It's hard to give a precise number. Xenomorph comics have been produced by multiple companies over the years, and new ones may still be coming out. You could check with comic bookstores or online comic platforms for the latest information.
When writing a xenomorph pregnant fanfiction, think about the setting. Is it on a spaceship? A desolate planet? The setting can add to the atmosphere. You also need to consider the emotions of the pregnant character. They'll likely be filled with horror, confusion, and a sense of impending doom. Try to show these emotions through their actions and thoughts. For the plot, you could have the character team up with others who are also in danger from the xenomorphs, or they could be alone and have to face it all by themselves.
Writing xenomorph fan fiction can sometimes be legal. If you're not profiting and not causing harm to the original work's reputation or market, there's a chance it's within the bounds of the law. But always err on the side of caution and respect copyright.
The unique elements often include the combination of Naruto's ninja abilities like jutsu and chakra control with the terrifying nature of Xenomorphs. For example, Naruto might use his Rasengan against a Xenomorph, which is a very cool visual.
One idea could be a story where a human child is found by a xenomorph in a post - apocalyptic world. The xenomorph, instead of attacking, shows an unusual curiosity towards the child. Maybe it's because the child has a unique scent or some kind of energy that the xenomorph has never encountered before.
The novelty. It's not a common concept to have a love story involving a xenomorph. It's so different from traditional love stories that it grabs people's attention.
One great Xenomorph female fanfiction could be one that focuses on her survival instincts in an alien environment. It might show how she uses her unique abilities to outwit other threats. Another could be a story where she forms an unlikely alliance with a human, leading to a series of adventures where they learn from each other.
Maybe the Xenomorph Queen herself could be the main antagonist. She is intelligent and powerful. She sees Naruto's world as a new place to colonize and sends her Xenomorph minions to attack. Naruto has to find a way to stop her before she spreads too many eggs and creates an unstoppable army.
One possible plot could be that Naruto discovers a hidden Xenomorph lair in the Hidden Leaf Village. He uses his ninja skills to try and figure out how the Xenomorphs got there and what their purpose is. Maybe he has to team up with some of his friends, like Sasuke, to fight off the Xenomorphs before they take over the village.
A simple way could be to have a human character who is a botanist studying strange plants on a planet infested with Xenomorphs. The botanist discovers a lemon - like plant that has properties which can either repel or attract Xenomorphs. This discovery then becomes the central point of the story as the human tries to use it to survive among the Xenomorphs.
