Many people, or groups believe that Zombies are in fact caused by a virus and are "fictional" for the most part; only sharing the spotlight in those crazy b class horror movies and a few of the more major franchises.

Often featured in both Haitian Vodou, and Folk Catholicism. In the eyes of most; he is considered charming, debauched and obscene in most senses and dresses in the traditional Haitian funeral attire.
A top hat, black tuxedo (dinner vest/jacket), dark glasses and cotton plugs in his nose. He shares a fondness for rum, and tobacco and is often called upon to heal those nearing death or that have died as he is the only one capable of taking them upon the embrace of death. It widely known or believed that only the Baron is capable of taking you into heaven, and to defy him or insult him in some manner (such as suicide) you are forced to walk the earth as an undead corpse with no freewill.
