The protagonists of the last three things you read/watched/played are the members of your zombie apocalypse team. How screwed are you?
1. Miles Vorkosigan (Komarr)
Miles has a great deal of military experience and is a genius. If he could bring plasma arcs and needle grenades, I don't see any problem. Unarmed and alone, I still think he is a match for an army of zombies.
2. Phantom Reporter (The Twelve)
The Phantom Reporter is a mundane superhero from World War II who slept for 60 years and recently gained fire powers. Zombies burn pretty well. That's useful, and considering how disappointingly this series ended, it would be no loss if he got eaten by zombies.
3. Peter Kingdom (Kingdom)
A kind-hearted British solicitor played by Stephen Fry is probably not the best line of defense in a zombie apocalypse. Still, every zombie hunting team needs someone to keep morale up.
I can think of better teams, but this could have been much much worse.
