Ancalagon could also be shown as more intelligent. Maybe in fanfic, he's not just a brute force but a master strategist, planning his moves carefully in the stories. He could outwit other characters through his cunning.
One way the Sharingan is portrayed differently in Naruto fanfics is through enhanced powers. In some fanfics, the Sharingan might have the ability to control time or space, which is not in the original series. This is to make the story more unique and engaging.
It could be made more intelligent. Instead of just being a summon for combat, it could be a strategic advisor to Naruto, guiding him in his decisions with its ancient knowledge.
In a fanfic, Naruto's teleportation jutsu could be different in terms of its range. Instead of having a set range, it could be based on his current chakra level. So, if he's full of chakra, he can teleport across the entire ninja world, but if he's low on chakra, it's only a short - distance teleport. Also, the jutsu could have a side effect. For instance, every time he teleports, he has a brief moment of disorientation. This would add an interesting element to battles and his overall use of the jutsu. Moreover, the teleportation could be linked to specific landmarks. He can only teleport to places he has a strong mental image of, like his home in Konoha or the training grounds where he practiced with Kakashi.
The relationship between Catwoman and Dick Grayson can be depicted as a detective - informant relationship. Catwoman has her ears to the ground in the criminal underworld and provides Dick with valuable information. Dick has to trust her, which is difficult for him given her past. Another portrayal could be that of a cultural exchange. Catwoman comes from a more street - smart and self - serving background, while Dick has the discipline and training of the Bat - family. They teach each other about their different ways of life. It could also be shown as a relationship of convenience. They both need something from each other at a particular moment. For example, Catwoman needs protection from a certain enemy, and Dick needs her help to infiltrate a criminal organization. So they form a temporary alliance that may or may not develop into something more.
Legendaries are usually shown as very powerful and having a lot of influence. Regular pokemon are more like the normal inhabitants. For example, a legendary might be able to control the weather in a fanfic, while a regular pokemon like Pikachu is just a cute and energetic electric - type that battles in normal tournaments.
Heirs in Harry Potter fanfic are often shown as having a special mission or purpose. They might be the only ones who can unlock a certain mystery or power. For example, an heir to Ravenclaw could be the only one who can solve the riddle to access a hidden library. Descendants, on the other hand, are more about the family connection. They may be part of a large family and have normal lives within the wizarding world, like the numerous descendants of the Black family who have different personalities and magical abilities but not all are heirs with a specific task.
Well, in some fanfics, Tom Riddle is portrayed as having a bit more humanity. Maybe he has a love interest that makes him question his dark ways. This is different from the books where he seems fully committed to the dark side from a young age.
In some Harry Potter fanfics, magical creatures like the werewolf might be portrayed more sympathetically. Instead of just being seen as dangerous during full moons, they could be shown as struggling with their condition. For example, a fanfic might focus on a werewolf trying to lead a normal life among wizards.
Adam Banks in Mighty Ducks fanfic can be depicted quite differently. One way is that he could be made into a mentor figure, which is different from his more equal - standing role in the original. Fanfic writers may show him guiding younger players, sharing his wisdom and experience. Another difference could be in his relationships with opponents. In fanfic, he might form unexpected friendships or rivalries with players from other teams, adding new layers to his character. Also, his personality might be exaggerated in some fanfic, either making him more confident or more shy depending on the writer's vision.
Their relationship could be portrayed as more of a partnership in the Clone Wars. Instead of just a romantic couple, they could be shown as two people with different skillsets who are equally important in achieving victory. For example, Padme could be more involved in the military strategy discussions with Anakin, using her political knowledge.
