Well technically Powered Armour covers 40K's Power Armour, Terminator Armour, even Dreadnoughts and Tau Battle Suits. That is protective covering for the body in combat, or armoured fighting vehicles, that are equipped with mechanical or electrical power. But you seemed to be using the term Powered Armour to represent something in 40K that is less than Power Armour. Yet in 40K there are a lot of different types of power armour including that which Sororitas wears. Plus the term Power Armour is applied to a suit of armour that only has the arms and chest powered, the Mk I Thunder Armour. Unless of course, you were referring to the strength enhancing properties that power armour are supposed to have.
Just accept it, guys - Alpha Legion are the best, Alpharius is the best - damn, do you know of ANY other primarch who could subjugate entire systems, not just planets, to his cause without firing a single bolter round, who could win wars before they even started? Or who was considered being enough badass to be contacted by an entire cabal of ancient xeno species in an attempt to thwart Horus Heresy? And who proceeded to screw their plans afterwards? Just say it, two words: HYDRA DOMINATUS!!!!!!!!!!!!!!!!
Rogal Dorn may have been an Alpha legionnaire himself, btw, and Alpharius's death was staged One doesnt need to know of the Hydra to be one of its many heads.....
Alpharius had his disguised legionnaires in almost every legion - many of them can never know who their victories really benefited to
