Definitely 'Thor: God of Thunder'. This story follows Thor at different points in his life - as a young and brash god, a more experienced warrior, and an even wiser and more powerful being. It shows his growth over time and his continuous struggle against evil, like the dark entity known as Gorr the God Butcher.
The 'Thor: Ragnarok' storyline is also great. It delves into the end of Asgard and Thor's journey to save his people. It has a lot of character development for Thor, as he loses his hammer but discovers his true strength within himself. There are also many memorable side characters and epic battles against the forces of Hela.
One of the best is 'Black Widow: Forever Red'. It focuses on Natasha Romanoff's backstory and her journey. It's a great exploration of her character. Then there's 'Hawkeye: My Life as a Weapon'. This novel gives us a closer look at Hawkeye, his skills and his life outside of the big team - ups.
I think 'Full Black' is one of his best. It has a really engaging plot that involves a lot of mystery and danger. The characters are well - crafted and the action scenes are exciting.
The 'Infinity Gauntlet' storyline is hard to beat. Thanos' quest to gather all the Infinity Stones and his snap that wipes out half of all life in the universe is a huge and epic story that has had a major impact on the Marvel universe both in comics and in the movies.
I think 'Uncanny X - Men' has some of the best graphic novels. 'The Dark Phoenix Saga' is a well - known and epic story within the X - Men universe. 'Iron Man: Extremis' is also a great one as it reimagines Iron Man in a modern and technological way. And 'Black Panther: A Nation Under Our Feet' which gives a deep look into Wakanda and Black Panther's leadership.
I would also recommend 'Captain Marvel: In Pursuit of Flight'. It has a fast - paced story that showcases Captain Marvel's powers and her determination. The graphic novel also has some great character interactions that add depth to the overall story.
There's a fanfiction called 'A Meeting of Titans: Thor and Captain Marvel'. In this one, they are brought together by a mysterious force. The story delves into their insecurities as well as their strengths. It's a long - form fanfiction that really explores their relationship in great detail, with over 50 chapters that keep you hooked from start to finish.
In my opinion, 'Full Black' could be considered one of the best. It showcases Thor's ability to create complex characters. The main character, Scot Harvath, is put in some really tough situations and his development throughout the story is quite engaging. It also has a very fast - paced narrative that keeps you hooked from start to finish.
The X - Men team of Wolverine, Storm and Cyclops can also work well. Wolverine is a great close - combat fighter with his adamantium claws. Storm can control the weather and deal damage over a large area. Cyclops has his powerful optic blasts. In the story, they can fight against different types of enemies. For example, Wolverine can take on physical threats, Storm can handle environmental challenges and Cyclops can deal with long - range threats.
Most of the time, the comics that form the backbone of the Marvel Universe and have significant impact on the characters and overall storyline are regarded as canon. However, there are always exceptions and special cases that can muddy the waters a bit.
