Iago

Iago (マクベス Makubesu lit. Macbeth in the Japanese version) is a major antagonist in Fire Emblem Fates and a non-playable character in Fire Emblem Warriors.

Personality
Iago is very cruel and manipulative, and is not afraid to use any means to attain what he wants. He also revels in the agony of others and believes his intelligence is unmatched.

However beneath this sadistic veneer, Iago hides a cowardly personality and will always pleads for his life when the tide turns against him.
