There could be a power - hungry shinobi within Konoha itself. He is jealous of the bond between Naruto and Shikamaru and how they are getting stronger together. So, he tries to set them up, making it seem like they are betraying the village. He wants to break their friendship and take their place as a respected ninja in the village.
One possible plot could be that Naruto and Shikamaru go on a mission together in a forest. They face various challenges like tricky traps set by the enemy. Shikamaru uses his intelligence to figure out how to avoid the traps while Naruto uses his strength and determination to fight off any attackers. Their friendship deepens as they rely on each other's skills to complete the mission successfully.
It could be a rogue ninja who has a vendetta against cats for some strange reason. This ninja might try to capture Tora to use it as bait for Naruto or just because he wants to harm it. So, he becomes the main obstacle in Naruto and Tora's friendship.
There could be an internal antagonist within Konoha as well. Maybe a jealous ninja who has always had a crush on Shikamaru or envied Ino's skills. This person could spread false rumors about Ino's pregnancy, causing unnecessary stress and drama for the couple. They might try to drive a wedge between Shikamaru and Ino during this vulnerable time.
The plot might also focus on their daily lives in the village. They could be shown hanging out, sharing their dreams and fears. Naruto might talk about his goal to become Hokage and Shikamaru could share his concerns about the responsibilities that come with being in the shinobi world. They could also get into friendly competitions like a race across the rooftops of the village, with Naruto using his speed and Shikamaru using his intelligence to find shortcuts.
It could be a jealous student. Maybe there's a Gryffindor who is envious of Creevey's friendship with Harry. This student might spread rumors about Creevey, saying that he's only using Harry for his fame. This causes some tension between Harry and Creevey at first, but they eventually figure out the truth and strengthen their bond in the face of this false accusation.
Choji can be an interesting addition. He has a long - standing friendship with Shikamaru and his unique eating - based jutsu can be a valuable asset in battles in the fanfiction. With Ino, he can provide some comical relief as well as a different type of fighting style. Also, Kakashi could be paired with them. His vast experience and diverse jutsu knowledge can guide Ino, Shikamaru and the others, and his laid - back but serious attitude can be a great influence on the group.
It should also have an engaging plot. Maybe it involves a mystery that only they can solve together because of Naruto's ability to find clues in unexpected ways and Shikamaru's ability to piece them together. The setting should be well - described, whether it's the streets of Konoha or a far - off land they travel to. And the dialogue between them should be natural, like real friends talking, with Naruto's exuberant speech and Shikamaru's more measured responses.
One great 'Naruto Shikamaru fanfiction' is 'A Different Path'. It offers a unique take on Shikamaru's character development, showing his growth in ways not fully explored in the original series. The plot is engaging and the author does a wonderful job of staying true to the Naruto universe while adding their own creative twists.
It could be Hades. He might not like the idea of Percy, a son of Poseidon, being friends with Apollo. Hades could see it as a threat to his own power or plans in the underworld.
It could be Draco Malfoy. Since Harry and Ron are not friends, Draco could take advantage of their weakened state. He might try to turn them against each other even more, perhaps by spreading false information about one to the other. He could also try to isolate Harry from the Gryffindor group since Ron is no longer on his side, making Harry an easier target for his bullying.
