The Legio Victorum has never wavered in its devotion to the Emperor, revered him as the Machine God incarnate and as such consider him embodied in the dominating presence of each Titan. The Foe Slayers Legion crewmen, through their indoctrination to the Legion, all have one thing in common - an utter belief that Mankind has the sole right of existence in the galaxy. The fighting men of the Legion do not tolerate the alien in any shape or form. Their dedication to this goal of eradication has extinguished many races that the Adeptus Terra originally designated as harmless and has left more powerful alien races, such as the Eldar, extremely wary of the Legion's presence in any theatre of war.
