Perceval is a playable character in Fire Emblem: The Binding Blade, and the Knight General of Etruria. He is forced to fight for Bern when Etrurian deserters capture King Mordred and force him to switch alliances. Despite his actions, he remains extremely loyal to Prince Mildain and King Mordred of Etruria. Upon seeing Elffin, he is shocked to discover that Prince Mildain is alive and well and chooses to abandon the corrupt leaders of the Bern military, joining the Lycian Alliance for the good of Etruria. He can also be recruited with Larum, since she has proof that Prince Mildain is alive.
