In
Miss Peregrine's Home for Peculiar Children, by Ransom Riggs, there are clearly defined heroes and villains.
The main hero, Jacob Portman, is somewhat of an Epic hero. He doesn't have superpowers, and he has to overcome his fear of the villains (the wights and the hollowgasts) to save his friends. He accidentally journeys into Miss Peregrine's time "loop" where the peculiar children live. Once he finds out that they're all in danger, he returns home feeling more courageous. He also returns home a little more sane than before because he realizes that he's not crazy and that all the things his grandfather told him are true.
The other characters in the book, the peculiar children, are also heroes. They are more Romantic heroes because they use their "peculiar" powers to fight evil. Because their powers are somewhat unusual, they have to use their own ingenuity to figure out how their powers will help them. For example, one girl named Olive can levitate. She isn't entirely sure how her power will help her fight evil, but she thinks of a creative idea. When the kids are on a boat surrounded by fog, they tie Olive to the boat, then have her levitate above the fog so that they can see what's going on around them and where land is.
The wights and the hollowgasts are the villains in this book. Hollowgasts are things that were once peculiar children that experimented to try to conquer time and make themselves immortal. However, their experiment backfired and made their lives into a living death. Now, hollowgasts try to eat peculiar children because if they do, they will transform into wights. A wight is almost like a regular person, except for the fact that they don't have pupils. Wights try to hunt down peculiar children for the hollowgasts to eat. Wights are kind of like the hollowgasts' evil minions.
Hollowgasts follow the pattern of villains very closely:
Stage 1: Injustice
The hollowgasts tried to make themselves immortal but instead, they were turned into terrible beasts.
Stage 2 & 3: Obsession and Pride
The hollowgasts are obsessed with becoming regular people again.
Stage 4: Isolation
Because they are evil, people isolate the hollowgasts.
Stage 5: Detachment
Since the hollowgasts are so obsessed with becoming normal again and because they're isolated, they begin to have no sense of worth for human life.
Stage 6: Wickedness
Detachment is what allows the hollowgasts to kill and eat people.
