Marx (マークス) is a playable character in Fire Emblem If. He is the eldest child of the Nohr royal family. He is voiced by Katsuyuki Konishi in the Japanese version.

Profile
Marx is the eldest child of four in the Nohrian royal family. He eventually received another younger sibling when the Avatar was adopted into the family. Although taciturn, he has an honest personality. For the sake of the kingdom, he follows his father's, the king's, intentions and cares deeply for his siblings. He wields a sword wreathed in dark flames.

He's at one point seen questioning his father's motives, stating; "Father cannot be evil!"

At the end of Chapter 6, depending on the side the Avatar chooses, a different scene will unfold. Choosing Hoshido will cause Marx to attack the Avatar, labeling them a traitor.

Etymology
Marx is a German surname. Some claim the Jewish German version of the name is an acronym composed of the first two letters of the Hebrew Masiach with a Hebrew rendition of the Latin Rex (cf. Jewish German surname Katz).
