I guess someone beat me to the topic already....oh well.Here is why i think she would be great in brawl.
1.History
During the release of Super Smash Bros. Melee,one of the characters that were unlockable was Marth from the first and third Fire Emblem games.do to the fact that it was a practically unknown franchise,people felt skeptical about his appearance in smash bros.it was soon that the curriosity of the smash bros. players expaned to wanting to know about the Fire Emblem franchise.It was soon after that Fire Emblem 7,the first Fire Emblem game to be released in the U.S. hit the shelves of The U.S. and other eastern contries.Over a month later the game is very succesful,it featured the story about you and Lady Lyndis going on a search for his grandfather,who was betraid,and left for dead.When you encountered your first attack upon the enemy,Lady Lyndis showed her amazing speed and blade skill,it was hard for the opponent to land a single hit!!!When she lands a critical hit she is even more amazing as she warps into thin air and executes consecutive slashes upon the enemy,and you couldn't even see her,then she slides out of no where,putting her Manni Kati back into her sheath,now that is cool.as you progress through the game and level up lyndis,you get an item called the heaven seal.The item allowed you to level up any lord character you wanted.
When you level up lyndis with the item...wow,talk about a knight in shining armor,she has gone through a wardrobe upgrade and a skill upgrade,not to mention she could also use a bow!!Lady Lyndis is probably the most well known Fire Emblem character in the U.S. and Europe.This is just one reason to consider her in smash bros.
2.Fire Emblem has made a great establishment in the U.S. and Europe.
After the first Fire emblem game was released,many other Fire emblem games have been released as well.Such as,Fire emblem the sacred stones for the GBA and Fire Emblem path of radiance for the GCN.Due to this Fire Emblem characters have gotten popular to this country and others.But of all the characters in the franchise,Lady Lyndis stands as the most popular Fire Emblem charcter due to the fact she is the first to be exposed to Europe and the U.S.
3.Breaking the boundry of Sexes in Smash bros.
One of the thing that is of concern about Smash Bros. is the lack of Female characters.Due to the fact that she is the first lord in this country and eastern contries,and she is also female,it would greatly appeal to alot more people,and female players alike.
4.Unique fighting style.
Lyndis is no ordinary swordswoman,she uses an Eastern shinobi style,which is quick,swift,and deadly.She could also use archery as an alternation between melee combat to long range combat.Due to this she would have a great move set in Smash Bros.
