#4. The Undertaker sends Edge to Hell inside Hell in a Cell: SummerSlam 2008
Hell in a Cell is considered the devil's playground, so if you're wondering just how much of The Undertaker you'll see on this list, that should give you an answer.
A lot of people tend to think of Edge as one of John Cena's greatest rivals. However, The Rated-R Superstar also had a stellar feud with the legendary Deadman. Throughout 2008, Edge and The Undertaker carried the SmackDown brand.
It started with their fantastic WrestleMania XXIV main event match, where Edge nearly broke The Undertaker's undefeated streak. Though he failed, losing the World Heavyweight Championship to The Phenom, Edge would ultimately get his title back thanks to the help of La Familia, forcing The Undertaker to leave WWE as well.
The Undertaker returned that summer, leading to their feud culminating at SummerSlam 2008 in one of the more sadistic Hell in a Cell matches.
The Undertaker and Edge brutalized one another, but it was The Deadman who ended up with the victory. A chokeslam off the top rope through tables, a con-chair-to, and even a spear before putting away his rival with a Tombstone Piledriver.
That wasn't it for Edge, though. No, unfortunately Hell in a Cell was just the beginning. The Undertaker wasn't finished with him, and decided to take Edge up for one final chokeslam. Standing on top of a ladder, The Undertaker launched Edge down to the mat, driving him through it. Edge went from Hell in a Cell straight to Hell as flames erupted from the hole that he'd created.
Edge learned an important lesson that night. No matter how many times you get one over on The Deadman, in the end The Undertaker always gets his pound of flesh.
