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.
A cool Bastion fanfiction could revolve around Bastion being reprogrammed in a unique way. Perhaps by a brilliant but slightly mad scientist character. This new programming gives Bastion new abilities and a whole new purpose, and the story could be about how he deals with this new identity within the Overwatch 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 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 interesting TF2 Overwatch fanfiction could be about a crossover battle where the characters from both universes accidentally meet in a strange dimension and have to fight together against a new, unknown threat. For example, the Engineer from TF2 and Torbjorn from Overwatch might team up to build some amazing defenses.
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.
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.
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.
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.
The main elements are its origin as a war machine, its getting damaged in battle, and its new connection with nature.
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.
