Funf is one of the 12 Dark Warlords. It should be noted that Funf is male in Fire Emblem 4, but female in Fire Emblem 5.

In Fire Emblem: Seisen no Keifu, little is said about the Dark Warlords, but they are all fought in the Final Chapter near Barhara, and eventually defeated, including Funf.

In Fire Emblem: Thracia 776, Funf is fought in the Final Chapter. The character that becomes Funf is Evayl if Evayl isn't saved from Veld's Stone spell.

Seisen no Keifu
Funf should be easy to defeat. Being a Sniper, just surround him and kill him, but he should go down with 1 or 2 direct rounds of battle, so that probably isn't even necessary.

Thracia 776
Funf may not be able to directly attack, but don't let that fool you. Her dodging abilities are extreme, and Prayer only make her all the more deadly. First off, make sure that Eins is dead so his leadership stars don't make her harder than she has to be. Second, if Sety or Galzus is close to her, you are in luck; either of them will easily be able to destroy her assuming her prayer skill doesn't mess you up. However, if Mareeta is close by her, she can destroy her easily with Mareeta's Sword due to the Awareness the sword gives her which nullifies her prayer skill, but it is preferred, if you can, to have Mareeta take care of Elf.
