Marth is back for Super Smash Bros. for Nintendo 3DS and Wii U for his third time. He will be unlockable once again for SSB4. At this time around, he's a default character. Using his grace and finesse, Marth can slice and dice any character.
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 who's 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..."
Marth is difficult unless you have an explosive projectile. With this you can attack from a distance and nullify his Counter. If you do not have an explosive projectile, fight at close range and use throws to defend against the Counter. Aerial attacks also work well to avoid Marth's throwing ability.
In Melee and Brawl, Marth speaks Japanese. This may be because the Fire Emblem games that Marth has been featured in haven't been released in English. However, those games have been confirmed for release in North America within the next year.
