Atra believes in only one constant, one objective; the galaxy must be cleansed, and born anew. To this end, he has made it his life's mission to eliminate all conflict from existence, under the title of "Xue Long". As the seasons change from the spring of life, to the decay of winter, so too does he embrace the coming snow. He is the architect of death, offering it as a kindness so that life may begin again, unimpeded by the trappings of conflict. Even his own life will be sacrificed if needed, so long as he follows his path.

Atra is unable to properly process his own emotions, which often causes him to appear cold and introverted. He can come across as confrontational and jovial within the same breath to his friends, and he often takes things at face value. Subtlety goes over his head more often than not, as he views the world with only passing interest and doesn't care to read into anything unworthy of his time. Life holds no meaning to his cold, calculating mind, only his own desires and goals. Still, he does not lack a certain fondness for sarcasm, utilizing it as a standard form of communication almost relentlessly.

Holding his cards close to his chest doesn't even begin to cover things for Atra. One could say there is never a single action he takes that doesn't have multiple intentions. Even when apparently going out of his way to help an ally, it would be a safe bet that he, and he alone, benefits in some way. This apparently selfish nature is misleading, as it is not greed but his singular tenacity towards the completion of his goals. No action need be wasted if it always ends with a step in Atra's desired direction.

The dark side corruption plaguing Atra leads to a more than unstable personality. His typically cold and calculating demeanor can suddenly shift into apparent insanity, dominated by a purely animalistic, bloodthirsty drive whilst retaining his cunning. These animal characteristics are ever present, manifesting in the form of growls, snarling, and other traits that would be attributed to someone raised by wolves so to speak. He is ruled by his baser instincts, giving into whatever the urge that comes over him - whether that means devouring his fallen prey or fulfilling his present urges. However, there are no defined intervals for his condition, turning him into a completely unpredictable foe and ally alike.

Atra cares only for the battle. Whether it be against multiple foes or a singular target, he will forge head on with glee. This desire often causes him to require his opponents be at their best before engaging them. If they so require it, he will provide them with a weapon. While he requires this even starting point, Atra will not hesitate to take advantage of any weakness he perceives once the fighting starts. In fact, it is his aim to poke holes in his enemy's defenses, exposing their flaws so that they may learn from it, if they survive, and offer him a greater challenge. He is utterly relentless, fighting anything that comes before him, friend or foe.

Atra weighs all enemies equally, at first. Through combat he judges the character and worth of his opponent and as such must be a blank slate himself. He closes off his emotions and leaves himself receptive to those of his enemies. The actions he sees there determine his own, causing him to fight honorably or otherwise. In this way, he mirrors the mindset of his opponent and decides if they are worthy of being killed or not. Due to this one on one nature, he can succumb to tunnel vision and lose sight of multiple targets.
