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 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.
Naruto's outgoing and boisterous personality would make Deku more confident. He would probably be more upfront and less shy. Naruto's strong sense of justice would also intensify Deku's already existing desire to help others.
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.
It could look like Deku with bulging, blood - red muscles and his hair standing on end, like a wild, enraged beast. His eyes might glow with an unholy intensity, and his costume could be tattered and shredded from the sudden transformation. There could be a dark, menacing aura surrounding him as he taps into this berserk power.
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.
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 female form, Naruto might become more sensitive to certain things. For example, she could be more aware of how she is perceived by others in the swimsuit. Her boldness might still be there but could be expressed in a different way, like being more sassy. However, her core values of loyalty and determination to protect the village would remain the same.
Gohan could become more of a leader. With the power of Super Saiyan 5, he would be one of the most powerful beings in the universe. Other Z - fighters might look to him for guidance and leadership. This could bring out a more assertive side of his personality. He would need to step up and make tough decisions for the greater good, which would shape his personality in a more authoritative way.
His personality would change in several ways. For one, he'd have to be more cautious. Obito was involved in a lot of secretive and dangerous operations. Naruto would have to adapt to this new level of secrecy. Also, he might become more brooding as he tries to understand Obito's darker motives in the original story. But ultimately, his strong belief in friendship and his never - give - up attitude would still be there, and he'd use them to make different choices than Obito did.
His sense of justice could be affected. While Naruto has always been about protecting the village and his friends, the Dracula bloodline might introduce a more self - centered aspect. He might be more concerned about protecting his own existence as a half - vampire or using his powers for his own gain rather than for the greater good. However, he would also likely struggle with this internal conflict as his original values would still be there, fighting against the darker influences of the Dracula bloodline.
