Action is also a prevalent theme. Given their superhero status, fanfics often feature them in battles against various foes. There are also themes of acceptance. Colossus accepting Deadpool for who he is, flaws and all, is often explored in these fanfics.
The main characters are obviously Deadpool and Colossus. Deadpool is the wisecracking, anti - hero known for his regenerative abilities and off - the - wall humor. Colossus is the strong, metal - skinned mutant with a more traditional heroic sense.
Redemption can also be a theme. Sometimes Deadpool is on a journey of self - improvement, and Colossus is there to support him. This can be seen in fanfics where Deadpool tries to become a better hero, with Colossus as his guiding light.
The theme of growth is also prevalent. Deadpool can grow in terms of becoming more empathetic through his relationship with Colossus, while Colossus can become more flexible. In fanfictions, we often see them change and develop as characters as a result of their interactions, like Deadpool learning to be more selfless in some stories.
There's also 'Colossus and Deadpool: Unlikely Allies'. This fanfic focuses on a mission where Colossus and Deadpool have to work together against a powerful new villain. It's full of action scenes and some really humorous dialogues between the two characters.
In the 'Deadpool' movies and comics, there are some really memorable moments between them. These moments give fanfic writers a lot of material to work with. Writers can take those small interactions and build entire storylines around them. They can also play with the idea of Deadpool trying to corrupt Colossus' good - boy image or Colossus trying to reform Deadpool. All these possibilities make this type of fanfic very appealing to fans of the characters.
