In an 'Avengers vs Ross' fanfic, a possible plotline could be that Ross has discovered a way to replicate the Avengers' powers for his own military use. The Avengers object to this unethical practice and a battle ensues. Another idea is that Ross is framed by a shadowy organization and the Avengers initially believe he is the bad guy and start fighting him. As the story progresses, they realize their mistake and team up to take on the real enemy. And of course, there could be a plotline where Ross simply wants to assert his authority over the Avengers and they won't stand for it.
A plotline might involve Ross creating a super - weapon to counter the Avengers' powers. The Avengers then have to figure out how to neutralize this weapon and deal with Ross at the same time. Maybe there's a political angle where Ross is trying to pass laws to restrict the Avengers' activities and they oppose him, which escalates into a physical conflict. There could also be a situation where Ross teams up with some of the Avengers' villains to take them on.
Well, it really depends on how the fanfic is written. If the Avengers are united and at their full strength, they would likely overpower Ross. They have superhuman abilities, advanced technology, and great teamwork. However, if Ross has some sort of powerful weapon or strategic advantage in the fanfic, he could potentially put up a good fight.
Perhaps there's a plotline where they are on opposite sides of an issue within the village. This causes them to oppose each other physically. It could be something related to a new law or a decision made by the Hokage. As they fight, they also have to deal with the moral implications of their actions. Sakura might be fighting for what she believes is right for the well - being of the villagers, while Neji has his own reasons rooted in his clan's values or his personal code of honor. Their battle would not only be about physical strength but also about the clash of their ideals.
One possible plotline could be that Broly, in his rage, accidentally provokes Beerus. Broly, not knowing who Beerus is, attacks him. Beerus, initially amused, decides to teach Broly a lesson but soon realizes that Broly's power is growing at an alarming rate. This leads to an intense battle where Broly pushes Beerus to use his full power. Another plotline could be that Beerus hears about Broly's power and decides to test him. He travels to Broly's location and challenges him. Broly, seeing Beerus as a threat to his friends or his planet, fights back with all his might.
One possible plotline could be that Cell, seeking to prove his superiority, challenges Broly. Broly, in his usual berserk state, accepts without hesitation. The fight could start with Cell trying out his various attacks like the Kamehameha - like Solar Flare and his physical strikes. But Broly's power is just too much and he starts to overpower Cell. However, Cell then reveals a new, hidden ability that he has been developing in secret and the tables are turned for a while.
A plotline could involve Broly being sent to Kale's universe by some sort of interdimensional rift. Kale initially sees him as a threat and attacks. But as the fight progresses, they start to understand each other's power and motives. Or perhaps a fanfic could have a story where both Broly and Kale are training on the same planet. Their training methods clash, leading to a fight where they both learn from each other and grow stronger in the process.
A plotline could start with Frieza hearing about Broly's power and being jealous. He then devises a plan to ambush Broly. But Broly, being extremely perceptive in his own way, senses Frieza's approach and is ready for the fight. As the fight progresses, Frieza realizes that Broly is much stronger than he expected and has to use all his dirty tricks to try and win. Or perhaps the plotline could involve Broly being captured by Frieza's forces, and then Broly breaks free and goes on a rampage against Frieza and his minions.
A plotline could involve a special Pokemon that both Ash and Paul are interested in. They might compete to catch it, which could involve a series of challenges and battles. Or, perhaps there's a new type of Pokemon training technique that one discovers and the other tries to learn from or outdo. This could create an interesting dynamic in the fanfic.
Another plotline might be that the forces of evil launch a sudden attack on Comet's homeland. Comet has to fight back and in the process, uncovers a conspiracy within the forces of evil that could be used to their advantage. He then uses this knowledge to turn the tables on them.
Well, in a fanfic like that, the Avengers could constantly thwart Ross's plans. For example, if he tries to enforce some strict superhero registration laws, they could use their powers to outwit him at every turn. They might play pranks on him too, like using Hulk to accidentally 'bump' into his car or something.
Another plot could focus on Thor. After losing so much in Infinity War, he might become a bit of a recluse. But then he realizes that he has a responsibility to the remaining Asgardians and the universe. So he starts to gather the remaining heroes and form a new plan to fight against the consequences of Thanos' snap.
