One common theme is power adaptation. Since Kakashi is from the ANBU, he has a certain set of skills. In crossovers, he has to adjust these skills to fit the new world he's in. For example, if he crosses into a world with magic, he might need to figure out how his ninja techniques work with the new magic system.
Friendship and alliances are also common themes. In the new crossover worlds, Kakashi often has to make new friends or form alliances. Sometimes these are with characters who are very different from those in the Naruto world. This leads to some interesting character interactions and development. For example, he might team up with a character who has a completely different set of values but they learn from each other over time.
One common theme is loyalty. In the ANBU, loyalty to the village is of utmost importance. Fanfictions often explore how Naruto and Kakashi uphold or struggle with this loyalty. For example, they might face a situation where their loyalty to each other conflicts with their loyalty to the village.
A prevalent theme is sacrifice. Given the dangerous nature of Anbu missions, there are often situations where one of them has to make a sacrifice for the other or for the greater good of the village. This theme adds a lot of depth and drama to the fanfictions. It also shows the strength of their relationship as they are willing to put themselves in harm's way for each other.
One common theme is redemption. Since Kakashi has a lot of regrets in his life, in time - travel fanfics, he often tries to make up for his past mistakes. For example, he might try to save his comrades who died in the original timeline.
One common theme is the clash of cultures. Kakashi comes from the ninja world of Naruto, and when he enters the Bleach universe, there's a contrast between the two. For example, the way they handle combat and the hierarchies in their respective worlds.
There's also 'Kakashi and the Time - Travel Crossover'. In this fanfiction, Kakashi gets sent to a different universe where he has to use his ANBU training to survive. It's really interesting to see how he adapts to the new rules and enemies in that world. The author does a great job of blending the different elements.
Well, Kakashi could train Naruto in combat skills specific to ANBU missions. This would include more lethal and precise attacks. He might also teach Naruto how to use different types of weapons that are common in ANBU operations. Maybe Kakashi would set up mock battles where Naruto has to face multiple opponents at once, just like in real ANBU scenarios.
Power and its abuse is also a common theme. The Anbu has a lot of power, and an OC might be faced with situations where they see this power being misused. Then there's the theme of identity. An OC in the Anbu may struggle with their identity as a ninja who has to do some morally gray things for the sake of the village. This exploration of identity makes for some really interesting 'oc anbu fanfiction' stories.
Well, there are quite a few common themes in Kakashi fanfiction. His mysterious personality is a big draw, so a lot of stories try to delve deeper into what makes him tick. Romance is also a theme, whether it's a relationship with another ninja in the village or someone from a different place. Additionally, his skills as a fighter and strategist are often highlighted in action - packed fanfiction stories. There are also some fanfictions that explore his relationship with the Hokage and his place within the village hierarchy.
In Anbu fanfiction, Kakashi is often depicted as a highly skilled and mysterious figure. His past experiences in Anbu shape his character, making him more reserved and calculative. Sakura, on the other hand, might be shown as growing in strength and independence while in the Anbu setting. She could be learning from Kakashi's expertise and trying to prove herself in this more dangerous and secretive organization.
Their relationship in Anbu fanfiction can be really interesting. It could be a relationship of mutual respect. Kakashi respects Sakura's determination and Sakura respects Kakashi's skills and experience. They might work together on various Anbu missions, with Kakashi leading and Sakura following his lead at first. But as time goes on, Sakura could start to contribute more equally.
