Another theme is a distorted sense of self - importance. These characters think they are superior and their goals are the most important. Take Zim from 'Invader Zim' again. He believes that his mission to conquer Earth is of utmost importance and doesn't care about the harm he causes in the process. He is so self - centered that he can't see the flaws in his plans. In general, these characters often have a warped view of the world around them and their place in it.
One common theme is the lack of empathy. Psychopaths in these stories often don't understand or care about the feelings of others. For example, in 'The Tell - Tale Heart', the narrator kills the old man without any real consideration for his life or the pain he'll cause. Another theme is manipulation. They are often very good at getting what they want by manipulating those around them, like the character in 'The Cask of Amontillado' who tricks his friend into the catacombs.
Often, there might be themes of mystery and danger. Since a psychopath is involved, the story could revolve around Sakura trying to solve the mystery of the psychopath's actions or escaping from their clutches. There might also be themes of psychological manipulation as the psychopath tries to influence Sakura or those around her.
One common theme is the exploration of the characters' mental states. Since the original work deals with a character with a supposed psychopathic diary, fanfictions often dig deeper into how the characters' minds work. Another theme is relationships. They might expand on the friendships or rivalries in the show. And self - discovery is also common, as characters figure out who they really are in these new storylines.
Family love is a very common theme. Grandma is often shown as a figure full of love and care for her family members, especially the grandchildren. For example, in many stories, she cooks special meals for them or tells them bedtime stories.
Well, a common theme among these 5 animated horror stories is transformation. In 'The Nightmare Before Christmas', Jack Skellington transforms from being bored with Halloween to trying to take over Christmas. This theme of transformation can be seen in different ways in other stories too. Also, many of them have the theme of a character facing their fears, like Ichabod Crane facing the Headless Horseman in 'The Adventures of Ichabod and Mr. Toad'.
A common theme is hope. For example, in the stories where a character is resurrected, it gives hope to other characters. In 'The Lion King', Simba's 'encounter' with his resurrected - in - spirit father gives him hope to face his past and his future. Another theme is redemption. When a character is brought back, it often gives them a chance to right their wrongs. In some religious animated resurrection stories, like that of Jesus, his resurrection is about redeeming humanity.
Often, isolation is a theme. In 'Coraline', the main character feels isolated in her real life and that's part of what draws her to the other world, which then turns into a more sinister form of isolation. Also, fear is a big theme. These stories play on our fears of the unknown, the supernatural, and things that go bump in the night. In 'Paranorman', Norman has to face his fear of the ghosts to save his town. Dark animated stories also sometimes explore themes of redemption, like when a character has made bad choices but tries to make it right in the end.
Faith is also a common theme. In some animated resurrection stories, characters or other characters in the story have faith that the resurrected character will come back. In 'Pinocchio', Geppetto has faith that Pinocchio will become a real boy. This faith is part of what drives the story forward and is related to the resurrection - like transformation of Pinocchio from a wooden puppet to a real boy.
The theme of friendship also often appears. In 'Frozen', Elsa and Anna's relationship is key. Their sisterly love and the friends they make along the way, like Olaf, help them through their difficult times. Friendship gives characters support, motivation and the strength to face their problems.
Love and acceptance are common themes. These stories often focus on the journey of the characters in finding and being true to their love for another woman. For example, in many such stories, the characters have to overcome social prejudices within their fictional worlds.
