: Another thing that boggles my mind is how soulblighter
: changed so drastically from myth 1 to myth 2. He
: became more buff
That's because he cut out and secreted away his heart.
: his voice changed to sound more
: human
Bungie changed that so people could understand him. Besides, the same guy did the voices for both Balor and Soulblighter, so it would be easy for him to accidentally make Soulblighter sound too much like Balor.
: and his face went from human looking (except
: for the no mouth part) to some kind of mutant barely
: resembling a human.
Eh? He still looks like a faceless human to me. It's not just his lips he cut off, it's his whole face, from the bridge of the nose and down. Of course he's gonna look mutilated, he IS!
: I think, yes, he was the leveler.
: In the intro to myth 2, soulblighter screams for no
: reason at all when the great devoid is about to erupt.
He screamed when he failed to kill the Dwarf carrying Balor's head.
: If he could have escaped, why didnt he just do it?
: instead, he paused. He turned around, a new,
: completely different expression on his face. Anger.
I've wondered about this. It doesn't look like a completely different expression to me. It's like, he kills the Dwarf, then hears something and looks over his shoulder, turns into crows and flies away. This is the one part of your theory that I think hold up, and I wonder what it's all about...
