During their trip on a Salvation Front ship, Marcus notices Ix Nieves and Mileena Weiss floating in the ocean. He quickly jumps after them, rescues them and takes to a town on Sellund continent. Marcus stays with them for the next several days, keeping his eye on them and making sure they get proper treatment. In the World of Cryas and Eleth after Ix successfully seals the shimmera glass, Marcus appears and attacks the party.
