Largest boss ever? Look at Kronos from gow3
Though size isn't everything when it comes to bosses (unless you are a slut).
As for scalebound, it looked ok at best. The boss just didnt look fun or challenging, his attacks looked lacking and stupid, and the way the boss progressed just seemed... eh... mediocre..
And for fucks sake, the protagonists is the most annoying person in the world
