His arrogance could still be there but in a different way. Instead of flaunting his dragon superiority, he might show off his human skills or knowledge. He could be a bit of a know - it - all, but also be more approachable to others in a human form.
He might become more empathetic. As a dragon, he was all about power and domination. But as a human, he could start to feel the pain and joy of others, which would soften his once - harsh personality.
In a fanfiction, Alduin in human form could be a lost soul. He has lost his dragon power but still retains his pride. He could be searching for a way to regain his former status. Along the way, he meets a young mage who senses his true nature and tries to either help or stop him, depending on the writer's take.
His loyalty would still be a big part of his personality, but it could be expressed differently. Instead of just following Natsu around like he did as an Exceed, he might try to support Natsu in more strategic ways as a human, using his newfound human intelligence.
He might become more empathetic in his human form. Since humans have a wide range of emotions and experiences, Kurama could pick up on these and become more in tune with the feelings of others compared to when he was just a fox demon.
In a fanfiction with a berserk form, Deku's personality would experience a significant shift. He would become more primal in nature. His usual self - restraint and careful consideration of his actions would disappear. He might act on instinct more, like a wild animal lashing out at threats. His friendly and approachable demeanor would be replaced with a menacing presence. He could even have moments of confusion when he comes out of the berserk state, as if he doesn't fully remember or understand the actions he took while in that form. But over time, as he learns to control this new side of himself, he might be able to find a balance between his normal self and the berserk - influenced personality.
He would probably be more impulsive as a human. Since he was always about speed as a car, he might have a hard time slowing down and thinking things through. For example, in making decisions about his racing career or personal relationships.
He might become more vulnerable. As a monster, Godzilla was powerful and feared, but as a human, he would have to face the fact that he could be easily hurt. This could make him more cautious and less aggressive.
No, it's not likely to be popular. Skyrim has a large and diverse fan base, but most fans are interested in the more canonical aspects of the game. A female Alduin is a very unorthodox take, and adding 'lemon' content further restricts its appeal. Most people who write and read Skyrim fanfiction are more into stories that expand on the existing storylines, character development, and the overall fantasy world of Skyrim without delving into such out - of - the - ordinary and potentially inappropriate combinations.
One great Skyrim female Alduin fanfiction is 'The Alduin's Daughter'. It tells a story of a female character who has a special connection to Alduin. The story is full of adventure and mystery as she tries to understand her role in relation to the great dragon.
Jack's personality would likely become more innocent and naive. As a baby pooka, he might be more curious about the world around him without the usual wariness he has as his normal self. He could be more easily frightened by things that he wouldn't normally be afraid of as an older Jack. Also, he might be more impulsive in his actions, just going for things that catch his eye without thinking much about the consequences.
To create a compelling female Alduin character, think about her motives. She might not want to be the villain she is made out to be. So, her actions could be driven by a desire to break free from the expectations placed on her. Her relationships also matter. If she has a bond with other dragons, it could be different from the male - dominated dragon society we usually think of. She could be more empathetic towards the mortals of Skyrim, which would make her a complex and interesting character. Also, her voice, both literally and figuratively, should be strong and distinct. Her dialogue should reflect her internal struggles and her new perspective on her role.
