Passive Literally Every Single Ability [Hades]
Currently, Hades’ page assumes his soul absorption - as well as every other ability he has access to - is passive. This is because of
this scene, and
this image from the art book. First half of this debunk is pretty easy; Taken at face value, this is just soul absorption, and none of Hades’ other abilities are used passively here. There is no reason to assume stuff like, say, life absorption, BFR, or underground mobility are being used passively here.
The first part is also easy, because there’s not really an indication his soul absorption is passive in the first place? Sure, it’s not made explicitly clear that Hades activated some sort of special ability here, but during the first half of the fight, he isn’t absorbing any souls. When he
tries to take Kratos’ soul, it’s not done passively, but by Hades having to really struggle to try and rip it out, a thing which we see happen again
during the war with the Titans. If this ability is passive, then all the Titans should’ve just died on the spot, and Kratos should’ve been fighting back against Hades’ attempts to rip out his soul during the entire fight, not just those initial few seconds.
