Definitely. Hulk and Thanos have squared off in the comics. These clashes usually involve intense action and showcase the unique abilities and personalities of both characters.
For me, 'The Incredible Hulk' #340 is essential. It has a significant plot development and showcases some amazing art. Also, 'Planet Hulk' is a great pick as it presents a unique storyline and character development for the Hulk.
Sure, She-Hulk is related to Hulk. Jennifer Walters, aka She-Hulk, got her powers because of a blood transfusion from her cousin Bruce Banner, who is Hulk. This connection is a key part of their storylines in the comics.
