The 'alien covenant graphic novel' is mainly about the events and stories within the Alien Covenant universe. It might explore the crew's journey, their encounters with the aliens, and the overall dark and menacing atmosphere of that world.
I'm not entirely sure, but it could include characters related to the Engineers as they are crucial to the origins. Maybe some scientists or explorers who are trying to uncover the secrets of the alien origins.
Typically, the main characters would include the members of the Covenant crew. There's the captain and other important crew members who are on the mission.
Another great one is 'Alien: Sea of Sorrows'. It delves deeper into the xenomorph lore and the universe they inhabit. It has a complex plot that involves different groups of people trying to deal with the xenomorph threat in a unique setting. The descriptions of the xenomorphs are vivid and terrifying.
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.
The Covenant is not a true story. Usually, such works are crafted to entertain and engage the audience through imaginative plots and characters rather than being rooted in reality.
It's hard to say for sure if the story of the covenant is true. There are various factors to consider, such as the source of the story and the context in which it emerged.
