In a Naruto fanfiction, acid blood could be a key factor in a mystery plot. Maybe there are disappearances in a village and it turns out to be related to someone with acid blood. This would make the story more complex as characters try to solve the mystery while also dealing with the danger that acid blood poses.
It could be a sign of a major turning point. If Naruto starts coughing up blood, it might signal that he's in a really dangerous situation and needs to find a way to get out of it fast. This can lead to new adventures as he searches for a cure or a way to regain his strength.
His blood control ability might also create new alliances or enemies. Allies could see his power as a great asset and join him, while enemies might fear his newfound ability and target him more aggressively. In the context of the fanfic, this would add more twists and turns to the plot. Maybe some characters who were neutral before would now side with Naruto because of his blood control, or some of his old enemies would form stronger alliances against him.
Divinity can greatly affect the plot. If a character has divine powers, it can change the power balance in the story. For example, if Sasuke gains divine powers in a fanfic, his battles with Naruto will be much different. It can also introduce new conflicts, like other characters fearing or trying to control the divine - powered character.
One interesting concept could be the origin of the acid blood. Maybe it's a result of some forbidden jutsu experiment gone wrong. It could add a new and dangerous element to the Naruto universe.
His black blood could make his healing abilities different. Maybe it heals faster but at a cost, like using up a lot of his energy. Or it could have a unique way of repairing damage, like creating a black - colored chakra shield during the healing process.
It can create a lot of twists. For instance, if a main character has the 'Gift of Foresight', they can avoid traps that were set for them, changing the expected flow of the story.
Well, in many fanfictions, Sakura's jealousy can be a major plot - driving force. For example, it can lead to her taking actions she wouldn't normally do, like confronting Naruto or the person she's jealous of. This can create conflict and tension in the story.
It can create a lot of twists. For example, if a character with the shapeshifter bloodline is initially thought to be a weakling but then reveals their power, it can turn the whole plot around. They could infiltrate enemy groups by shapeshifting, which would be a great advantage for their side.
The magnet bloodline can also affect the plot by changing the character's role within their ninja team. Instead of being a regular member, they might become the key strategist or defender due to their unique ability to manipulate magnetic forces. This can lead to different team dynamics and mission outcomes. For instance, in one fanfic, the character with the magnet bloodline was able to disarm an entire enemy group by attracting all their metal weapons.
An irresistible force can completely change the plot. If it's a new and powerful enemy, it can create a sense of danger and urgency. The characters will have to find ways to either defeat it or co - exist with it. For example, if there's a powerful demon that suddenly appears, the ninjas will have to stop their normal activities and focus on dealing with this threat.
