One idea could be an OC named Ruby - Quartz. She is half Ruby and half Quartz. Her story could start with her feeling out of place among the full - gem characters. She has the fiery passion of a Ruby but the calm stability of a Quartz. As she tries to find her identity, she meets Steven and the Crystal Gems. They help her understand that being a half - gem doesn't make her any less special. She then uses her unique combination of powers to help save the day during a battle against a new Homeworld threat.
A plot could involve a half - gem OC who is half Emerald and half Peridot. The OC is discovered by a group of rogue gems who want to use her unique powers for their own gain. She has to escape from them and find her way to the Crystal Gems. Along the way, she discovers that she has the ability to create energy shields like an Emerald and hack into technology like a Peridot. Another idea is a half - gem OC half Topaz and half Bismuth. She is born during a time of peace but when a new war breaks out between Homeworld and the Crystal Gems, she has to decide which side to fight for, as she has qualities from both sides.
One common theme is self - discovery. Gem OCs often have to figure out who they are in the context of the Steven Universe world. For example, they might be different from the known gem types and have to learn about their own powers and purpose.
The freedom to tell different stories. In the official show, there are certain storylines and character arcs. But with OC gem fanfiction, you can take things in a completely new direction. You can create a gem from a different colony, with a different purpose, and see how they interact with the familiar characters like Steven, Garnet, Pearl, and Amethyst. It adds a whole new layer of depth to the Steven Universe experience.
Sure. 'The Forgotten Gem' is a great one. It focuses on a new gem OC who has been lost in the universe for centuries and her journey to find her place among the Crystal Gems. The character development is really interesting.
There's 'The Lost Gemstone'. This fanfiction focuses on an OC gem who arrives on Earth and has to adapt to the new environment. It has a lot of heartwarming moments as the OC interacts with the Crystal Gems and learns about love and friendship, which are central themes in Steven Universe.
There's a fanfic called 'Male Gem's Adventure'. In this story, the male gem character starts off as an outcast but then discovers his true potential. It has some great action scenes and also delves into the relationships between the male gem and the other well - known characters from Steven Universe. It gives a fresh perspective on the gem universe.
One idea could be a gem oc who was created with a unique power that the other gems don't understand. For example, the power to communicate with non - sentient objects. This could lead to all sorts of adventures as the oc tries to figure out how to use this power and the other gems try to figure out if it's a threat or a valuable asset.
You need to think about how they interact with the existing characters in the Steven Universe world. Are they in awe of the Crystal Gems? Do they have a rivalry with a particular gem? Their relationships with others can shape their character. For example, if they have a friendship with Steven, they might become more open - minded and accepting of Earth. Also, consider their goals and dreams. A gem oc who dreams of becoming a great artist among the gems would act and think differently from one who just wants to be a great warrior. These aspects combined can create a very believable character for your fanfic.
The Diamonds are extremely popular in gem war fanfiction. Their power and their role in starting and perpetuating the war are fascinating to explore.
