His plant - like nature can be incorporated in various ways. He could use his connection to the plant world to set up traps or communicate over long distances. In a fanfic, he might use the roots of plants to spy on the characters or to send secret messages. He could also create a kind of 'plant network' that only he can access, which adds an element of mystery and danger to the story. This would make the story more engaging as the characters have to figure out how to deal with this unique threat.
Zetsu's ability to split into two parts can be used to create interesting plot devices. For example, one part of Zetsu could be captured by the protagonists, while the other part goes on to execute a different part of the villain's plan.
Well, one way could be in their physical abilities. Maybe in the fanfic, Naruto is shown to have some of Zetsu's stealthy movement skills, like being able to blend into the environment in a similar way. Another similarity could be in their connection to nature. Zetsu has a strong link to the plant - like aspects of nature, and Naruto's chakra might be shown to have a similar kind of connection in the fanfic.
When Naruto absorbs Zetsu in the fanfiction, it could impact his mental state as well. Zetsu has been involved in many dark and devious plans. Naruto might have to struggle with the knowledge and influence of those. However, on the positive side, Naruto could use Zetsu's ability to communicate with the plants and gather intelligence from the natural world. This would expand his range of information sources and give him an edge in strategic planning during battles.
In some fanfics, Naruto might have Zetsu's ability to blend into the environment or be as stealthy as him.
Naruto's ability to use shadow clones could be really useful. He could send out clones to scout the Digimon world, looking for resources or threats. His Rasengan could also be adapted. Maybe he could combine it with a Digimon's energy attack for a more powerful blow. Also, his speed and agility from being a ninja would give him an edge in battles against Digimon.
Zetsu could be a mysterious informant in a Naruto fanfic. He could be lurking in the shadows, gathering information for either the good guys or the bad guys and providing crucial intelligence that changes the course of events in the story.
The fanfic might explore new aspects of Naruto's character by comparing him to Zetsu. It could show different sides of Naruto that we haven't seen before, like his more devious or strategic side if he takes on some of Zetsu's traits. This exploration of character depth can be really engaging for readers.
Naruto's Rasengan could be a powerful weapon. He could use it to smash into the Xenomorphs' hard exoskeletons. Sasuke's Chidori might be able to pierce through their bodies. And Sakura's super strength could be used to physically overpower the Xenomorphs if she can get close enough. Shikamaru's intelligence would also come in handy for devising strategies to outwit the Xenomorphs.
His chakra control might be affected by the different magical energies in the DxD world. Maybe his chakra could interact with the devil or angelic powers in unexpected ways. For example, his Rasengan could gain new properties if combined with devilish power. His shadow clones might also be able to do things like sense magical auras, which they couldn't do in the Naruto world.
He may develop a more calculating side. Black Zetsu is all about manipulation. Naruto could start thinking several steps ahead in a more devious way. For example, he might start using people's weaknesses against them, which is completely against his original nature. This change in personality would likely cause a rift between him and his friends who know him as the always - honest and straightforward Naruto.
Naruto's Rasengan could be adapted as a high - powered energy attack for an Armored Core mech. Just like in the Naruto series, it could be a concentrated and powerful blast. His ability to quickly learn new jutsus could translate to the mech pilot being able to quickly adapt to new weapon systems or combat strategies in the Armored Core world.
