Well, the uniqueness lies in the fact that it combines two very different yet equally captivating universes. 'The X - Files' has a very different aesthetic and narrative style compared to '30 Days of Night'. The former is more about mystery and the search for truth, often with a scientific bent. The latter is a more straightforward horror, all about survival against vampires. When these two are brought together in the graphic novel, it creates a new kind of story that can attract fans of both and also introduce new and exciting elements to the existing fan bases. It's a fresh take on both concepts, and the graphic novel format allows for some really cool visual interpretations of the combined worlds.
One thing that makes it unique is that it can take the investigative nature of 'The X - Files' and apply it to the horror - filled world of '30 Days of Night'. The X - Files agents are used to dealing with all kinds of out - there scenarios, but vampires are a whole new level. So seeing how they approach this new threat, and how the two storylines interact, is what makes it stand out.
The unique aspect is the blend of two distinct worlds. 'The X - Files' with its focus on government conspiracies and strange phenomena, and '30 Days of Night' which is centered around vampires. It's not often you see these two concepts combined in a graphic novel.
