Arden Koilos sees herself as the control subject in the science experiment called life. Often labeled as "boring" and "predictable", Arden Koilos keeps her wild and experimental side reserved for pet projects. This boring lifestyle leads to her being considered anti-social and when she does join others, instead of relaxing she prefers to keep quiet and observe.

Arden Koilos can be very protective, and when any of her friends are being bullied or threatened, she will step in to defend them. This can get Arden Koilos in trouble when she refuses to back down during these exchanges, and sometimes has trouble discerning between friendly teasing and intentional insults. However, because of this fierce loyalty, her friends know that no matter what, Arden Koilos will be there for them.

The Sith rely on their passions to give them strength. Arden Koilos thinks inwards, only of things that matter to her, and always does what is in her best interests. She feels nothing about hurting others, or exploiting opportunities, and believes herself to be special, and above all others.

While generally laid back and more than happy to offer a quip of sarcasm, Arden Koilos's entire demeanor changes once combat begins. She becomes focused and quiet, with her smile replaced with a look of grim determination.

Where most err on the side of caution in a confrontation, Arden Koilos prefers to charge in head-first. While others may skirt a battlefield or keep their careful distance, Arden Koilos rushes in with devastating attacks with seemingly no regard for safety, relying upon instinct and possibly armor to protect her from dismemberment and death during her all-out attacks. Arden Koilos is a force to be feared on the battlefield, leaving a trail of death and destruction. However, Arden Koilos's blood-hungry ways put her in far more danger than the normal combatant, often resulting in needless injury and suffering, trading safety for pure offensive ability.

When it comes to a fight, some like to posture, some like to act tough, some like to dance around and go through all sorts of fancy footwork. Arden Koilos? Arden Koilos doesn't bother with exotic battle stances, intricate maneuvers, or super-secret tactics. Arden Koilos, when cornered into a fight, prefers the ancient technique of a good kick to the nuts. And if that won't work, either because the enemy is a woman or has balls of steel, Arden Koilos isn't beyond pulling a few more cheap tricks out of the bag. Granted, Arden Koilos won't be winning any medals for nobility or any prestige for a unique fighting style or a superb maneuver, but Arden Koilos will still be winning, the best and most dirty way she knows how.
