Fire Emblem: Monsho no Nazo (ファイアーエムブレム 紋章の謎, Faiā Emuburemu: Monshō no Nazo, Lit. "Mystery of the Emblem"/"Secret of the Crest") is the third installment of the Fire Emblem game series developed by Intelligent Systems and published by Nintendo.
Marth was included as an unlockable playable character. His inclusion, along with Roy's, gave the series the worldwide exposure that led to the decision to release future Fire Emblem installments globally.
Monsho no Nazo is the only Japan-exclusive Fire Emblem title listed in the North American release of Brawl not to receive an English translation. Nintendo's policy of preserving as many original Japanese aspects as possible for their "Import" Virtual Console releases has led some to speculate the title's lack of translation may be signs of intent for an upcoming release abroad.
