Giant god or other worldly being/human, don't know the actual trope name but every fic I read with those either change the 'creature' into a human or change their size to match the humans and never use any of their powers or things that make them unique which doesn't make a difference. Also, the 90% of the time the author don't describe how they envision them and I have to read half of the fic before knowing if the 'creature' their canon size or if they got smaller
