Echidna is a playable character and a Hero from Fire Emblem: The Binding Blade. Echidna is the leader of the resistance force against the Etrurian government in the Western Isles. In the northeast side of Chapter 9 there are two villages. She is recruited only if a unit enters the village on the left or neither village is visited. Echidna is recruited when Larum talks to her. During the battle in Chapter 11, the Etrurian soldiers surround the house she is in and threaten to kill her if she does not surrender. In her supports, she attempts to gain recruits to help her in her plan to make a "free village", a village where people in the Western Isles who had their homes destroyed could settle after the war.
