There might be some fanfics that involve these characters in a non - adult way. You can start by looking on fanfic platforms like Archive of Our Own and filter for the appropriate ratings. Some writers create stories that focus on the friendship or team - up aspects of Deadpool, Spider - Man and explore themes related to the 'cancer' aspect in a more character - development and story - driven manner rather than something inappropriate.
Fanfiction.net might also have some. However, the quality and content can vary a great deal. You'll need to use the search function and look for stories that involve these specific elements. But again, be cautious as not all stories may be well - written or appropriate.
Deadpool became Deadpool through a series of complex and sometimes convoluted events in the comics. He was originally a mercenary named Wade Wilson, who underwent experimental treatments that gave him his unique powers and personality.
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.
