Gotoh

Gotoh (translated Gato in the Japanese versions) is a member of the Divine Dragon Tribe and a Bishop of great renown, known as the White Sage. He was one of the few Divine Dragon survivors of the war against the Earth Dragons and lost the ability to take dragon form. He was later ordered by Naga to guard humanity after Naga's death. When Medeus and Doluna began their war against humanity, Gotoh led Anri to the Ice Dragon Temple where Anri claimed the Falchion he would use to defeat Medeus. Gotoh later founded the nation of Khadein‎ and trained two pupils: Miroa and Gharnef, both two students striving for justice. But since Miroa is more caring towards people, Gotoh picked him as the successor and gave him the Aura spell. Out of jealousy, Gharnef stole the Imhullu spell and it twisted his soul. Ever since then, Gotoh keeps watching over his actions and hopes someone would stop him. That someone happens to be Marth, descendant of the hero Anri. Gotoh then assists Marth in his quest, giving him advices from time to time. He joins very late in the game, Fire Emblem: Ankoku Ryū to Hikari no Tsurugi, although he was changed to a major NPC in the remake and sequel Fire Emblem: Monshō no Nazo.

Note, despite being born a pure Manakete he can not transform. It is mentioned in Fire Emblem Mono No Nazo, that all divine dragons lose the ability to transform. This is presumably why he is a Sage class rather than a Manakete, although, though this is conjecture.

The Archetype
Gotoh started an archetype of characters who join very late in the game at nearly maxed level with at least competent stats, so that players who deploy weak armies in the final chapters can stand a chance.
