The 'culture clash' trope is really popular. Since Percy comes from a world of Greek gods and Hellboy from a world of demons and the paranormal, there are a lot of differences in their beliefs, values, and ways of doing things. Writers often explore how they overcome these differences to work together. Also, the 'power - up' trope can be seen, where Percy or Hellboy gain new abilities or enhance their existing ones during the course of the fanfiction.
One common trope is the 'fish out of water' situation. For example, Percy suddenly finding himself in Hellboy's world and having to adapt to the much darker and grittier environment. Another trope is the 'team - up against a greater evil'. This usually involves Percy and Hellboy combining their unique skills to take on a powerful villain that threatens both their worlds.
A popular trope is the 'mystery element'. There's often a mystery that needs to be solved, like a strange artifact that has connections to both the Percy Jackson universe and Hellboy's world. The characters have to figure out its origin and purpose. And of course, the 'unlikely friendship' trope. Despite their different backgrounds, Percy and Hellboy form a strong bond in many fanfictions, which is really heartwarming to read.
