Well, Harry Potter for sure. He's the hero of the story, so when you're doing a crossover with a god, he's an obvious pick. People like to write about how he might use god - given powers to fight against Voldemort in new and exciting ways. Ron is also a character that shows up in these crossovers sometimes. He could be given some sort of special ability by a god, which might help him be more confident and useful in the group. And then there's Voldemort. Imagine him trying to either steal the power of a god or being in conflict with a god - like entity. It would make for a really intense story.
Harry Potter himself is very commonly paired with god - like entities. Since he is the main character, it makes sense that fanfiction writers would explore how his story changes when he has the influence or power of a god on his side. Hermione is also a popular choice. Her intelligence combined with god - like assistance could lead to all sorts of new magical discoveries. Another common character is Dumbledore. His already powerful and mysterious nature can be enhanced even more when paired with a god - like being, and it can add more depth to his backstory and actions.
