We need tall imposing villain figures. Besides, lost a jaw. That was original, instead of hand or arm or leg or lung.
He's badass. Like Vader--tho vader is probably angrier.
Yeah, vader had the constant agony of the burns from 23 until death. To be calm and still able to fight almost as badass as he ever did...is impressive.
Look it up--I remember reading somewhere that, yes, Malak was somewhat inspired by vader--they got orders from lucasarts that the main villain had to have a familiar feel.
He'd be more of a wannabe if he were dressed in black.
Nihilus is more Vader esque.
