Well, 'Watchmen' is a classic 'Warrior Graphic Novel'. It's known for its complex characters and deconstruction of the superhero genre. 'The Sandman' is also a popular choice. It has a rich and imaginative world full of different mythologies and stories. There's also 'Fables', which takes fairy - tale characters and puts them in a modern - day setting with a lot of twists and turns.
Sure. 'Bone' is a great one. It has a wonderful mix of adventure, humor and amazing art. Another is 'Maus', which is a very powerful and moving story that uses animals to represent different groups in a historical context. And 'Persepolis' is also highly recommended, as it tells a personal and political story in a very engaging way.
