Mountain Man

Gus, or Gustefer, as he is affectionally known by as his friends, was a painter turned Canadian samurai bat wielding warrior in the zombie outbreak.  He is the main character in the novel series Mountain Man by Keith C Blackmore. Gus is a dynamic character who changes throughout the series  of novels. He starts out as someone with very little confidence in himself who thinks he is only good at watching movies and painting. The outbreak makes him adapt and put the skills he learned in movies to the test. He goes through bouts of depression, alcoholism, and eventually insanity.  Various other charters promote change in Gus that ranges from positive influence to making him literally burn down the city.  In the end Gus turns out to be a reliable friend and someone willing to go great lengths to do the right thing, even if it means harming himself.
