One interesting plot could be that the Young Justice team gets accidentally transported to the Avengers' universe. They initially face misunderstandings as the Avengers are suspicious of these new, young heroes. But then they realize they have a common enemy. For example, a powerful villain is trying to take over both universes. So, they must combine their skills and resources to stop the villain. The Young Justice members' unique powers and the Avengers' experience would make for a great dynamic.
Perhaps a villain from the Young Justice universe has somehow made its way to the Avengers' world and is causing havoc. The Young Justice team follows, and they team up with the Avengers. The Young Justice members, being younger and perhaps more impulsive, might clash with the more methodical Avengers at first. But as they get to know each other's strengths and weaknesses, they form a formidable alliance to defeat the villain.
One possible plot could be that a common enemy, like a powerful interdimensional villain, forces the Young Justice team and the Avengers to team up. They start off distrustful of each other, with the Avengers seeing the Young Justice members as inexperienced kids and the Young Justice team thinking the Avengers are too rigid. But as they face the villain's various attacks, they gradually learn to work together. For example, Superboy could team up with the Hulk in brute - force battles, while Robin and Iron Man use their intelligence to figure out the villain's weaknesses.
One idea could be that the Avengers end up in the Young Justice universe due to a malfunctioning portal. They team up with the Young Justice team to fight a common enemy, like a powerful alien threat that neither group could handle alone. The characters' different skills and personalities would create great interactions.
Definitely Superboy and Captain America. Superboy with his super strength and sometimes - confused sense of self could learn a lot from Captain America's strong moral compass and leadership. Another interesting pairing would be Robin and Black Widow. Robin's detective skills combined with Black Widow's espionage expertise could make for some really cool stealth and information - gathering missions.
One exciting plot could be that Thanos teams up with Darkseid. The Avengers and Justice League initially misunderstand each other's motives while trying to stop this powerful alliance. They end up in battles among themselves until they realize they need to work together. Iron Man and Batman could be the first to figure it out, using their intellects to analyze the situation.
The more experienced Avengers like Captain America would likely take on a mentoring role with the younger members of Young Justice. For example, he could give advice to Robin on leadership. Meanwhile, the more powerful Avengers like Thor might be a bit intimidating to the Young Justice team at first. But characters like Superboy could be eager to prove himself against Thor in a friendly sparring match.
The Avengers are used to a certain level of professionalism and order. The Young Justice team, on the other hand, has a more youthful and sometimes impulsive energy. This could lead to some friction at first. For example, Thor might find the Young Justice members' jokes and banter during a serious mission a bit off - putting. But as they face challenges together, they would start to understand and respect each other's ways. Hulk could even form an unexpected bond with a Young Justice character who isn't afraid of his power.
Well, a cool plot could be that some sort of cosmic event has merged their universes in a strange way. Members of the Avengers start showing up in the Justice League's world and vice versa. Iron Man could team up with Batman to figure out how to reverse the situation while Thor and Superman have an epic showdown that ends in mutual respect. And then they all work together to fix the messed - up universes.
One idea could be that a powerful cosmic threat emerges that neither the Justice League nor the Avengers can handle alone. So they have to combine their forces. For example, Superman and Thor could team up to take on a super - strong enemy, using their strength and lightning powers respectively. Batman and Iron Man might start off butting heads as they both think they have the best strategies, but eventually work together to outwit the villain's high - tech defenses.
Well, in a Young Justice vs Avengers fanfiction battle, if we look at pure power levels, the Avengers seem to have the upper hand on paper. But in reality, Young Justice has a lot of heart and determination. Their younger age might also make them more unpredictable. For example, Robin's intelligence and strategic thinking could find weaknesses in the Avengers' defenses. So, it's not as straightforward as just comparing powers. It would be a complex and thrilling encounter.
One idea could be that the Young Justice team gets accidentally transported to an alternate dimension where the Justice League has turned evil. The Young Justice members then have to figure out how to reverse the situation while also evading capture from their once - heroes. Another could be a time - travel plot where the Young Justice team travels back in time and teams up with the early days of the Justice League to stop a threat that was thought to be long gone but has resurfaced in their own time. A third idea is that a powerful new villain emerges who can only be defeated by a combined effort of the Young Justice and Justice League, but first they have to overcome their differences in fighting styles and leadership.
