Character description
Marth is the prince of Altea and the main character of the first Fire Emblem game. In the first game, hundreds of years had passed since Medeus was slain in Akaneia. Once Medeus is resurrected, he rebuilds his land of Doluna, ready to invade Akaneia once again. After an attack from Doluna, Marth is forced into exile in the island nation of Talys and home of his childhood friend, the princess Shiida. His father, Cornelius, is killed due to a betrayal by his ally Jiol, the King of Gra and Gharnef, and an evil Pontifex and a devout follower of Medeus; the sword Falchion is taken by Gharnef, and Marth's elder sister Elice is taken hostage. With the help of the Altean knight Jagen, Shiida, Aurelian commander Hardin, Red Dragon Princess Minerva, and others, Marth embarks on a quest to defeat Medeus, reclaim the kingdom of Altea, and rescue his sister. Marth meets Nyna, the princess of Akaneia — the most prominent kingdom — who gives him her country's national treasure, the Fire Emblem. After Gharnef is defeated by one of Marth's allies, Marth obtains Falchion which he uses to defeat Medeus. Afterwards, he proposes to Shiida.

In Super Smash Flash
Even though Super Smash Flash is based off of Melee, which Marth's and Roy's appearance in Melee sparked enough interest for Nintendo to release the Fire Emblem series internationally. Marth was not included in Super Smash Flash like other characters such as Donkey Kong, Peach, Yoshi, Wario, Bowser, Ness and Falco due to not having any sprites on the internet at the time the game was being created.

In Super Smash Flash 2
Marth appears in Super Smash Flash 2 with his sprite design based on his appearance in Super Smash Bros. Brawl; while his hair is modeled after his its appearance in Fire Emblem: Awakening. His moveset is taken directly from Brawl.
