“Yeah, I'm just fine. I want to join Sir Seliph's liberation army, father. Thracia is not like it used to be... I want to fight for the people!”
—Corpul in Genealogy of the Holy War.
Corpul (コープル, Kōpuru, translated Corple in some of the fan translations) is a character from Fire Emblem: Genealogy of the Holy War and Fire Emblem: Thracia 776. He is Sylvia's son and Leen's younger brother. In the context of the game's events, he was adopted by Hannibal after being abandoned by his mother in an unknown orphanage, and is later used as a hostage by Travant as a punitive means to force his adoptive father into battle.
In Chapter 9, Corpul gets the chance to meet his sister Leen for the first time, but neither of them ever learns that they are siblings, even after the defeat of the Grannvale Empire. His substitute character is Sharlow.
He makes a few cameos in Fire Emblem: Thracia 776, in which he can be rescued in Chapter 3 from Manster Castle. He will later be seen at the end of Chapter 7, whereby Leif may receive a Warp Staff from him.
Corpul, sadly enough, comes extremely under-leveled and rather late in the game. This very fact thus causes many players to bench him. His replacement Sharlow comes with the Elite skill and can obtain the Berserk Staff, making him somewhat easier to use.
Nevertheless, Corpul should not be neglected, as he will be able to fulfill the Est archetype qualities fairly well, should his mother be paired up with a competent father. The preferred options are Claud (who passes major Blaggi blood *and* the Valkyrie Staff on to him), and Alec (who gives him Awareness and Pursuit). To counter his problem with level the player can give Corpul the Reserve Staff and make him use it everytime someone is injured this will give him a large amount of experience points everytime and will let him gain levels often.
