Marth

Marth is the Prince of Altea, from the Fire Emblem series. He is also a playable character in the Super Smash Bros. Series, along with Roy and Ike, other characters from the Fire Emblem series.

''Super Smash Bros. Series
Marth made a surprise appearance in the game Super Smash Bros. Melee. He was an unlockable character, and could be unlocked by simply beating Classic or Adventure with all the 14 default players, and then beating him. Marth is a fast character, but lacks power, and is unusually light, for all the armor he wears. Although most of his moves aren't dreadfully powerful, his Shield Breaker move can send the foe flying if it is charged to the most.

The main difference between Marth and Roy is that Marth is faster and lighter, and Roy is stronger and heavier. Marth will also appear in Super Smash Bros. Brawl, alongside fellow Fire Emblem character, Ike. He is unlocked by either playing 10 Brawls, beating Classic Mode on any difficulty, or by meeting him in The Subspace Emissary. For the first two methods, he will be fought afterwards, and must be defeated to be unlocked. Marth's Final Smash is Critical Hit, a single hit that instantly kill whoever it hits.

Snake Codec conversation

 * Mei Ling: Snake, have you heard the saying "Politics makes strange bedfellows"?
 * Snake: Don't tell me that's a Chinese proverb.
 * Mei Ling: Err, no... It means that when the going gets tough, you might need unexpected partnerships in order to succeed. Marth was a prince whose kingdom was usurped. He didn't even have an army to fight with him. But as he battled his way forward, he found new allies to fight at his side, and in the end, he was able to reunite the war-torn land of Altea.
 * Snake: So he built his army from the ranks of his defeated enemies...
 * Mei Ling: Marth did his share of fighting, too. Even when he had an army, he was always alongside his men in the thick of battle. Then he was betrayed by one of his most trusted friends. I can't even imagine how that feels...
 * Snake: I can.

Role in the Subspace Emissary
Marth is seen standing over a castle watching down at the desert. Marth sees the Subspace Bomb exploding in the distance and creating a large purple explosion that remains in the middle of the desert. Marth takes out his sword and walks over to it to expect it, while defeating some Primids a long the way. He finally is in front of the large purple explosion. Suddenly, Meta Knight comes out of the sky and attacks Marth thinknig he is an enemy. The two fight until suddenly, Primids grow out of the ground. Marth and Meta Knight both cut the Primids in half.

Marth and Meta Knight look at each other surprised and realize they are in the same team. Primids keep emerging from the ground as the two stand back to back seeing them grow. They then charge at the Primids and attack them. Later, Ike gets to join the party.

Classic
''The betrayed prince of the Kingdom of Altea, the blood of the hero Anri flows in Marth's veins. He was forced into exile when the kingdom of Dolua invaded Altea. Then, wielding his divine sword Falchion, he led a revolt and defeated the dark dragon Medeus. Afterwards, Altea was annihilated by King Hardin of Akanea.

Adventure
''Marth is a magnificent swordsman. While his swordplay is faster than that of Link, he lacks power, and his quickness if offset by a marginal endurance. His Shield Breaker gains power the  longer it's held. The Dancing Blade combination uses both the Control Stick and the B Button to produce a series of up to four attacks.

All-Star
''The tip of Marth's blade causes the most damage, so you should try to create adequate distance between you and your enemy to gracefully strike with that point. Marth's dolphin Slash is fast and powerful, but it leaves him vulnerable upon landing. Marth uses Counter to block a foe's attack and deal a return strike. If you're fighting a Counter-happy Marth, grab him.''

Marth
''The prince of Altea, in whose veins the blood of heroes runs. He and a small group of stalwarts fought to free Altea after it was invaded by the kingdom of Doluna and the dark dragon, Medeus. With his divine sword, Falchion, he fought and defeated Medeus. However, Altea was then invaded by King Hardin of Akaneia and eventually destroyed.''

Critical Hit
''Marth's Final Smash. He thrusts his sword skyward, then rushes to meet his targeted enemy with furious speed. The blow he strikes is so powerful that his foe is instantly launched off the screen. As in Fire Emblem, a window appears that shows the character's hit points dropping rapidly to zero--but this is just for effect. Smash Bros. does not use a hit-point system.''

Trivia

 * Marth and Roy only speak Japanese in all versions of the game. This is because their only appearances were in Japan. Marth is voiced by Hikaru Midorikawa who also voiced him in a 2 episode OVA.
 * Marth and Roy were meant to only be in the Japanese version of the game, but they received a lot of attention from Nintendo of America, so they were kept in. American fans also became interested in Fire Emblem, because of Super Smash Bros. Melee, and it helped Fire Emblem enter the United States.
