Alrighty, so I decided to redesign Kleiss because....reasons....idk.
hair- much longer and evened out, as well as more white streaks like real hair.
face/body- thinner and more sunken in features, as well as darkened sagged eyes to add a more decrepit look. He is practically a plant zombie. Plus some pointed ears because they are sexy.
attire- replaced the maroon military coat (seriously where do you get something like that?) with his old lab coat, tore half of it off and added dirt and blood splatter. Belt straps to keep it up. No shirt, both jacket and shirt are so his arm has more mobility. blood and bandages because hey, his fucking arm got blown off.....where do you think the metal one and the scars and his chest plate came into play. He needs them to keep him together and alive. Purple cargos replaced with actual military cargos, because WHERE THE FUCK DO YOU GET PURPLE MILITARY CARGOS IN A WASTELAND??? whykleisswhy?areyousecretlygay?pleasesayyesomgtheshipsiwouldsail. No shoes, so he can feel the earth (duh Van Kleiss means Of the Earth, plant powers derp) leg bandages are to keep his pants up.
gauntlet- made of mismatching metal parts and wires as well as his vines, making up the res of the missing bones and muscle groups due to the loss of his arm. more acutaly scrap bio-mecha like it should be.
eyes- yellowed and pupiless, due to loss of spirit and rest
nails- longer and dirtier
And there you have it!!!
