Power and its consequences. The poison bloodline often gives the characters a very powerful and dangerous ability. So, a common theme is how they deal with that power, whether they use it for good or are tempted to use it for evil.
Power and its control is another theme. The Poison Ivy bloodline brings unique powers, like poison - based attacks or the ability to manipulate plants. Fanfictions usually explore how characters learn to control these powers and not let them get out of hand. For instance, a character might initially struggle with the toxicity of their attacks harming allies, but then learn to fine - tune it. Also, the theme of identity is prevalent. Characters with this bloodline have to figure out where they fit in the Naruto world, whether they should embrace their different bloodline or try to assimilate into the more common ninja clans.
It could completely change the dynamics of his powers and his journey. Maybe he'd have an easier time mastering jutsu or face new challenges related to his unique bloodline.
There's also 'The Venomous Bloodline's Ascent'. In this fanfiction, the protagonist with a poison bloodline has to fight against the discrimination within the ninja villages. It's an interesting take on how unique bloodlines can be both a strength and a source of prejudice. It shows a lot of character development as the protagonist tries to prove their worth.
I'm not sure about the exact name, but some of these fanfictions explore how the Poison Ivy bloodline abilities would be perceived in the Naruto setting. For example, the ability to control and produce poison could be a huge advantage or a source of fear among the ninja. Some fanfics might focus on a character who has this bloodline trying to hide it, while others could be about them flaunting it and using it to rise to power.

Well, he could use the power to control plants during battles. He might be able to create thick vines to trap his enemies or make plants grow rapidly to block attacks. It would add a whole new dimension to his combat abilities.
One implication is that he becomes a more formidable opponent in battles. Enemies who rely on poison - tipped weapons or poison - based jutsus would be at a disadvantage against him.
There are also fanfictions where a bloodline is created through some sort of experimental jutsu. For example, a bloodline that allows the user to transform into different elements at will. This would give the character an edge in combat as they could adapt to any situation by changing their form.
In some fanfics, Naruto absorbs the bloodline through a special jutsu. For example, he might find an ancient scroll that contains a jutsu allowing him to transfer and absorb the genetic traits related to a bloodline.
Some of his friends might be in awe of him. They could see him as even more of a hero or someone to look up to. For example, Konohamaru would probably be even more excited to train with Naruto and learn from him. However, some friends might also be a bit jealous of his new powers. Sakura might initially be a bit wary, but she would also be concerned about how Naruto is handling this new power.
