Some fanfiction writers get creative by creating new hero - like characters within the Overwatch universe. These new characters could have unique abilities and backstories that tie into the existing lore. For example, a character who has the ability to control weather and was born in a small, isolated village that was affected by the Omnic Crisis. This new character could then interact with the established heroes and add new dynamics to the stories.
One idea could be an Overwatch crossover with the Star Wars universe. Imagine Tracer using her time - jumping ability in the middle of a lightsaber duel on Tatooine. Another could be a crossover with the Harry Potter world, where Winston, being the intelligent gorilla, might be intrigued by the magic at Hogwarts and try to study it. And a crossover with the Lord of the Rings, with Reinhardt as a valiant knight facing off against Orcs in Middle - earth.
One idea could be an Overwatch crossover with the Star Wars universe. Imagine Tracer using her time - traveling abilities in the middle of a lightsaber duel. Another could be a crossover with the Harry Potter world, like Pharah flying on her rocket launcher over Hogwarts. And a crossover with the Marvel universe, where Reinhardt teams up with Thor to fight some powerful villains.
A crossover with a cyberpunk - themed story could be really cool. Genji's cybernetic enhancements would fit right in. He could be on a mission in a dystopian city, facing off against powerful corporations and their enforcers. Along the way, he might meet new allies who are also fighting for justice in this harsh environment.
Another concept could be a story where a character from Halo, say Master Chief, gets transported to the Overwatch universe. He has to adapt to the different rules and powers there while trying to find a way back home. Along the way, he could form unexpected alliances with Overwatch heroes and learn about their world, and they could learn from his military discipline and combat experience.
One idea could be a story where Tracer accidentally travels back to the Omnic Crisis era. She could meet the younger versions of the original Overwatch founders and try to help them in ways that might change the future of Overwatch. Another could be Reinhardt going back in time to his early days as a Crusader and having to relive some of his toughest battles with the knowledge he has now.
Another interesting concept could be a crossover in which the technology from TF2 is integrated into the Overwatch universe, or vice versa. For example, the Medic's healing technology being used to enhance the Overwatch medics' abilities. This could lead to some really cool character interactions and story developments as they learn to work with new equipment and each other.
A great concept could be a crossover tournament. The two teams, TF2 and Overwatch, compete in a series of challenges. These challenges could include things like a sniper - only round where Widowmaker from Overwatch and Sniper from TF2 go head - to - head. Or a melee combat round with Reinhardt and the Demoman. It would be a chance to explore the different abilities and personalities of the characters in a competitive setting.
One plot idea could be that the Overwatch heroes are transported to the Naruto universe. They have to adapt to the chakra - based powers and the different combat styles. Meanwhile, they might also introduce some of their own technology and teamwork concepts to the Naruto characters, leading to some interesting interactions and battles.
Maybe the villains from BNHA team up with some of the evil forces in the Overwatch world. Then the combined good guys, including both BNHA heroes and Overwatch agents, have to figure out how to defeat this new, dangerous alliance. It could lead to some really cool battles and character interactions, like All Might facing off against Doomfist.
You could also write a fanfiction about Naruto being raised by a different clan in the village. For example, if he was raised by the Uchiha clan, it would have a huge impact on his character development and relationships within the village.
