A good Seeker in fanfic is often very fast and agile, like Harry was in the books. They need to be able to quickly spot the Golden Snitch in the chaos of a Quidditch match.
A really interesting fanfic is 'The Hidden Seeker'. In this story, the Seeker has some unique abilities that are not typical for a normal Seeker. The story weaves in elements of magic that are not often explored in the original books, and the Seeker's relationships with other characters, especially the team members, are very well - written. It's a must - read for any Harry Potter fan who loves the idea of a special Seeker.
A young and enthusiastic Pokemon researcher could be a great sidekick. They could provide Olivia with useful information about different Pokemon species and their habitats.
A really interesting 'Harry Potter seeker' fanfiction is 'The Seeker's Legacy'. It's about a seeker who is trying to live up to the great legacy of the previous seekers at Hogwarts.

One possible plot could be that Spiderman and Red Sonja are brought together through some sort of interdimensional rift. They initially clash due to their different fighting styles and moral compasses. Spiderman is used to protecting the city and trying not to kill, while Red Sonja is more of a fierce warrior from a different era. However, as they face a common enemy, perhaps an ancient evil that threatens both their worlds, they learn to work together. Their combined skills, Spiderman's agility and web - slinging along with Red Sonja's swordsmanship and combat experience, make them a formidable team. In the end, they not only defeat the enemy but also gain a new respect for each other's ways.
Since I don't know the details of 'Sonja Secret Story', I can't say much about Sonja specifically. But she could be a character with unique qualities, like being brave or having a special talent in the story.
