The third season of Z Nation commences this Friday at 8/7c. Do you know your Z Nation alphabet?

Here's the world of the zombie apocalpyse, from A to Z.

1. A is for Addy
   
   
   Anastasia Baranova (Addy) provides the Z-whackin' tunes.

   
   
   Ex-Sister of Mercy and Z-whacker-wielding zombie killer.
    
2. B is for Bernadette
   
   
   Bernadette (Missi Pyle), the kooky leader of a group of 'extranauts' who believe they'll soon be rescued from the apocalypse by a race of aliens … and that Murphy is their emissary ...

   
   
   She lives in Roswell (or RoZwell, depending on how cute you want to get) and believes in aliens. The truth is out there.
    
3. C is for Citizen Z
   
   
   When we last see Citizen Z, he and his trusty canine have abandoned the Northern Light listening station and are now traversing the snowy wasteland, where a MYSTERY FIGURE approaches them! Who could it be ...?

   
   
   PFC Simon Cruller is the lone survivor of the Northern Lights listening post. He's something of a guardian angel to the survivors, when he's not being attacked by Z's himself. When last we saw him, he and his dog were wandering the icy hinterlands, probably freezing to death.
    
4. D is for Doc
   
   
   
   
   He's not really a doctor. But in the zombie apocalypse, you take what you can get. And you know what? You'd be glad to get Doc.
    
5. E is for Escorpion
   
   
   The man responsible for those deaths? Hector Alvarez, aka Escorpion, the head enforcer of a criminal empire known as the Zeros. The gang has to contend with them … and with the scores of bounty hunters who are after 'The Murphy.'

   
   
   Not to be trifled with. Though he seems to be one of the good guys now. Who knows.
    
6. F is for Forman
   
   
   
   
   Remember this guy? The owner of the 'Forman-mobile,' a tricked-out anti-zombie mega-transport that's unfortunately never seen. Forman's no longer with us.
    
7. G is for Gideon Gould
   
   
   … and Dr. Gideon Gould (Anthony Michael Hall), a world-renowned expert in conflict resolution who's spending the apocalypse with a group of survivors at a never-ending corporate retreat.

   
   
   He's a world-renowned expert in corporate conflict resolution. Although we don't recommend opening a dialogue with him.
    
8. H is for Helen
   
   
   
   
   The leader of the Sisters of Mercy, a heavily armed commune that doesn't allow men folk. The Sisters all eventually burned to death or got eaten by the zombie bear they kept in the barn. (Yep.)
    
9. I is for Immune
   
   
   
   
   That's what Murphy is to the zombie virus. It has its pros and cons.
    
10. J is for Jacob
    
    
    
    
    This dum-dum once led the Resurrection Cult, a bunch of crazies that considered the zombie apocalypse to be the second coming of God. He's no longer with us.
     
11. K is for 10K
    
    
    
    He calls himself that because that's how many zombies he plans on killing. We're rooting for him to reach his goal.
     
12. L is for Lucy
    
    
    And finally, Murphy's daughter Lucy seems to be doing just fine ... at a tea party with her decomposing foster parents.

    On to Season 3!

    
    
    That's Murphy's zombaby. Well, zomtoddler, last we saw her. She's alive (-ish) and well.
     
13. M is for Murphy
    
    
    
    
    This is the face of the savior of humankind.
     
14. N is for Northern Lights
    
    
    
    
    That's the NSA listening station where Citizen Z was posted. It's located in the Arctic. How'd he get such a sweet gig?
     
15. O is for Operation Bitemark
    
    
    
    
    That's what Citizen Z calls the group of survivors escorting Murphy to California. They change vehicles as often as most pre-apocalypse people changed their underwear. 
     
16. P is for Pisay Pao
    
    
    
    
    That's the name of the actress who played Cassandra, who was mercied by 10K after being in an increasingly volatile half-human/half-zombie state. We miss Cassandra.
     
17. Q is for Quarantine
    
    
    
    
    That's what this poor bastard who was exposed to the Z virus is in. It doesn't end well.
     
18. R is for Roberta
    
    
    
    
    She's the boss lady of Operation Bitemark ... and an artist with a machete.
     
19. S is for Sketchy
    
    
    
    
    A former colleague of Doc's, Sketchy McClane was the overlord of Fu-Bar, an outpost where one can drink, drink some more, and participate in a zombie-shooting contest. We love this guy.
     
20. T is for Thompson
    
    
    
    That was Mack's last name. Betcha didn't know that, eh? Anyway, he's dead now.
     
21. U is for Undead
    
    
    
    
    That's what the Z's are. It's a problem.
     
22. V is for Vasquez
    
    
    
    
    One of the shining stars of Season 2. We hope to see him again.
     
23. W is for Wilbur
    
    
    
    
    Before he died, Wilbur Grady valiantly attempted to shut down an unstable nuclear reactor at a South Dakota power plant. His former colleague, Homer Stubbins, saw it through.
     
24. X is for X-rated
    
    
    
    
    Murphy opened a zombie stripper club in Cheyenne, Wyoming. Of course he did. And it's probably still there.
     
25. Y is for Yuri
    
    
    
    
    That's Citizen Z's imaginary friend, a Russian cosmonaut conjured by oxygen deprivation. He likes drinking and playing video games. He's also imaginary. Did we mention that?
     
26. Z is for Zunami
    
    
    
    
    This is something that happens.
