Well, I'd say 'The Killing Joke' is essential. It delves deep into the relationship between Batman and the Joker. Then there's 'Batman: Hush'. It has a great mystery element with many of Batman's rogues gallery involved. 'Batman: Long Halloween' is also a great read. It's a noir - style story that focuses on Batman trying to solve a series of murders during the holidays, with appearances from many well - known villains.

Another great one is 'Batman: Year One'. It tells the origin story in a really engaging way, showing how Bruce Wayne became Batman and his early days in Gotham. And 'Arkham Asylum: A Serious House on Serious Earth' is also a must. It has a very unique and dark take on Batman and the villains in Arkham.
I would also recommend 'Persepolis' by Marjane Satrapi. This graphic novel is a memoir that gives a personal and eye - opening look at life in Iran during and after the Islamic Revolution. The simple black - and - white art style effectively conveys the emotions and experiences of the author, and it's a great way to learn about a different culture and its history.

This graphic novel is part of a larger story arc that involves other Justice League members. It's exciting because it shows Aquaman's place in the DC universe and how important he is in big - scale battles.
Definitely check out 'Deadpool by Daniel Way'. This run really delved deep into Deadpool's character. It has his crazy adventures, his interactions with other Marvel characters like Cable, and his signature humor. The art style also complements the chaotic nature of Deadpool really well.

I highly recommend 'Locke & Key'. It has a great blend of horror and mystery elements. The story is set in a large, old house with keys that unlock different, often terrifying, powers and secrets. Also, 'Hellboy' has some great horror elements in it. It follows the adventures of a demon - like hero fighting against various supernatural threats in a dark and spooky world.
One must - have graphic novel is 'Maus' by Art Spiegelman. It's a powerful and unique take on the Holocaust, using animals to represent different groups. Another great one is 'Watchmen' by Alan Moore. It's a complex and thought - provoking work that deconstructs the superhero genre. 'Persepolis' by Marjane Satrapi is also a must. It tells a personal story set against the backdrop of the Iranian revolution.
