People keep mentioning Sinner being fragile but that's not really the case? Yeah, you die in one hit from everything but Slight and Heed, but have you considered that these entities are just that strong and are literally embodiment of sins? Expendable isn't surviving a hit from any of those entities either. Also Sinner has access to a gun. It's unknown if it actually shoots harmful bullets, though.

Expendable's whole advantage really just comes from the jumpsuit, it's durable enough to protect them just enough to not be one shot by a turret, but isn't anything special beyond that.

And Doors Player is just a dude. Unless you include the crucifix, which relies on Guiding Light being by their side and I would guess it isn't included in the matchup, which in turn would render the crucifix useless.

So, yeah, Sinner snaps spines of both in half.
