The forgotten one in Lament of Innocence was this gnarly gore monster; here he is uh a big generic statute armor guy. Gabriel is a vampire now but still plays the exact same. You fight the same boss multiple times in a row broken up by okay platforming. For the majority of its fights the boss can only be damaged using aerials in a game with no air dodge, an air block, nor a way to reliably cancel aerials (you can double jump to cancel aerial combos but after that you are prone to be hit by the bosses quick follow ups). Long, tedious, and there is no reason a key part of the story should be pawned off as DLC.
