Extroverted Intuition (Ne): As ISIS’s resident inventor, Krieger is full of ideas and is excited by new prospects and experiments. Sterling and Malory rely on him because he’s so eager to carry out even the most unsavory of new ventures. Even bizarre jobs such as hiding a dead body or lobotomizing Malory’s fiance, Krieger jumps into with glee. He has created multiple clones of himself to varying degrees of success, has made multiple human/animal hybrids, and is responsible for the bulk of ISIS’s unique weapons and arsenals. Despite how smart he is, Krieger mostly invents for the sake of it, and isn’t even a legal doctor–the word only lies in his title because ‘Doctor’ is actually his first name.
Introverted Thinking (Ti): Krieger is a brilliant scientist, with multiple marvels of both medical and mechanical fields under his belt. He created a holographic, virtual wife for himself that’s so authentic, the state is allowing them to marry. He loves to conduct experiments, studying the effects his creations have on his peers and noting the outcomes. As absurdly smart as he is, there’s little denying that Krieger lives in somewhat a fantasy land–exclaiming ‘Smoke bomb!’ And running away to escape uncomfortable situations, for instance. He managed to build an immense sea vessel, only to end up destroying it due to his own lack of proper planning.
Extroverted Feeling (Fe): Krieger is generally very affable and pleasant. He’s always willing to lend a helping hand, offering his lab whenever Sterling or Malory are in a time of need. He seems to form genuinely emotional attachment to his own creations, particularly sad when he has to kill his animal hybrids, ‘Pigly’ and ‘Goatly’. The one person most capable of making him angry seems to be his own holographic wife, who he quarrels and fights with as one would with a real significant other.
Introverted Sensing (Si): Krieger’s past is a mysterious one. He claims to hail from Portugal despite his seeming German descent, and is very defensive of his heritage. He remembers the death of his father rather vividly, and seems to harbor resentment for the critical ‘mother’ of his virtual wife.
