One possible plot for this fanfiction could be that Bastion accidentally activates an ancient Omnic protocol. This protocol sends out a signal that attracts the attention of both Overwatch and a group of evil Omnics. The Overwatch heroes, including Bastion's friends like Torbjorn, come to Bastion's aid. Together, they have to fight off the evil Omnics and find a way to deactivate the protocol before it causes more chaos. It could be a story of friendship, sacrifice, and the struggle between good and evil in the Overwatch universe.
Definitely Torbjorn. Since he has a connection with Bastion in the original Overwatch lore, he would be a central character. Reinhardt could also be involved. His chivalrous nature might lead him to protect Bastion if he saw it was in trouble. And of course, Mercy. She's always there to heal and help, so if Bastion gets damaged during the story, she would be there to patch it up.
One common theme is Bastion's struggle to understand humanity. Since Bastion is a sentient omnic, many fanfictions explore how it tries to make sense of human emotions, behaviors, and relationships. Another theme is Bastion's friendship with other Overwatch characters, like Torbjörn who has a connection to Bastion's creation.
One great Overwatch Bastion crossover fanfiction is 'Bastion in Another World'. It has Bastion being transported to a fantasy realm. The author does an amazing job of describing how Bastion's mechanical nature interacts with the magic of the new world.
The Bastion origin story in Overwatch is about a war machine that was created for combat. Bastion was part of a large army of mechanical units. After a great war, Bastion was damaged and lay dormant in a forest. There, it began to interact with nature and developed a new understanding, rather than just being a tool for destruction.
One common theme is friendship. Bastion, being a rather unique character in the Overwatch universe, often forms unexpected friendships in fanfiction, especially with other heroes. Another theme is redemption. Bastion's past as a war machine can lead to stories where it tries to atone for its actions. And of course, there are also romantic themes in some of the fanfictions, exploring a relationship between Bastion and another character.
One good example could be those that explore Bastion's discovery of the world beyond combat. They might focus on his interactions with nature, like when he encounters a lemon tree. The author could describe how Bastion is intrigued by the lemons, their smell and texture, and how this simple encounter changes his view of the world a little bit. This kind of fanfiction can add depth to Bastion's character in a rather unique way.
A common theme is friendship. Given their different backgrounds - Bastion being a reformed war machine and Orisa being a protector - their friendship can be really interesting to explore. They learn from each other.
Another reason is that fans love to explore different scenarios for Bastion. In crossover fanfics, Bastion can be put in situations that are not possible in the original Overwatch game. For example, Bastion could be in a world full of magic and have to adapt. This creates a lot of interesting storylines.
One interesting Bastion Overwatch fanfiction could be about Bastion's journey to discover more about the world beyond the battlefield. Maybe it shows Bastion interacting with different characters in a peaceful setting, like exploring a new city with Tracer as a guide.
One possible plot could be that Naruto, in his Six Paths form, somehow gets transported to the Overwatch universe. He might initially be confused by the high - tech environment. He could then meet some of the Overwatch heroes, like Tracer. Maybe they start off as foes, with Naruto's power being seen as a threat. But as they learn more about each other, they team up to face a common enemy that is threatening both the world of Overwatch and Naruto's own world.
