Was going to no-vote, but the parallels to The Devil (aka The Beast!) are too clever for me to not +1 (like seriously "The Beast of Level 5" being basically The Devil instead of a literal beast is so clever). Anyway, here is some constructive criticism:
So, it's a good entity, but it just feels like you could have done so much more with it. This first half is excellent. You did a great job of creating a character, and establishing the "you should not trust this man-squid" thing without ever having to actually say anything. But that's just like three paragraphs. The second half though, was kind of eh. Like, you did such a good job in the first half of show-don't-telling us that he's sketchy, and I feel like you don't need a whole "DO NOT TRUST HIM" section to hammer it in. I think it would have been better if you dropped the second half, and instead either used that time to lean into the types of ideas you were exploring in the first half more, or made the second half into a more compelling story than four short paragraphs of "HE IS ACTUALLY EVIL".
That being said though, it's still a more solid article than most of the entity list, so it's a +1 from me.
