E.g. I believe that Dracula as a Gothic monster is supposed to reflect the xenophobia and fear of the Other (though I am not too familiar with the text), while Hyde - though not a "monster" in the same way that Dracula is a vampire - is monstrous in his 'pure evil' and scientific origins, and is supposed to reflect the dangers of repression and an evil that is not countered by good (in order to advance Stevenson's argument about the necessity of a knowledge of both good and evil to make moral judgement). Stevenson's more human monster reflects his focus on the nature of humankind.
As I mentioned, I'm not too familiar with Dracula. However, you could discuss the appeal of the Other e.g. while the Other is kept at a distance by society, there is an inherent appeal in savage and more primitive cultures and beings. For example, with Hyde, despite his crimes and immorality, Jekyll still finds a pleasure in becoming his alter-ego. This is about the disjuncture between appearance and reality, between images of civilisation, composure, and rationality and the more complicated reality of desire, temptation, and sin.
