In the Fire Emblem universe, or perhaps for the people that played it, Marth is a legend. Why so? Simple - because it was with him that the series started with. He went on to star in a sequel, in the remakes and in the Smash Bros game - wherein his character gained attention from the worldwide audience - which of course resulted with the first ever Fire Emblem game being localized for the whole world. Now, Marth's back in Fire Emblem: Awakening. Take a look below.
If the video above still doesn't get you excited, I doubt anything will. Anyway, as you saw, Marth looks like either a friend or a foe. But Siliconera noted that the Fire Emblem: Awakening takes place many many years after Marth's game, but that face and physique of his doesn't even suggested that he has aged.
