Рейвен

Raven is a General in the Amestrian Military and one of the elite members of Central High Command in the capital. General Raven makes his first appearance in Chapter 50 of the manga, while Colonel Roy Mustang contemplates how to go about using the information about King Bradley's true identity as a Homunculus.

At first it appears to Mustang that Raven can be trusted (the General's jovial nature and complimentary speech putting the nervous Colonel at ease) but when Mustang tests the waters by mentioning a rumor about the Führer being a Homunculus, Raven leads Roy into the Central Command room and repeats the rumor for all (including Bradley himself) to hear, revealing that ALL of Central Command is already entrenched in the malevolent machinations taking place in Amestris at Father's behest.
