|Alternative name:||Steel Beasts|
|Battle Cry:||big death, Big Death, BIG DEATH!|
The Legio Destructor ("Steel Beasts") is probably the largest Legion of the Collegia Titanica, comprising over a hundred Titans of all classes. This is not surprising since Accatran, the Forge World it defends, lies only a hundred light years from the Eye of Terror and on the edge of the Ork empires of Charadon and the Wheel of Fire. Led by their eccentric Grand Master Thaedius Wilson, Legio Destructor have fought off numerous Waaagh!s and eruptions of Chaos from the Eye of Terror. It is rumored among some areas of the Adeptus Mechanicus that the constant battles against Orks have made the Legio Destructor increasingly unorthodox in its outlook and behavior, particularly in its attitude to battle and combat. The Princeps and crews of the Legio Destructor hunger for battle with an unusual exuberance. So far this thirst for battle has been viewed as a useful attribute, especially against foes other than Orks who find the Legion highly unsettling opponents. The Fabricator General himself is believed to have expressed surprise on hearing that the Titans of the Legio Destructor are now fitted with sonic amplifiers so that the Legion can reply to the Orks' howls with their own battle chant: "big death, Big Death, BIG DEATH!"[Needs Citation]
