himself to a girl he likes, Connie Maheswaran, but he leaves a bad first impression on her by endangering himself and her with his powers he still hardly has any control over. After the bubble Steven inadvertently formed suddenly pops, he and Connie are freed and become friends. Connie will become a very important character later. "Steven's Lion", the series's tenth episode, introduced Lion, a pink magical lion Steven meets in a desert who he befriends shortly after meeting him. Lion joins Steven in future battles and acts as a Quick Travel vehicle for him with his portal-creating roars. In "An Indirect Kiss", Steven learns that he can heal the gemstones of Gems by applying his saliva to them, an ability that, like his shield, he got from Rose Quartzundefined. The next two episodes, "Mirror Gem" and "Ocean Gem" in that order, are about Steven and the rest of the Crystal Gems meeting a new Gem who was trapped inside a mirror for 6,000 years by the name of Lapis Lazuli. The main problem in "Ocean Gem" is Lapis Lazuli has moved the ocean to an area where she plans to use the ocean's water to form a pillar that would reach all the way to Homeworld since she wants to return to her home. After Steven heals Lapis's cracked Gem, she flies off into space with wings of water. Steven, the Gems, Greg, Lion, and Connie return the ocean to its place and are called heroes by the people of Beach City.

The second part of season one starts with Steven learning more about himself, the Gem race as a whole, and the ones he loves. In "Watermelon Steven", he makes an Accidental Discovery about another one of his abilities: Floral Sentience. In the episode, he unintentionally gives life to watermelons that were formed in his image. These living watermelons act as Steven's guards who attack anything that threatens his well-being. In the very next episode, "Lion 3: Straight to Video", Lion shows Steven a dimension that can be accessed solely by Stevenundefined using Lion's mane as a doorway. In "Warp Tour", Peridot, a Homeworld technician Gem, makes her debut. Although she does very little in the time she appears, she will become very relevant to the story later. In "Alone Together", Steven learns that he can fuse with Connie and does so to form Stevonnie. "Future Vision" introduces the titular Clairvoyance-like ability Garnet owns that allows her to see the different possibilities of the future. "Marble Madness" sees the return of Peridot and her helper robots. This is the first time that Steven gets to talk directly to Peridot. The episode "Rose's Scabbard" explores the history of the Rebellion, a war fought between the Crystal Gems and the Homeworld Gems who wished to seize control over Earth. A new enemy of the Crystal Gems, Jasper, makes her debut in "The Return" with the title referring to the return of Lapis Lazuli and Peridot. After Jasper headbutts Steven and captures him on the Gem Warship in "Jail Break", Steven must venture through the ship with Ruby, one of the Gems who form the Fusion Gem Garnet, and find Sapphire, the other Gem required to make Garnet. In the end, Steven breaks out with the rest of the Gems as they all cause the ship to crash land on Beach City next to the temple. Lapis Lazuli captures Jasper in a fusion known as Malachite, saying she's holding who previously had her as a prisoner as such, at the bottom of the ocean. This episode is the season finale of season 1.
