Keter

I love your Object Class banescales! Tear and Skeletal are super aesthetic for SCP (and I think it's really cool how you found black-range colors that had the right matching accents for tear so that it looks like they all have the same primary), but I particularly love the green-orange-red progression as warning lights for just how screwed you are when there's a containment breach. And then Keter gets the more aggressive pose to rub it in.

(Poor Safe is just doing harmless things like turning into a bird every six hours or generating sparkly lights whenever he moves while the other two throw hands and tear up the fabric of the universe, I think he needs a hug)
