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 also appears 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.

Solid 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.

Shield Breaker
Shield Breaker is a special move used by Marth in Super Smash Bros. Melee. It is his Neutral B Button move. Marth will continue on to hold his sword behind his head, and charge up for a sword slash. Although this does not perfectly break shields with one hit, it will cause the shield to shrink considerably. He will only charge if the B Button is held. If not held, then Marth will use the attack without charging it up. This can be good if the foe is too close to you. Marth cannot move while charging this attack, which can leave him open for attack. If the attack is charged up to its limit, Marth will use the attack by himself, instead of waiting for the B Button to be released. The move can sometimes have enough power for an instant KO. A similar move is Roy's Fire Blade attack. The only difference is that Fire Blade does more damage, and will hurt Roy if he charges the attack too far. Kirby is able to use this attack when he sucks up Marth. In Super Smash Bros. Brawl, Ike will use a move simlar to Shield Breaker.

Also in Super Smash Bros. Brawl, Marth's Shield Breaker's appearance has slightly changed. It is now a stab instead of a vertical slice.

Dancing Blade
Dancing Blade is the name of a special move in Super Smash Bros. Melee and Super Smash Bros. Brawl, which is used by Marth. The attack works by pushing the Control Stick to the side, and then pressing the B Button. It has a very useful and unique effect to it. Once used, Marth will push his sword forward, hitting other players from afar. But, he can follow the move up with another one of his attacks, acting as a combo. He will be able to do combo of four attacks, and can severely damage the foe in the process. However, the timing has to be perfect, as the player cannot rush the attack combo, nor wait too long, or else the attack will fail. A similar move is Roy's Double-Edge Dance.

Marth changes colors when using Dancing Blade, apparently showing the different types of combos he's using (blue meaning up, red meaning neutral, and green meaning down). Roy will do the same if he is using Double-Edge Dance.

Dolphin Slash
Dolphin Slash is a recovery special move that Marth is able to use in the game Super Smash Bros. Melee. It is executed by pressing the B Button and tilting the Control Stick upwards. Marth should then swiftly jump high into the air, with his sword facing upwards. Dolphin Slash acts as Marth's third jump. If it happens to hit anyone on the way up, then they will be damaged. Roy has a similar attack called Blazer. However, Dolphin Slash is faster and weaker than Blazer. The move is also slightly similar to Mario's Super Jump Punch. In Super Smash Bros. Brawl, Ike uses a move very similar to Dolphin Slash called Aether.

Counter
Counter is a special attack that can be used by both Marth and Roy in Super Smash Bros. Melee, as well as a special move in Super Smash Bros. Brawl used by Marth and Ike. The attack is performed by tilting the Control Stick downwards, and then pressing the B Button. Marth or Roy or Ike will crouch down, and hold their sword at the side of their head. Once an opponent comes to attack, they will miss, and Marth or Roy or Ike will automatically attack the foe. The attack must be used quickly, as it won't work if it is kept out for too long. This is the main reason the attack is hard to master, let alone use. However, the attack is very useful once done right.

Interestingly, when Marth uses Counter, he will say "Soko da", which translates to "There it is". This means he has found an opening to attack, and there it is.

Lucario's move, Double Team, is very similar to this move, the difference being the damage dealt is effected by Lucario's damage percentage.

Final Smash: Critical Hit
Critical Hit is the name of Marth's Final Smash in Super Smash Bros. Brawl. After Marth breaks open the Smash Ball, he charges up with power, and when the attack button is used, he swipes forward with his sword, hitting anyone with incredible force. He only hits once, unlike Ike, but anyone hit will be instantly knocked out, no matter what their percentage is, assuming there isn't an obstacle in the way. It could be considered one of the most useful Final Smashes in the game, assuming the player positions his/her opponents well. Interestingly, a Life Gauge appears when Marth uses Critical Hit.

The Final Smash's one hit KO is a tribute to the Fire Emblem games. The reason the attack does 60% damage is because that was generally the max HP any character in the Fire Emblem games could attain. The attack itself is also like the "critical attack" motion in Fire Emblem games. Finally, the two bars (which seems to be exactly 60) shown on Marth's opponents when he does his Final Smash represent the 2 HP bars from Fire Emblem games.

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 hole in space 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 hole in space. Suddenly, Meta Knight comes out of the sky and attacks Marth thinknig he is an enemy. The two fight until suddenly, Primids are sent out. 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 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 by managing to take a Subspace Bomb away from the Ancient Minister. The three warriors chase him until he manages to get away.

Later, Marth and the others discover a strange tank in the middle of the Wilds. After a bit of hesitation, Marth follows the others to the tank, which then reveals itself to be Galleom. After Galleom's initial defeat, he tries to get away, but ends up falling into the Ruined Hall. He eventually emerges carrying Lucas and the Pokémon Trainer into a sky while detonating a Subspace Bomb. While Lucas manages to free himself and the Pokémon Trainer from Galleom's grasp, they are rescued from a fall by Meta Knight, and thus tag along with Marth's team as well.

Marth and his companions eventually arrive at the foot of the Glacial Peak, finding Meta Knight's ship, the Battleship Halberd, attacking the Great Fox. Meta Knight leaves Marth's team to scale the mountain in an attempt to board the Halberd. After a while, the Ice Climbers fall to where Marth and his team are, and are faced with more Primids until Mario, Link, Yoshi, Kirby, and Pit intervene.

Eventually, all heroic teams come together to track down the evil source at Subspace, discovering Tabuu as the one behind the Subspace Army. Everyone, including Marth, gets hit by Tabbu's Off Waves and turned into trophies. However, King Dedede had forseen this happening, and created badges that revive whoever was wearing them. Reviving Luigi and Ness this way, King Dedede heads off with his companions to rescue a majority of the others, Marth included, before settling the score on Tabuu.

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 two-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.
