1. Invincible
One of the best superhero comics of all time. Seriously, there is NO hyperbole going on here. If you haven't read Invincible, you kinda need to.
When trying to sell the book to new readers, most of us fans have adopted a similar pitch: "What if Spider-Man had Superman's powers?" Now, this pitch really, truly simplifies what is actually a wonderfully complex comic book.
Mark Grayson is a teenager working a terrible job and counting down the days. To what? Why, to his super powers finally kicking in. Because Mark is the son of Omni-Man, the world's greatest superhero. And when those powers do kick in (in the single best "discovering powers" scene in the history of comic books), he's off to the races in some lighthearted superhero action.
But it's not all fun and excitement, as there is in fact something deeply wrong in Mark's world. I really can't say too much more without ruining the story, but I promise you that if you pick up the first three collections (or just the first hardcover, which contains the same material), you will be hooked.
I promise, cross my heart, hope to die.
