Events of GTA V
Karl can only be selected in The Big Score. In the subtle aproach, being a gunman with little experience, he will drop some gold bars while loading the Gauntlet, causing $18 million in loss for the crew, if selected as the second gunman, there will be no consequences to the heist.
In the obvious aproach, Karl does a decent job being either the first or second gunman. Since its impossible to Karl have previously experience, if he is the second gunman, he will have more chances of dying during the shootout agaist the police. The player needs to protect him, so the heist doesn't have any casualities.
- During The Big Score, he speaks as if he is an Epsilonist and yells at officers that his money is going to a charity/religion, implying that he has devoted his life to their cause.
