The character of Aku could be developed in a 'pregnant Aku in Samurai Jack fanfiction' by exploring how he interacts with the world around him differently. He may become more reclusive as he doesn't want others to see his 'weak' state. Or he could become more aggressive in trying to protect his pregnancy, which would be a new aspect of his character. Also, his relationship with his own power might change. Maybe he has to find new ways to use his magic that don't harm the unborn, which would force him to grow and adapt in ways he hasn't before.
Well, a plot could revolve around Aku trying to keep his pregnancy a secret from Samurai Jack. He might be worried that Jack would use this new situation to his advantage. And then there could be a sub - plot about Aku having strange cravings that lead him to unexpected places in the world of the fanfiction, causing chaos in different ways.
Not very accurate. The movie exaggerated some parts. For example, the samurai's unwavering loyalty as shown was a bit overdone. In real life, there were internal conflicts among samurai too.
We can recommend a few swordsman and samurai novels.
As for swordsmanship novels, we can recommend Mr. Jin Yong's works, such as The Return of the Condor Heroes, The Eight Dragons, and The Smiling Proud Jianghu. These novels used Wuxia as the theme, telling the heroic stories of the heroes and the grudges of the Jianghu.
For Japanese samurai novels, there was a recommended work called " The Guards at Dusk." The theme of the novel was the Bushido spirit, which described the Japanese's forbearance, reticence, competitiveness, and sense of mission. The other recommended book was " I Was a Sword Hero in Ancient Japan." It told the story of a protagonist who traveled to ancient Japan. He became a sword hero in this era and fought against all kinds of powerful people and dignitaries.
In general, swordsman novels and samurai novels had their own characteristics and charms. The readers could choose the works that suited them according to their interests.
Well, in terms of weaponry, in the movie some weapons were shown in a more glorified way. Fact is, samurai weapons were highly practical but not as flashy as in the fiction part of the movie. For example, the katana was a tool for battle, not just a shiny object for show. And the samurai's code of honor, Bushido, was real but the movie might have over - emphasized some aspects for the sake of drama.
I'm not sure who Aku specifically is. Aku could be a person with a great imagination who tells all kinds of stories, like adventure stories, fairy tales or even true - life stories.
It could be someone from the Naruto universe who doesn't like Naruto's newfound fascination with Aku. For example, Danzo might see Naruto's interest in Aku as a threat to the stability of the village and try to stop Naruto from further exploring Aku - related things. So, Danzo could be the main antagonist in this case.
One idea could be a crossover where Aku accidentally opens a portal to the Naruto universe. Naruto, being the curious and brave ninja he is, decides to explore Aku's world. They could start off as enemies, but gradually come to understand each other's motives and end up teaming up against a greater evil that threatens both of their worlds.
