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.
Since I have no knowledge of this particular 'Armada Novel', I can't tell you the author. However, if you have access to a bookstore or an online book retailer, you could look up the book there. They usually have information about the author, publication date, and a brief synopsis of the book.
The 'Armada Novel' could be about various things. It might be a science - fiction story set in a fictional Armada, perhaps involving spaceships in a fleet and their adventures, like battles against alien species or exploration of new galaxies.
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.
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.
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.
She could be a secret agent in the Transformer Armada world. Mulan uses her combat skills and quick thinking to help the Autobots in their fight against the Decepticons. Maybe she discovers a hidden power within herself that can communicate with the Transformers on a deeper level.
I'm not sure who specifically wrote the lyrics for a song titled 'lirik never ending story'. It could be written by the songwriter associated with a particular musical version of 'The Never Ending Story'.
Armada reviews of novels often offer different perspectives. They could praise a novel for its unique concept. For instance, a science - fiction novel might be lauded for its imaginative world - building. On the other hand, a review might criticize a novel for being too slow - paced. It might also compare the novel to others in the same genre, stating whether it stands out or blends in too much.
