Van Voigt in "The Voyage of the Space Beagle", which by itself, is a fascination document of mid-century sci-fi... But completely unrelated to "Forbidden Planet". - So, which way do you want to go?
I know that was proposed somewhere but I don't think that is correct. The Id monster seems to have been adapted by Gygax as the invisible stalker (I imagine).
Anyway if you read the descriptions in the FFC, it seems to compare well with Svenson's Yth'yl from Tonisborg. (also from an old book).
Here are the stats (OD&D) I've come up with - please feel free to criticize/comment:
YTH'YL
(Svenson Tonisborg, FFC ID monster)
% in Lair: 100%
Numbers: 1
Move: 18”
Alignment: neutral
Dexterity 18
Armor Class: 2
Hit Dice: 20
Attacks: 1
Damage: 3d6 + special
Treasure Type: A
The Ylth'yl is a shimmering creature of pure energy. sometimes summoned as a guardian in the manner of an invisible stalker. The touch of the Ylth'yl causes immediate unconsciousness if a Type III (paralysis) saving throw is failed. When the Ylth'yl encounters a party, there is a minimum 1/6 chance on any successful attack that it will open it's mouth incredibly wide, engulf and swallow the victim in one swift move. That person will later awaken completely naked in a predetermined place. The Ylth'yl apparently digests the possessions.
