One exciting plot possibility could be Asura facing off against Darkseid. Their immense power levels would make for an epic battle. Asura's rage and his unique combat style against Darkseid's Omega Beams and his tyrannical rule would be a sight to behold. Another could be Asura teaming up with Superman. They both have a strong sense of justice. Asura could learn about a different kind of heroism from Superman, and together they could take on a common enemy like Doomsday. It would be interesting to see how their powers combine and what kind of dynamic they would have.
Another unexpected pairing would be Asura and the Flash. The Flash is so fast and relies on his speed and quick thinking, while Asura is more about raw power. The Flash could try to outmaneuver Asura, but Asura's power might be too much. However, if they could find a way to work together, they could be a very effective team. For example, the Flash could lead enemies into Asura's path for him to smash.
A third possibility is a crossover based on a multiverse - breaking event. Maybe a powerful magic user accidentally creates a rift between the Arrowverse and the Marvel universe. This leads to a chaotic situation where heroes and villains are randomly shuffled between the two universes. The heroes then have to figure out how to put things right while also dealing with the new threats they encounter in the foreign universes.
One possible plot could be that Asura finds himself in the Street Fighter universe due to some mysterious rift. He then gets involved in the various battles and rivalries. Maybe he initially clashes with Ryu, thinking he is a threat, but later they realize they have a common enemy that is causing chaos in both their worlds.
Perhaps in the crossover fanfiction, the dark energy in the Mass Effect universe has some strange effect on Asura. It either amplifies his wrath to uncontrollable levels or gives him new powers. Meanwhile, the Asari, with their biotic abilities, try to form a connection with Asura to understand his nature. This connection could lead to a mutual understanding between Asura and the Mass Effect races, and together they work towards a common goal, like saving a planet that is on the verge of destruction due to a combination of Mass Effect threats and something related to Asura's past.
One popular theme is the crossover with other action - based video games. For example, a crossover with God of War could be interesting as both have powerful and somewhat angry protagonists. The clash of their worlds and fighting styles would make for an exciting story.
The plot could involve a tournament in the Street Fighter world where Asura is an unexpected entrant. His over - the - top powers would shock the other fighters. Maybe some of the Street Fighter characters would be intrigued by his raw power and try to learn from him, while others would be jealous. This could lead to various matchups and character development for both Asura and the Street Fighter cast.
One exciting plot possibility could be a telepathic encounter. Maybe Jean Grey from X - Men senses the unique psychic energy in Smallville. She could be drawn there to investigate. This could lead to an encounter with Chloe Sullivan, who has her own mental abilities in the Smallville universe. Their meeting might result in a power struggle or an exchange of knowledge about their different worlds.
Another option is to check out Reddit. There are subreddits related to Asura's Wrath where fans might share or discuss crossover fanfictions. You can also post a request asking if anyone knows where to find good Asura's Wrath crossover fanfictions. However, make sure to follow the subreddit rules while doing so.
A really interesting crossover idea could be a tournament - style story. Characters from both Asura Wrath and Naruto universes are gathered to compete in a tournament. This would allow for all kinds of match - ups. For example, Rock Lee's taijutsu skills against an Asura Wrath character who is also a melee combat expert. It would be exciting to see who would win and how they would adapt their fighting styles.
Asura and Shepard would be really interesting. Shepard is used to leading and making tough decisions, while Asura is driven by his wrath. Their different personalities would create a lot of tension and also great moments of cooperation. For example, when facing a tough battle, Shepard might try to come up with a strategic plan, but Asura could just charge in with his brute force. They would have to learn to work together.
