ebiflynageruyo was able to mod Demon’s Souls, and demonstrate unused content by swapping enemy models. It’s primarily a cosmetic change so we only get to see their models and some of their animations. Otherwise their stats/ AI/ placement should all be based on the enemies they’re replacing.

It gives us a much better look at how these would’ve appeared in-game:



The videos also show some odd content like a red bow, and things like unused upgrade materials added into the inventory.

I’ve created a playlist of the videos, and you can find the uploader’s channel here.
