Sakura is often very popular in Cardcaptors fanfic. She's the main character in the original series, so it's natural that she features prominently. Syaoran is also a favorite. His relationship with Sakura and his own journey of growth are often explored in fanfic. Keroberos is another popular character. His cute yet powerful and sometimes mischievous nature makes him a great addition to fanfics.
One interesting idea could be a fanfic where Sakura discovers a new set of Clow Cards with powers she has never seen before. This could lead to new adventures and challenges as she tries to capture them. Another idea is a fanfic that focuses on the relationship between Sakura and Syaoran after the events of the original series, like how they deal with their feelings in a more grown - up way. And also, a fanfic where the Clow Cards start to malfunction and cause chaos in Tomoeda, forcing Sakura to find a different way to restore order.
Sakura is an obvious choice. She is the main character, and there are so many aspects of her character that can be explored further in fanfiction. You can write about her growth as a Cardcaptor, her feelings towards her friends and family, and her evolving magical abilities. Another great character is Syaoran. His backstory as a descendant of Clow Reed and his journey from being a rival to Sakura to a close friend and potential love interest offers a lot of material. Tomoyo is also a great character to focus on. Her unwavering support for Sakura and her love for designing costumes can add a unique touch to a fanfiction.
You could write a Cardcaptors Sakura fanfiction where Sakura discovers a hidden power within herself that is not related to the Clow Cards. Maybe it's a power that has been dormant in her family for generations. She has to learn how to control this new power while still maintaining her duties as a Cardcaptor. Or perhaps a story where the Clow Cards are stolen by an unknown enemy and Sakura has to track them down without the use of her Key and Staff, relying only on her wits and the help of her friends. Also, a fanfiction about Sakura's life in the future as a full - fledged magician could be interesting.
If Chelsea discovers a long - lost power that Sakura has, it could lead to a power - up for Sakura. This would then shift the balance in any battles or challenges she faces in the fanfic. For example, if the discovery is made during a fight with a powerful card - created monster, Sakura could use this new power to defeat it and save the day. This would also change the relationships between the characters as they see Sakura in a new light.
The Walking Dead comic is extremely gory. It features detailed depictions of zombie attacks and human-on-human violence that can be quite disturbing. But it's all part of the gritty and intense world it creates.
Common themes in hunchback cartoons could include the struggle for social acceptance, the journey of self-discovery, and the importance of friendship. They might also touch on issues like overcoming physical limitations and finding one's place in the world.
