Despite whatever all his other characteristics may convey, Necronis retains the air of a person that is confident, if not arrogant. Minor (and often, major) things in his body language - his walk, his stance, his expressions - reveal these feelings. At times, it seems he borders upon narcissism, especially judging from how much he enjoys his own company.

Through a combination of preparing, studying, and analyzing, Necronis creates detailed battle plans and tries to think two steps ahead of the enemy. At times, however, this can lead to Necronis creating complicated schemes that can baffle less intelligent subordinates.

Necronis has a tendency to be secretive and keeps to himself, relying on deception to conceal his motives and intentions. He is a schemer, and plots and plans against others carefully. When dealing with a confrontation, he will try and bluff his way out of trouble, or overcome obstacles with deliberate, covert actions.

Despite his line of work, Necronis still sees himself as a refined gentleman and will often put on a show of being haughty and arrogant to those he does not know. Necronis only lets the mask slip to show his more laid back nature to those he trusts. To those he dislikes, he will actually become even more insufferable as taunts and quips without any regard for who or what he might be offending.

Necronis vastly prefers ranged combat, taking every opportunity to use skills and Force Powers to disengage from melee and instead fight at range, so much so that he has become competent at staying out of melee in the first place.

Necronis seems to get his thrills, perhaps sadistic ones at that, from toying with his opponents. Some are content with simply striking down or injuring their opponent, but that is not enough for Necronis. No, he wishes to see his enemy descend into madness or kneel before him as a blathering mess; or even better, as a fresh new servant with a muddled mind. The Puppeteer usually forsakes outright hurting and maiming his opponent and focuses on illusions, mind tricks, and other wicked means of destroying a person.
