Armor appearance and Equipment:
Heavy Troopers wear more durable armor than regular stormtroopers, which provides them a limited level of protection against lightsabers. The armor is completely self-contained and comes with its own air supply, allowing them to operate in most hostile environments. The joints of the armor have integrated servos which give Heavy Troopers artificially increased strength and speed. You can tell he is battle-forged just by looking at his armor suit, all the years of fighting engraved on it. It was slightly modified visually to be all black, as well as getting a new helmet to differentiate it from the common trooper uniform.

Appearance:
2 stripes of dark grey hair cut very short, line his head in the middle, distanced symmetrically, starting from the back of his head forward. His eyes are sharp, emotionless and have a dark grey color. He has a craggy face with strong jaws and a short trimmed circle beard. A light-saber scar is visible ranging from his left eye to beyond his left ear, a little into the back of his head.

He was brought in to serve the Empire when he was 9 years old. His training was hard and rigorous, testing his mental and physical capabilities to the limit. With hard training and good genetics his body muscle grew exponentially, also achieving a height of 178 cm at age 15. Besides him being in peak physical condition, he was also noted for quick thinking, exemplary show of loyalty towards higher ups and putting his mission above all. Even in team trials or versus matches in the academy, he never even took a second glance at his fallen comrades, he was always in the vanguard, being the first to charge and bait the enemies to focus him giving his comrades a chance to kill. In other times he charged forward, getting in close while his teammates covered him, giving him a chance to take things to close quarters where he had the advantage. Noting all these traits they decided to list him as a potential candidate on being an Imperial Heavy Trooper in the Stormtrooper Corps. So he was taken aside from the other cadets and trained separately with a selected other group of individuals. This training was harsher and unforgiving. By the end of all that, only he and a few others were given the honor of serving the Empire as a full fledged Imperial Heavy Trooper.
