Mark has metallic black hair and pale, icy cyan eyes. He wears dark grey clothes and has pale skin. He is unusually tall.
Mark is clever, witty, and kind-hearted. He makes very few appearances and usually sticks to the shadows of the forests. During a tornado when he was about 18, a child accidentaly ended up in his area and adopted her, naming her Amanda. He is quiet, similar to his forgotten brothers Herobrine and Ender Steve. Few people know him, and the people that do end up finding him leaving soon after they see him. Mark is very stealthy and can creep up on almost anything, let alone the Creepers. Jumpy and quick-footed, and will not give up anything he owns without a fight.
