Extensive cybernetic modifications of Echo-1's body have allowed him to form a bio-technological symbiotic relationship with his battlesuit. His neural-interface chip and the connection ports on his extremities, shoulder blades, spine and neck regulate this symbiosis and allow him on-the-fly mental control of the armor's functions. This heavy armor holds it's own weight through cyber-muscle fibers, granting Echo-1 freedom of movement. The armor is an essential part of Echo-1's body, much like a cybernetic limb would be, and he never fights without it.

Deep medical scans of Kintan's body have revealed extensive genetic modification. He was genetically engineered in a lab to grow above average height, mass and strength while maintaining superior agility, begging the question of how exactly he was born. His muscles are on average 20% denser than a normal humans, allowing him to perform unbelievable feats of strength and agility on the fly. The genetic modification process seems to have had another unexpected effect. The tampering done on his genes has produced above average levels of midi-chlorians, making him Force Sensitive. Before joining Odan-Urr, Kintan's Force powers came instinctively to him, however after almost a year of training he has nearly mastered control of his abilities.

While he is a perfect, lethal and precise killing machine, Kintan's emotional and social intellect is still very underdeveloped. While he has great potential to understand people's emotions and complex social structures, he doesn't have nearly enough experience in these fields to allow himself to remain relaxed in other people's company. Thus he has an aura of social awkwardness to him that many people instantly recognize. Whilst he has a few individuals he can call "close friends", he mostly avoids unfamiliar people. He is also emotionally underdeveloped to the point where he has issues controlling his emotional responses in certain situations. He rarely smiles or laughs and when he does it always seems forced.

Echo-1's intellect far outmatches most of the average citizens of the galaxy. He was programmed through genetic engineering to out-think and out-maneuver almost any enemy he faces. His mind is a steel trap in and out of combat situations and many a mission has been accomplished successfully on account of his quick thinking. Improvisation is second nature to him and there is no task too hard, and no mission impossible. However due to the genetic tampering he was subjected to, medical experts have agreed that he will eventually burn himself out. The genetic program he was subjected to forces his brain to constantly operate at above average levels, allowing him to think on the fly. Echo-1 will likely still be young when brain death occurs.

Echo-1 lives by a simple rule - war never decides who's right, only who's left. The mission takes priority over survival because Echo-1 knows that giving one life to save millions is a small price to pay. Still he won't just throw his life away and fighting a vastly superior enemy intelligently is Echo-1's mantra. He will attack his enemy with with tempered intellect and reserve if they are strong and explosive excellence and might if they are weak, but he will never back down until he fulfills his mission. Should he die in the line of duty, so be it, but he will always complete his task - even if that means blowing himself up to ensure it is done.

Kintan is the true personification of war. Trained to operate in any environment on any planet, he is the perfect soldier and this reflects in his combat style. In single combat he will usually resort to his ranged weaponry, constantly moving to achieve new angles of assault to keep the enemy on his toes. If that fails, and the enemy closes the distance, he will resort to his knowledge of Teräs Käsi, coupled with his enhanced physical abilities, to bring anyone to their knees. He is still uncomfortable with lightsabers, but he does not shy from igniting the silver blade from time to time.
