One common theme is Naruto highlighting Sasuke's pride. Naruto often uses Sasuke's over - the - top pride as a target for his roasts. For example, he might make fun of how Sasuke always thinks he's better than everyone else in terms of skills.
In some 'naruto roasts sakura fanfiction', Naruto might roast Sakura about her always chasing Sasuke. For example, he could say something like 'You're so blinded by Sasuke that you forget about the real things around you.'
Another great one is 'Naruto's Epic Roast of Sasuke'. In this fanfiction, Naruto roasts Sasuke during a training session. He makes fun of Sasuke's brooding nature and how he always tries to act so cool. Naruto uses his own experiences and the times they've spent together to come up with some really cutting - edge roasts that leave Sasuke both angry and a bit embarrassed.
In such fanfiction, Sakura might be depicted as more alluring and perhaps more bold in her interactions with Madara. Madara could be shown as having a certain charm that draws Sakura to him.
Well, it could be through his powerful ninja techniques. Maybe he uses his Sharingan to paralyze Sakura, or perhaps he physically restrains her with his great strength. In fanfictions, there are many creative ways for such a scenario to play out.
Madara could also save Naruto by using his knowledge of the ninja world. Maybe he has some inside information about a plot against Naruto and he intervenes in time to stop it. He might have discovered a secret plan by an enemy group and takes action to keep Naruto out of harm's way. This could involve manipulating events behind the scenes or directly confronting the threat.
Naruto is often paired with Madara in some fanfictions. Their interactions can be really intense, as Naruto tries to either convince Madara to change his ways or fight against his reborn form.
Perhaps he sees her as a threat. Sakura is a skilled kunoichi, and Madara may want to prevent her from interfering in his plans. So he restrains her to keep her out of the way.
