Marcus

Marcus ​is a playable character in Fire Emblem: The Blazing Blade and Fire Emblem: The Binding Blade. He is a senior knight of Pherae. In both of these installments he fills the part of the Jagen type character, beginning powerful but ultimately being outclassed by other units, along with taking an early advisory role to both Roy and Eliwood in their respective titles. He can recruit Harken and support with Merlinus.

In The Blazing Blade if he loses all his HP he will stay out of further battles, instead of actually 'dying'. This is due to his appearance in Fire Emblem: The Binding Blade; if he had died in The Blazing Blade, being alive later in the chronology of the Elibe saga would have made no sense.
