Jagen (known in Japan as Jeigan) is a character from Fire Emblem: Shadow Dragon and Fire Emblem: Monshou no Nazo. He serves as Marth's bodyguard and one of those that Marth turns for advice. He is an invaluable unit at the start of the game but he has low growth rates and lacks potential, thus crippling usefulness in later parts of the game, and the excuse is advanced age. He jump started an archetype of units who are introduced at the beginning of the game and have low potential and hog up experience at the start of the game, hindering stat growths of lesser trained units. Such units appeal to newcomers of the Fire Emblem fanbase, but they are generally frowned upon by knowledgeable Fire Emblem fans.
