Pain (デス Desu, lit. Death) is a boss character from Fire Emblem: Radiant Dawn. Together with Agony, he leads a band of laguz bandits in the desert near the Daein border.
Just like his brother, attacking him while he is not transformed makes him a cakewalk, but when he is transformed he is a serious challenge. Some of your weaker members like Meg and Edward are most likely to die in a single blow. Letting Nolan, Aran or Sothe pull him and then finish him off with ranged attacks. Magic is most effective!
Vs. Micaiah Pain: Mwah-ha-ha! Beorc are good eats! Micaiah: Listen up! We did not intentionally intrude on your territory. Pain: Mwah-ha-ha! I'll listen…while I'm gnawing on your bones!
