Raymond Ashe

Colonel Ashe is a Cerberus operative introduced in Mass Effect: Invasion.

Mass Effect: Invasion
As Omega is attacked by Adjutants, Colonel Ashe and General Oleg Petrovsky arrive aboard the Elbrus and destroy the remaining Adjutant-controlled Cerberus transports. During the cleanup aboard the station, Ashe orders Aria T'Loak's mercenaries to finish the job and kill those who were wounded before they can transform into Adjutants themselves. Aria takes offense at Ashe disrespecting her authority so visibly and hits him with a biotic attack. Later, while Aria and Petrovsky oversee the defense of Omega from the Elbrus, Ashe is kept on the station in chains until the crisis is over. As Ashe's guards taunt him, he intimates that he's right where he needs to be. He kills the guards, then contacts the Illusive Man to inform him that he is ready for the real battle for Omega.
