Perhaps it's part of a story or a symbolic image. Maybe it represents a child's fear or a dangerous situation in a fictional setting. It's hard to say for sure without more context.
Deadpool is the central figure for sure. The baby is another main character as the story revolves around their relationship. There may be other characters like Vanessa if the fanfiction decides to bring her into the story. She could be either a co - parent or have some influence on how Deadpool raises the baby.
Well, in some 'deadpool has a baby fanfiction', there could be really interesting plots. For example, Deadpool might struggle to adapt to fatherhood while still being his crazy self. He could try to teach the baby all his unorthodox fighting skills or his unique sense of humor. The baby might also inherit some of Deadpool's abilities, which could lead to all sorts of comical and action - packed situations as Deadpool tries to keep the baby safe and out of trouble.
In fanfiction, the author might be using this as a creative device to add humor and character to their interactions. Deadpool calling Spider - Man 'baby boy' could also be a way to show Deadpool's dominance in their relationship. He's a more chaotic and unpredictable character, and by using this term, he's asserting his own brand of crazy over Spider - Man.
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.
One scenario could be during a fight. Deadpool is taunting Spider - Man while they're trading blows, shouting 'baby boy' to throw him off his game. Another might be when they're teamed up and Deadpool is trying to give Spider - Man some unorthodox advice, starting with 'listen here, baby boy'.
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.
