Also known as: 大門大
The protagonist of Digimon Savers, a hot-headed self-titled street fighter and partner of Agumon (Digimon Savers).
Has a reputation for being disproportionately, almost superhumanly strong, as he repeatedly punches out Digimon the size of buildings and even destroyed Craniummon's spear, Claíomh Solais, with his bare hands. Some even joke that he's stronger than any Ultimate-level Digimon.
In English media, Masaru is referred to by the dub name Marcus Damon.
