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.
Well, redemption can also be a theme. Maybe the OC has a past they are not proud of and they are seeking redemption through their actions in the Overwatch universe. And there's often the theme of adaptation. The OC has to adapt to the high - tech and chaotic world of Overwatch, with all its different cultures and species. This can lead to some humorous and also poignant moments in the fanfiction as they learn to navigate this new world.
Growth is also prevalent. They start as students at Duel Academy and as the fanfiction progresses, they develop not only as duelists but also as individuals, learning important life lessons and becoming more confident in themselves.
