While Calvo is very aggressive in combat, he has combined his knowledge of Teras Kasi with basic knowledge that a moving target is harder to hit. While unarmed, or with a lightsaber Calvo will jump, duck, spin, change direction, and do anything else to change his height and direction. While this helps for large groups, he is aware that this is useless against a single opponent, and will abandon this tactic when facing someone one on one.

Calvo has taken up Guerilla tactics in almost everything. In combat he will use the environment, and all of his abilities to his advantage. He will never engage until he knows his opponents strength's and weaknesses.

Calvo's affinity with the beast control ability has influenced his mind. He has started to think like an animal. His mind is not damaged, he has just become more cold and careless. Losing his optimism during the 11th Great Jedi War, from which he participated in, he began thinking of those he does not feel are important, are fodler,and he would let them die without a second look.

Calvo, now having killed his primary enemy, has begun to doubt the dark side. Believing it was nothing more than a waste of time, he doubts his true path. Having heard of the Grey Jedi, he has tried to become one of them. He hesitates to ever try and learn any dark side attacks, and is hesitant to join the Light side, as he enemy was a Jedi of her own right. He walks the path of Balance, though when push comes to shove, he is truly a dark Jedi.

Learning Teras Kasi in the 11th Great Jedi War, Calvo has devoted himself to combat. he has given up his previous control of the battlefield for brute force. Though his study of martial arts, light saber combat, and his own ability to control beasts, Calvo makes a powerful combatant, though at range he is near useless. Calvo will often combine his rage, and his beast control to battle, though will lose control more often.

Having gained his own small squad of five soldiers from the Ascendant Legion, Calvo is never truly alone. One member of his squad is always with him, though they switch out constantly. This does help him in combat, though he will always try to keep his squad safe. He will risk his life for his squad, and they will do the same for him.
