Anima was experimented on, by both himself and Macron Sadow, throughout his lifetime. The goal was power, attained at the price of pain and loss. His body was sacrificed in many ways, pain molding his flesh and psychosis rattling his mind. Trying to find his own way, he delved deeper into his self-mutilation until corruption sought to claim him fully. In severing his mistakes he lost a portion of his body, and became detached from humanity as well.

Anima lacks the capacity to care for anyone or anything. This causes him to appear cold to even 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. Life, love, passion, all hold no meaning to his cold, calculating mind. Still, he does not lack a certain fondness for sarcasm, utilizing it as a standard form of communication.

Holding his cards close to his chest doesn't even begin to cover things for Anima. 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 Anima's desired direction.

The dark side corruption plaguing Anima leads to a more than unstable personality. His typically cold and calculating demeanor can suddenly shift into utter 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 needs. However, there are no defined intervals for his condition, turning him into a completely unpredictable foe and ally alike.

Anima cares only for the battle. Whether it be against multiple foes or a singular target, he will forge head on into battle. 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, Anima 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.

Anima 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.
