Warning: many, many Walking Dead spoilers follow...

The Walking Dead is about a lot of things. It's about leadership, and variances in leadership styles; it's about making tough choices and sacrifices; it's about the human will to survive, despite all evidence that full-scale annihilation is not only possible, but probable - and imminent. Lest we forget, though, it's also about zombies! Glorious, gory zombies.

In compiling this list we were looking for zombies that were either iconic, a creative and/or technical feat, or represented a significant moment for the characters and/or plot. Considering the special make-up effects on this series are second to none, we found plenty that were all of the above.The following is the result of our search. We're essentially assuming that you're caught up on the show if you're reading this list and have some context in terms of the characters and story. Reminder: there are spoilers!Having said all of that, we invite you to take a look at our top 25 Walking Dead walkers and let us know what you think!

25 The Lonely Zombie

24 Deputy Leon Basset

23 Who's Your Flyboy?

22 Romero Double Take

Thanks to the Zombie Research Society for the screen grabs.

21 Autopsy Zombie

This one almost feels like a homage to the movie Jaws (there is a real Jaws Easter egg coming up shortly). Do you remember when Hooper gutted the Tiger shark looking for body parts in Jaws? He was searching for evidence that the shark had indeed killed the missing people in Spielberg's classic. Well, the autopsy zombie is a nice parallel to that sequence. Rick and Daryl gutted the walker in order to see if it had had Sophia for a bite of lunch when the little girl went missing in Season 2. The scene is both gruesome and technically well executed and certainly worth a mention.
