Well, consider a situation where an old enemy of Deadpool's teams up with a new threat against the Avengers. Deadpool, initially on the sidelines, realizes that his own survival depends on the Avengers' success. So, he decides to offer his 'help'. However, his methods are so unorthodox that the Avengers are constantly second - guessing whether to trust him or not. This creates a lot of tension and comical moments within the story as they try to work together against the common foes.
One idea could be Deadpool trying to join the Avengers in his own wacky way. He might show up unannounced at the Avengers Tower, causing chaos and confusion among the team members. Another plot could involve Deadpool being hired by a villain to disrupt the Avengers, but then he has a change of heart halfway through. Or perhaps Deadpool accidentally travels to an alternate universe where the Avengers are very different, and he has to find a way to get back while also dealing with this strange new team.
One idea could be Deadpool trying to join the Avengers in his own zany way. He might show up at the Avengers' headquarters with a bunch of crazy gadgets and a self - made resume full of his 'accomplishments' that are half - heroic and half - insane.
A possible plot could be that the Avengers are on a mission to retrieve a powerful artifact. Deadpool, who has his own reasons for wanting the artifact, also shows up at the same place. Instead of fighting each other, they form a temporary alliance. Deadpool's knowledge of the underworld and his unpredictable fighting style, combined with the Avengers' superpowers, help them overcome the various traps and enemies guarding the artifact. However, after getting the artifact, they have to decide what to do with it, which leads to some internal conflict among the group and more hilarity with Deadpool's input.
One idea could be Deadpool trying to join the Avengers but constantly annoying them with his non - stop chatter and crazy antics. For example, he could keep interrupting their strategy meetings with his own hare - brained plans.
One idea could be that they team up to take on a new super - villain who has the ability to manipulate time. Deadpool's unpredictability and Spiderman's quick thinking would make for an exciting combination in this scenario.
One idea could be Deadpool getting dropped into the RWBY universe and thinking it's some sort of crazy new mission. He starts trying to team up with the RWBY girls, but his chaotic nature constantly causes misunderstandings. For example, he might mistake a Grimm for one of his usual foes and go after it in his own wacky way, much to the confusion of the RWBY characters.
One idea could be that they are both transported to an alternate dimension. In this dimension, all the rules are different. Deadpool's healing factor doesn't work as well, and Harley Quinn's usual weapons are useless. They have to rely on each other's skills and knowledge to find a way back home. Along the way, they meet strange versions of their friends and enemies, which adds to the hilarity and confusion.
One idea could be that Deadpool and Spider - Man team up to take on a new supervillain who has the ability to manipulate time. Spider - Man uses his quick thinking and acrobatic skills, while Deadpool's unorthodox fighting style and regeneration ability keep them in the fight.
A plot could involve the Avengers trying to understand the Flash's powers. Tony Stark might be especially intrigued and try to create technology to mimic the speed force. Meanwhile, the Flash could be in awe of the Avengers' different abilities and learn new ways to use his speed from them. For example, he could learn combat strategies from Captain America or how to better control his powers from Doctor Strange. And then they all have to face a threat that only their combined powers can defeat, like a cosmic entity that is draining the life force of both their universes.
One idea could be that the Eternals' powers are needed to defeat a new, extremely powerful villain that the Avengers alone can't handle. For example, a cosmic entity that can manipulate time and space. The Eternals' long - lived knowledge and unique abilities would be crucial in formulating a battle plan.
Well, perhaps in the fanfiction, there could be a cultural exchange of sorts. The Eternals could introduce the Avengers to their long - lived and different ways of life. This might lead to some interesting character development, like Thor learning new forms of combat from an Eternal warrior. Also, the discovery of a hidden connection between the two groups, such as a shared ancestry in some ancient, forgotten time, could be a great plot point.
