Avengers Infinity War is largely based on the Infinity Gauntlet comic. Many key elements and plot points are drawn from it, but there are also some creative adaptations and additions to make it work for the cinematic universe.
The plot involves various characters boarding the Infinity Train. They have to face their inner demons, solve puzzles, and deal with the odd inhabitants of the train cars. The graphic novel explores themes like self - discovery and personal growth as the characters journey through the train's seemingly infinite expanse.
Infinity War comic is definitely worth a read. It has a rich storyline, stunning visuals, and introduces some interesting concepts that expand the Marvel universe.
Wolverine doesn't make an appearance in the Infinity War comic. The comic primarily centers around other characters and their battles against cosmic threats.
