Dave is a Survivor who was available as part of the original Kickstarter for anyone who pledges at Abomination level ($100) or above.
Dave - The Geek
"Yeah sure, take the shotgun if you want, I'll take the... AMMONIUM... NITRATE!"
As far as he remembers, Dave always found reality to be terribly boring. So he locked himself up in an imaginary world and learned piles of useless stuff... useless until now. Dave is a fount of knowledge. His chemistry mastery makes him look like a superhero amongst other survivors. At least until he opens his mouth, then everyone remembers he's a real geek.
Dave came with a Zombivor figure (shipped seperately) as the Kickstarter reached its Stretch Goal of $100,000.
Dave's appearance is based on the character of Sheldon Cooper, played by Jim Parsons, in the TV series The Big Bang Theory.
