One idea could be a candy that has magical powers. For example, a lollipop that can make the person who eats it fly for a short time. Another could be a world where candies are alive and have their own society, with gummy bears as the hard - working laborers and chocolate bars as the rich elite.
Another interesting concept is to create a 'candy candy fanfic' where Candy has a secret power. For example, she can communicate with animals and they help her in various situations. This would add an element of magic to the story.
One idea could be that Tracey and Candy team up to solve a mystery in Gotham that Batman has overlooked. Maybe they discover a hidden criminal organization that is operating under the guise of a charity. Another plot could involve them getting caught in the crossfire between two major villains and having to use their wits to survive.
Another plot could focus on a friendship turning into a romantic relationship. Maybe two characters who have been friends for a long time start to see each other in a different light. They could go through some misunderstandings and challenges that test their bond before finally getting together.
In a Bleach Candy fanfic, you could have a plot where a mysterious candy starts appearing in Karakura Town. This candy has the ability to make the person who eats it swap bodies with someone else. So, characters like Orihime and Chad end up in each other's bodies and have to figure out how to reverse it. Another idea is that there is a candy that was created by Aizen long ago, and it has been hidden in the Soul Society. When it is finally discovered, it has the power to either destroy or save the entire Soul Society, depending on how it is used. You could also write a fanfic where the mod - souls are given a special candy as a reward for their help, and this candy gives them the ability to take on a more human - like form permanently.
One idea could be exploring the unspoken stories of the ranch hands. Maybe there's a hidden love affair between two of them that has to be kept secret due to the social norms of 1923. Another could be focusing on how a young character dreams of leaving the ranch and going to the big city, but faces many obstacles. And a third idea could be a mystery plot where strange things start happening on the ranch and the characters have to figure out what's going on.
One idea is to make the candies magical. For instance, create a story where the Christmas candies are made by fairies in a hidden forest. And when a child finds one of these candies, it takes them on a magical journey through a winter wonderland filled with talking animals and other Christmas wonders.
One idea could be Android 21's struggle to fit into a world that fears her. She has to prove that she's not a threat and tries to make friends. Another could be her discovery of new powers and how she uses them for good. Maybe she teams up with other characters to fight a common enemy.
One idea could be Vampirina making new friends in the human world who are initially scared but then come to understand her. For example, she could join a school club and have to prove that she's not a threat.
Another plot could involve a crossover within the Darksiders universe. Maybe the Horsemen have to team up with a previously unknown group of characters to face a new, greater threat. This could introduce new dynamics and relationships.
Another plot could be a different version of Vision's 'rebirth' in the show. What if there were more glitches and he had to figure out his identity in a completely different way? This could lead to some really cool interactions with Wanda and the other characters.
