The veteran from Fire Emblem is back to stun the audience with his dazzling looks and lightning fast sword moves.
Marth's impact in Super Smash. Bros Melee was so great that two years later a Fire Emblem game finally made it out of Japan. Since the prince's international debut on the GameCube, he's been invited back to fight in Super Smash Bros. Brawl, and today the official website for Super Smash Bros. Wii U and 3DS updated with the announcement that Marth is back once again.
Fire Emblem fans outside of Japan finally had the chance to play Marth in his own Fire Emblem game in the DS title Fire Emblem: Shadow Dragon. Marth has been in a couple other Fire Emblem titles that have not released outside of Japan, but he does make an appearance in the 3DS game released earlier this year, Fire Emblem: Awakening. A masked swordsman identifies himself as Marth to the game's lord character, Chrom. Marth is a legendary hero in Awakening and should no longer be alive. (Spoiler!) This character is revealed to be Chrom's daughter, Lucina, from a horrible future when a ferocious dragon goes on a rampage to destroy the world.
Super Smash Bros. Melee introduced the west to Marth and fellow Fire Emblem lord Roy. Fire Emblem: Path of Radiance's lord Ike replaced Roy in Super Smash Bros. Brawl. If another Fire Emblem character is added to the mix of characters in the next Super Smash Bros., Awakening's Chrom would be likely to make the roster, but it would be nice to see Lucina added.
