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 that's hardly a city inhabited by humans who don't find magical rock people strange all that much.

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, 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 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 accidentally formed suddenly pops, he and Connie are freed and become friends. Connie will become a very important character later.
