First, develop a strong character for your oc. Give her more than just the physical trait of being big - breasted. A good backstory, unique personality traits, and goals are important. For example, she could be a powerful fighter despite some initial insecurities related to her appearance.
I'm not sure specifically which ones are the most popular. However, you can start by looking on fanfiction platforms like Archive of Our Own or FanFiction.net. Search for 'garou' and then filter through the results to find those related to the 'big breasted oc' aspect.
To create a believable OC, start with a clear backstory. For example, if she's from a foreign wizarding school, explain how that influenced her magic style. Also, give her flaws. Maybe she's overly impulsive when it comes to protecting Severus. And don't make her overpowered. If she has a special ability, it should come with limitations.
Don't forget to give it flaws. A robot that is too perfect can be boring. Maybe it has a glitch that causes it to stutter when it gets excited or a fear of water that is a problem since it's often around coolant systems. By creating a well - rounded Robot OC, your fanfiction will be more engaging.
First, you need to have a clear idea of your zanpakuto's abilities. It could be something unique like the ability to control gravity or create illusions. Then, think about the character who wields it. Their personality should complement the zanpakuto's powers. For example, if the zanpakuto is very powerful but hard to control, the wielder could be a headstrong person who is constantly trying to master it.
First, think about the appearance. It could be a combination of different animal features or something completely out of the ordinary, like a floating mass of tentacles with glowing eyes. Then, consider its abilities. Maybe it can fly or has super strength. Next, give it a personality. It could be shy, aggressive, or mischievous. Also, think about its backstory. Why does it exist? Was it created by accident or on purpose?
One important aspect of creating an Ahsoka OC for fanfiction is their motivation. What drives them? It could be revenge for a wrong done to their people, or a thirst for knowledge about the Force. Another factor is their flaws. Maybe they're overly impulsive or too trusting. These flaws make them more relatable. And don't forget about their connection to Ahsoka. It could be a mentorship, a friendship, or even a reluctant alliance at first. This connection can be the heart of many great fanfiction stories.
First, think about the appearance. It could be a unique color scheme, like a pastel purple - haired fairy with wings that have a glittery pattern. Then, decide on a talent. It could be something like singing in a way that can heal other fairies' ailments. Also, consider the OC's backstory. Maybe they were found as a lost fairy and brought to Pixie Hollow, which gives them a sense of being an outsider at first.
First, study the existing Xenomorph lore. Know their biology, like how they reproduce and their physical capabilities. Then, think of a unique trait for your OC.

First, give your quirkless oc a strong personality. Maybe they are extremely brave or have a great sense of humor. Second, define their goals clearly. For instance, they could aim to be the best athlete in a world where most athletes use quirks to enhance their performance. Third, think about their backstory. Were they bullied for being quirkless? Or did they grow up in a loving family that supported them despite their lack of a quirk?
First, study Balthier's character traits. He is charming, cunning, and a skilled pilot. So, your OC could have complementary traits like being an excellent navigator or having a great sense of humor.
