Marth

Marth is the King of Altea from the well-known Nintendo series, Fire Emblem Shadow Dragon and Fire Emblem Mystery of The Emblem. Even though Fire Emblem is the origin of Marth, he is also known for being featured in the Super Smash Bros. Melee and Super Smash Bros. Brawl. as a unlockable character, mainly due to the fact that the Fire Emblem series never released outside Japan until after the release Super Smash Bros. Melee, though there was still a Japan-only title on the Nintendo DS, Heroes of Light and Shadow, a remake of Fire Emblem: Mystery of the Emblem Book 2.

In M.U.G.E.N, Marth has been created by an unknown creator and edited by Pingurules. He also appears as a striker for Yu-Toharu's Hatsune Miku.

Unknown Marth
Created by an author who chose to remain anonymous (leaving the original creator's name behind), it's no big surprise that this version of Marth is not the slightiest bit decent, and not only because the character is a spriteswap of Warioman's Tom, which makes Marth another poorly made character. Strangely, he summons Odie and the CLSNs are not even edited, making him supremely cheap.

Omegabros6's Marth
Before Pingurules edited Unknown's Marth, Omegabros6 had already made one. It uses Kung Fu Man as a base and it has very slow A.I.

Pingurules' Marth Edit
This edit of Unknown's Marth by the fixes of all the problems that were present. His Odie summon was changed into a Roy summon and he fixed the CLSNs while adding new ones where it is supposed to be. Pingurules also added four hypers and a Super Smash Bros. Brawl soundpack. His AI somehow became much weaker, probably so weak that he can only land one or two attacks on the player before he is defeated, providing the player is experienced.
