I think that members of the internet are all too aware of the real dangers of the coming zombie apocalypse. It is time now to formulate a survival strategy and prepare ourselves for Armageddon.Forget what you have seen in movies like Zombieland or Dawn of the Dead. In reality these tactics will do nothing more than get you killed.
The first and most important step in the event of the zombie apocalypse is to find yourself a well rounded pokemon. The things that should be considered is the strength, resilience, mobility, and utility of your new companion. Keep in mind this pokemon could be your only friend for the rest of eternity so choose wisely. I personally would go for Onyx, he is fairly large, offers great mobility and possible shelter, and most importantly cannot be infected by the zombie horde.
Step two should only be attempted after you have solidified shelter and a food source. You may now begin to attempt to contact other survivors. Do not put too much priority in this at first, survival is still priority one. Start with a small group, larger numbers will require more food and pokemon battles. Try to find other survivors who will offer the most utility to the group.
Once you have a band of followers you may begin to reconstruct a civilization. Using larger pokemon as the labor force security, holding off the zombie horde should not be very difficult. Now is not the time to get sentimental with the daylight, if you have a taskforce capable of building underground make sure to utilize it. Again, Onyx would serve as a major help here.
Undoubtedly, your civilization will have its share of crazies and they should be immediately exiled or killed, now is not the time to compromise security. Once all of this is done, all that is left to do is keep guard and ride out the infestation.
