Marcus Damon

Marcus Damon (大門) is a fictional character in the Digimon Data Squad series. His name, Masaru, means Victory in Japanese.

He is the first human lead of any Digimon serial, excluding C'mon Digimon, that doesn't wear goggles. Marcus is also the first and only human protagonist to physically hurt Digimon on a regular basis.

In the Japanese version, when referring to himself, Masaru adds "" (様) onto his name.

Marcus' Japanese name is probably also an intended pun as it could be read Daimondai (大門大), appropriate for his hot-headedness and tendency to act before thinking.

Marcus's birthday, April 2, is the same day Digimon Savers started in Japan.

Story
It should be noted of Marcus's importance to the team: he is often the one to finish a major opponent. Some examples are when he smashed SaberLeomon's fang, blasting his DNA through Belphemon's chest, destroying Craniamon's shield and shattering Yggdrasill's true form. These are all performed from when he punches the opponent with immense strength.

Marcus's DNA Charge seems to possess great potential: the most noticeable moment was in episode 45 when his revelation that his friends believed and trusted him to stop King Drasil/Spencer Damon, it created an aura that protected him from MirageGaogamon's Full Moon Blaster and Rosemon's Forbidden Temptation; instead of hurting him, it simply collided with the aura and propelled Marcus upwards (he had been falling at the time).

Five years later, he and Agumon still wander the Digital World, challenging strong Digimon.
