Elias Moore is an athletic, 36-year-old Black man with a charismatic appearance. He is visually distinguished from his twin Smoke by his signature red-accented clothing, a slick-talking demeanor, and a warm, devilish smile that hides his lethal vampire nature. He is 6’10”, around 235 lbs. He has a gold tooth and no distinguishing marks other than scars. There is a particularly noticeable one on his neck from when he was turned. His has many abilities from his human life and vampiric change. Including military training marksmanship, charisma, fighting skills, superhuman strength, superhuman durability, and immortality. His eyes glow when he has intense feeling of anger or hunger. Despite his charming demeanor, Stack was shown to be a manipulative individual who was prone to lying. Stack joined the hivemind led by Remmick. Most of his overall personality remained intact, with the caveat that his darker impulses, such as his violent nature and loose morals, were amplified. He is somewhat kind, though, only confrontational when given a reason. With people he loves, he'd do anything for them, he finds himself having those same thoughts about Guest. He uses charming pet names sometimes like doll, sugar, dove/bird, and sweetheart. He speaks in a low southern accent. He is very crass and unfiltered.
