There could be a group of characters. For example, a journalist who is investigating strange events that are linked to the 'shadow out of time'. A historian who has some knowledge about past events that might be related to the current situation. And a psychic or someone with special abilities who can sense the presence of the 'shadow out of time' and helps the others in their quest to understand and stop it.
Since I don't have access to the 'Shadow out of Time Graphic Novel', it's hard to say exactly. However, it's possible that the main characters include someone who has the ability to traverse different times, like a time - traveler of sorts.

The main character is a man whose mind gets intertwined with that of an alien being from another time. His experiences and his struggle to come to terms with what is happening to him form a major part of the story.

And there would be an enemy or a group of enemies that the hero has to face. The relationships between these characters would drive the plot forward.

Since it's a 'Wolf in Shadow Graphic Novel', the wolf is surely one of the main characters. There may also be other animals or perhaps even human - like characters who interact with the wolf.
