I've been playing through Blue Lions in Fire Emblem and I do really like some of the war time combat quotes in the game.
"Only thorns left on this rose."
"I disposed of doubt long ago."
"Only thorns left on this rose." I think is my favorite combat quote I can remember, but I haven't played too many games with combat quotes other than Fire Emblem recently. What are the best lines a character says after engaging in combat?
