Odin is, of course, a main character. In addition, characters from the DxD series like Issei Hyoudou often play important roles. They interact with Odin in various ways, sometimes as allies and other times as opponents, depending on the plot of the fanfiction.
One great 'I am Odin DxD fanfiction' story is 'Odin's Ascent in DxD World'. It has an interesting plot where Odin takes on a new role in the DxD universe and interacts with the existing characters in a unique way. Another one could be 'Odin's Reign in DxD', which focuses on how Odin's power and wisdom change the power dynamics in the DxD realm.
A common theme is the clash of different power systems. Since Odin comes from Norse mythology and DxD has its own complex power structure, seeing how they interact is often explored. Another theme is the idea of prophecy. How Odin's knowledge of the future might play a role in the DxD world's events.
Another possibility is Heimdall. As the all - seeing guardian of the Bifrost, he would be aware of Odin's situation from the start. He could be the one trying to piece together what happened to Odin and prevent any disasters that might occur as a result of Odin's wipe. His unique abilities and loyalty to Asgard would make him a strong candidate for the main character.
Typically, you'll see the main characters from the original High School DxD series like Issei Hyoudou.

There are also some fanfictions that focus on characters who are descendants of Odin in the DxD world, which add a whole new layer of complexity to the story.
