Rosh Nyine possesses a cold and completely uncaring demeanour. This will manifest itself in the fact that when push comes to shove,Rosh Nyine will just as soon leave a struggling ally behind rather than put themselves in danger. While this may ensure his survival, it often leaves him as an outcast amongst his peers.

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

Killing has never been a problem for Rosh Nyine; and he kind of enjoys it now, if he is honest. Killing's what Rosh Nyine does, and he likes what he does.

Rosh Nyine tells it like he sees it, when he thinks it; and he doesn't try to sugar coat what he says.

Rosh Nyine 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 Rosh Nyine. 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.

Rosh Nyine wears out his opponents through use of the Force, agility, and evasion. Once he has sufficiently tired his foes through the Force, physical, or mental assault, he quickly tries to find a means of cleanly and swiftly dispatching them - usually resulting in a somewhat risky all-or-nothing attempt at a deathblow.
