Unil

Unil is a playable character in Fire Emblem:Shadow Dragon. He has no portrait and can only be obtained if you have less then 14 units at the end of chapter 3. He is selected at random between other non-portrait characters. If you have at least 2 or more less then 14, you may get Unil and other characters. They are not as strong as other characters. Unil is either a Dark Mage or a Hunter, but either way you can reclass him.
