The Best Venom vs. Carnage Comics

With the Venom movie featuring Tom Hardy as Eddie Brock now in theaters, we're looking to the comics for what to expect for a possible sequel featuring the Spider-Man antihero.
Warning: beware spoilers for Venom!
The Venom mid-credits scene introduces Woody Harrelson's Cletus Kasady and directly sets the stage for the rise of Carnage in Venom 2. While we wait for the sequel to take shape, now would be a good time to go back and read some of the classic Venom vs. Carnage stories from the comics.
