Sure are! Deadpool and Wolverine are definitely based on comics. They have rich storylines and character developments in the comic universe that have made them popular among fans.
Deadpool and Wolverine have a unique bond. While not always traditional friends, they have shared adventures and shown care for each other in their own way, despite their clashing personalities.
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.
Sabretooth could be a great villain. He has a long - standing feud with Wolverine, and adding Deadpool to the mix would make things even more chaotic. His savage nature and powerful fighting skills would pose a real threat to both of them.
Perhaps Mister Sinister. He has always been interested in mutants like Wolverine and could see Deadpool as a useful pawn or a nuisance in his grand schemes. He might try to manipulate the situation to his advantage, causing Deadpool and Wolverine to join forces against him.
Well, they both have a complex relationship. They are both mutants. Wolverine has his adamantium skeleton and healing factor. Deadpool also has a healing factor which makes their battles intense. They've crossed paths many times, sometimes as allies, sometimes as foes.
