Artemis Fowl: Butler [ISTJ]

All the pictures I can find are terrifyingly ugly fan art, Sorry.

Introverted Sensing (Si): As a bodyguard, Butler is responsible for mapping out environments for potential threats. He does so systematically, noticing the most subtle changes that could be a danger to Artemis. He has instincts that approach pure intuition, except they are always based directly on his years of experience. Not Ni but Si. He has a great trust in his experiences and is constantly advising Artemis on the typical way a situation is approached. His knowledge of the typical paves the way for Artemis to enact an atypical plan. His almost unwavering trust of Artemis is based on years of experience. He knows what Artemis is capable of because he has experienced it firsthand.

Extroverted Thinking (Te): Butler assesses objects in his environment based on their utility. ("Could we survive the fall if we used the mattress?") He calculates the potential of people and objects based on whether or not they help him achieve his objective: Protecting Artemis. While he trusts Artemis, Butler often questions the practicality of his plans. He executes his part of whatever plan Artemis has cooked up with maximum efficiency, bringing down enemies with no unnecessarily flashy maneuvers.

Introverted Feeling (Fi): Butler has a strong sense of honor. He is almost completely loyal to Artemis but he also respectfully objects to "distasteful" jobs, like kidnapping Holly. As a bodyguard, Butler has been taught to never grow attached to "the principal" (Artemis) He pretty much throws this rule out the window, developing a strange brother/father relationship with Artemis.

Extroverted Intuition (Ne): Butler typically likes to rely on hard facts, not supposition. However, when in tough situations he works on instinct, intuitively tying experiences in the present to his Si experiences without much conscious thought.
