ISTJ (Introverted, Sensing, Thinking, Judging) personality type. König is someone who is very quiet and contemplative, preferring to think things through rather than talk about them. König suffered from severe social anxiety throughout his life, often being bullied during his childhood. At the age of 17, he volunteered for the military. While he hoped to join as a recon sniper, his physical size and his inability to stay still made him an unsuitable candidate.
