I'm sorry to say this, but you can't. He can go up to level 30 (unlike other units) though! Hope I helped!
Blade of Light
Marth and Roy are both from the Fire Emblem series but are in different games. Marth is in: Fire Emblem: Ankoku Ryuu to Hikari no Tsurugi Fire Emblem: Monshou no Nazo Fire Emblem: Shadow Dragon Fire Emblem: Shin Monshou no Nazo - Hikari to Kage no Eiyuu while Roy is only in Fire Emblem: Fuuin no Tsurugi. He is seen in the secret ending of Fire Emblem: Blazing Sword as well. Also, both characters are in Fire Emblem Awakening, but only are available as add on content
A sword
Blade of Light.
No, Fire Emblem Sealed Sword is Fire Emblem 6. Fire Emblem 7 is the prequel to Sealed Sword and are separate games.
ragnell and falchion are not even in the same game. ragnell is in fire emblem PoR and RD. Wii and Gamecube. Falchion is in the ds game, SD. but ragnell is one of the best swords but Ike is the only one who can use it. it is the only sword you can use on the Black Knight. Falchion only Marth can use on the ds game shadow dragon.
There are two Fire Emblem games released for the Nintendo DS. However, only one was released internationally, which is Fire Emblem: Shadow Dragon. The one that was not released outside of Japan is Fire Emblem: Shin Monshou no Nazo ~Hikari to Kage no Eiyuu~.
in ninja gaiden dragon sword your character(Ryu Hyabusa) starts with the dragon sword.
It depends.. Some people say Ike is...Some people like me thinks that Marth is.. but really you can't tell...
A Sword for a Dragon was created in 1993.
A Sword for a Dragon has 480 pages.
Marth speaks Japanese because the game he is in, Fire Emblem, came out in Japan before Super Smash Bros. Brawl was released in the U.S. For his victory poses, he says: 1."Today, I have survived" (sheathes his sword) 2."This time it's my victory, isn't it?" (turns and spins his sword) 3. "There's no way I can lose" (sticks out his right arm) Hope that helps! Props to "The Brawl Page", a blog with the translations.
