The first scout of the pack, and the mate of Rusty. He was expelled from his previous pack after he fought the heir of the alpha about expanding their borders. He was proposing to expand their territory to find more prey easier in winter and to maximize the pack's size, considering there was a rival pack that surpassed their numbers, but they thought it was stupid and that there was enough food for winter. The discussion got so intense, that Marco bit the heir, action that exiled him. He didn't struggle much as a rogue, but he was still bitter about it. When he joined Shine Pack, he suggested Robin the same thing and, unlike his previous pack, she accepted it, and made him the first scout. When Rusty came around, he began to feel strange around him. He felt this way with his first mate, but tried to deny it. Still, he taught Rusty about scouting and grew fonder of him day by day. One day, Rusty proposed to him, and he finally accepted his feelings: he was in love with him.
