Physical Description:
 Before augmentation Jack was small. One of the smallest in his class of nearly 400. This led to him being bullied and he has several scars along his face. After Augmentation he grew to be one of the tallest in his class. Standing at just over 6'6" out of Armour. Jack keeps his hair quite short and dyes it jet black. He has brilliant blue eyes and slightly tanned skin. 

When out of armour he always wears standard UNSC combat trousers and a colourful shirt of his choice. Much to the disapproval of his superiors.

Biography: being born in the outer colonies, Jack was destined to be a farmer like his father and grandfather before him. That all changed when the covenant arrived. His planet was reduced to glass in a matter of days and he was one of the few to make it out on a shuttle. He was then contacted by Franklin Mendez and was asked if "he wanted to get back at the bastards who did this"
Jack of course agreed. He went through the same augmentations and training that the rest of his class did and is one of the few in gamma company to be outfitted with Mjolnir class Armour.
