One possible fanfiction could involve Itachi returning from the dead in some way. He decides to train Naruto to help him master new skills. Itachi might teach Naruto some of the more advanced Uchiha techniques, like advanced fire - style jutsu or the sharingan - related skills he has. Naruto, with his own vast chakra reserves and unique abilities, would then combine these new teachings with his own Rasengan - based attacks. This could lead to some really cool battle scenes in the fanfiction where Naruto surprises his enemies with new moves.
In many Fairy Tail fanfictions, the battle between Natsu and Acnologia is often depicted as extremely epic. Natsu's fiery determination and his unique dragon - slayer magic make for an interesting contrast against Acnologia's overwhelming power. Some fanfictions might have Natsu discover new forms or powers in order to stand a chance against the fearsome Acnologia.
Lucy might also be an ally. She has her celestial spirits that could be a great help. For example, some of the spirits like Leo could be very powerful in combat against the dragons. Also, Erza would be a great addition. With her various armors and combat skills, she could hold off a large number of dragons while Natsu focuses on the more powerful ones among the 10000.
Well, the occurrence of a timeskip in a manga can be quite unpredictable. It usually happens when the author wants to introduce significant changes in the story or characters' situations. But without specifying the manga, it's impossible to give a precise answer.
Itachi could train Naruto to better understand the nature of chakra. He might show Naruto how to sense and manipulate chakra in ways he hadn't considered before. For example, Itachi could teach Naruto how to infuse his Rasengan with different elemental chakra more effectively. This would give Naruto an edge in combat against stronger opponents. Also, Itachi could train Naruto in stealth and infiltration techniques, skills that Naruto has not really focused on before.
Well, perhaps Natsu uses his powerful fire magic to take on the dragons one by one. He might start by finding a strategic location to face them, like on top of a large mountain where he has a better view. Then, he'd use his signature moves like Fire Dragon's Roar to blast groups of dragons at a time.
