Flex Mentallo (1996-) #1
One of the best superhero comics ever published by one of the best writer/artist teams in comics history. If you’re on the fence about reading this, go ahead and jump in. It’s dense material, but a very rewarding experience. I would say the only prerequisite a reader needs is fluency in the language of the comics format, at which Morrison and Quitely excel.
Suggested for mature readers.
