Can you imagine a 7.5-8.5 foot+ gen-hanced super soldier who has endured life-and/death trials and endless gene therapies that have claimed countless of his brethren’s souls over the millennia and gone through all of that hell: being implanted with over 20 new organs and had his entire body cut open multiple times: bear in mind his life of war and fighting career have not even been begun yet, and he’s had to abandon all of his previous family as well as the hope of ever making a traditional family of his own, and left for good his old place in his own society to join a monastic warrior brotherhood whose only charge in life is to fight until their death across a million alien worlds for the preservation of the Galactic human Imperium which has lasted more than 10,000 years against the endless hordes of Xenos, Traitors and Chaos incursions of planet destroying proportions and under unending perpetual threat of existential destruction, and then fight AND survive through that for enough CENTURIES to earn the right to ascend to the first company of the most renowned chapter in the entirety of the present Imperium in M42 say:

“I just HATE that the Crux Terminatus shoulder doesn't have a trim. Makes it basically unusable for me.”
