Fire Emblem: Fuuin no Tsurugi

The first GBA entry in the series, featuring Roy from Super Smash Bros. fame.

Unused Enemies

 * William appears to be an unused boss, with a similar portrait to Roberts (a mini-boss who appears in Chapter 11A, in Hard Mode).
 * Idoun only appears as an NPC in the final game, but has some basic Shaman stats. This unit description reads "The Priestess of Darkness ordered by Zephiel to liberate the world". If hacked into a battle, she uses a generic palette.

Unused Classes

 * The Divine Dragon class: It is basically Fa's transformed state. However it has a glitchy map sprite and no battle animations.
 * Female Mercenary: Has an alternative map sprite (which looks a bit like a Myrmidon), but no battle animations.

These have very glitchy map sprites and no battle animations.
 * Social Knight
 * Paladins

Unused Items

 * Watch staff: A recurring item in the series. It's supposed to reveal rooms hidden by roofs (like the ones in Chapter 6), but it doesn't do anything in this game.
 * The Demon Dragonstone: It works identically to Idoun's Dark Breath, but bestows stat bonuses so maybe it was intended for a Mamkute version of Idoun. It was listed under some of the official guidebooks.
 * The Bridge Key: Useless. There are no drawbridges in this game.
 * Blizzard tome: It was going to be another long-ranged Anima tome, but was replaced by Fenrir.

World Map Names
There are English graphics for unused place names from the World Map. They are Phestos, Siene, Alesia, Terina, Calach and Regia.
