Marcus

Marcus is a minor antagonist, a playable character outside the main storyline, and the main antagonist within Trey's storyline of Duel Masters: Cobalt. He serves as a rival towards not just Trey but also Flynn, who serves as Knight's counterpart to Marcus.

He is a duelist of the Darkness civilization.

Description and Personality
Marcus' attire is an unusual one: his choice of fashion clothing borrows elements of a BDSM fetish with a blindfold covering his eyes. He has what seems to be silver hair with violet highlighting.

Marcus suffers from an Superiority Complex, as he has a nack for telling people that he "is" better than them. Shown by Rusty, Marcus also has a somewhat amount of charisma. All this changes during the aftermath of the final story.

Trivia

 * Marcus' name comes from the Roman god Mars, more popularily known through ancient Greece as Ares the God of War. Strangely, this does not fit his choice of Civilization.
 * His name may be a reference to the movie Underworld, which there is a vampire named Markus.
