Sure, Deadpool has been part of the X-Men on and off. His relationship with them is complex and can change depending on the comic arc. Sometimes he's a full member, sometimes he's just associated with them for a specific mission or story.
There is a loose link. The version of Deadpool in Wolverine Origins provided a starting point, but the standalone Deadpool movies developed his character and story in a more distinct and expanded way, deviating from the initial portrayal to create a more focused and engaging narrative.
It's a bit of a mixed bag. While there's a link, the portrayal of Deadpool in Wolverine Origins doesn't fully align with his later, more developed storyline. Some elements were changed or not fully explored.
In 'X Men Origins Story', Wolverine is the primary character. His complex personality and his search for his past are what drive the story forward. His brother Victor Creed, also known as Sabretooth, is an important character as well. He has a different view on their mutant abilities compared to Wolverine. Another main character is William Stryker. He is the mastermind behind many of the events in the movie, especially the Weapon X project which has a huge impact on Wolverine's life. There are also other mutants that make appearances, but these three are the most central to the plot.
The story mainly focuses on Wolverine's origin. It shows his early life, his relationship with his brother Victor Creed. Wolverine gets involved in various military operations and experiments. He endures a lot of pain and trauma during these experiences which ultimately lead to his transformation into the Wolverine we know, with his adamantium skeleton and retractable claws.
Deadpool and Wolverine are a great pair. Wolverine's serious and no - nonsense attitude contrasts perfectly with Deadpool's zany and irreverent personality. They could have some epic battles where Deadpool's constant chatter drives Wolverine crazy, but also some moments where they realize they're not so different. Another good pair would be Deadpool and Rogue. Rogue's power - absorption ability could lead to some interesting situations when she tries to touch Deadpool, and his unpredictable nature would keep her on her toes.
Well, in fanfiction where Deadpool joins the X - Men, it could change the entire dynamic. Deadpool doesn't really follow the same moral code as the X - Men. He might go after enemies in a much more brutal way, which could cause some internal conflict within the team. On the plus side, his popularity and connections in the seedy underworld could provide the X - Men with valuable intel. His presence would also likely attract a whole new set of villains who want to take on the 'new' X - Men. And his self - awareness and ability to interact with the narrative itself could make for some really interesting and comical storylines.
There isn't a prominent 'moon story' in X - Men Origins Wolverine that I can recall. The movie mainly delved into his past, like his time with Victor Creed, his participation in various military operations, and how he got his adamantium skeleton. It was more about earthly events and his personal growth as a mutant rather than having a moon - related plot.
