Marth is a kindhearted, talented, yet incredibly idealistic leader who takes up the sword in the name of his fallen brethren and fellow conquered Archaneans. More than capable as a ruler, he holds himself to an immense sense of duty; willing to push aside his own grief to comfort his Altean people upon their first liberation in the War of Shadows. In sallying forth to aid Princess Nyna, he also honors the historic ties between his country and House Archanea as inducted by his ancestor Anri. Marth's idealism stems mostly from the powerful desire to keep all, if not at least many, of his allies alive throughout his two wars. This is a natural result of Marth's sorrowful experiences with his elder sister and vassal sacrificing their safety to ensure his escape. Said idealism takes a toll on him, however, as he melancholically visits the graves of those whom have been killed as seen in New Mystery of the Emblem. While Marth would prefer avoiding a fight, he is more than willing to lay down his life alongside his comrades.
