What monsters are you hoping are in Mordenkainen's Tome of Foes?

[Elderbrain]

Please list ones you want that have not yet been confirmed. For instance, I want Dabus, Bariaur, Baerenoloth, Yagnoloth, Maeraenoloth, Asuras, Tharizdun, Queen of Chaos, Miska the Wolf Spider, Spyder-fiends, Vaati,
Obox-Ob, Pazuzu, Dagon, Koshtichie, Pale Night, Anthraxus, Midianclarus (the Oinoloth), The General of Gehenna, Archons, Planescape Eladrin, and the Gehreleth (demodands).

 

[Kobold Avenger]

I want Guardinals and Rilmani in.

Not to mention Kaorti, Ethergaunts and Psurlons (to add an extra dimension to conflict involving the Githyanki).

 

[Azzy]

Yeah, I don't see them statting up Tharizdun—being a got that require a coalition of other gods to lock away. I also doubt that we'll see Queen of Chaos or Miska the Wolf Spider.

But, to add to your list—the Slaad lords Ssendam, Ygorl, Wartle (and maybe the later additions Chourst, Rennbuu, and Bazim-Gorag). Primus, and the rest of the Modrons that weren't in the MM.

 

[Tales and Chronicles]

IIRC, 4e had a cool Astral Kraken that could be cool to see updated.

Primus? Maybe Mimirs? High level Fey lords/ladies? There's so many things but nothing particular comes to mind.

Gargantuan Flumph Swarm!

EDIT: Genie Lords could also be great, or anything elemental really. Outside PotA, I've not seen many elemental creatures.

Much of what I wanted to see in once the release was announced has since been confirmed to be in. Of what hasn't been announced, I would really like to see the archons, guardinals, and hierarch modrons appear...

Remember the Inevitables from 3E? That was a cool concept that I'd like to see continued. 4E was calling them "maruts" or something, but it just wasn't the same.

 

[MechaTarrasque]

More or less in order: Guardianals, OG Slaad lords (and golden slaadi), some templates* (celestial, clockwork, aberrant), phoenix, archfey, (probably the most unlikely of my requests to be fulfilled) a couple of higher end celestials, Lolth, piscoloths, Gehreleths, hydroloths, 4e style angels (if they want, they can make them into archons), retrievers, one higher end yugoloth, and CR 8 and 9 elemental myrmidons (8 as casters and 9 as warlords).

* it sounds like there will be a bunch of cult features that amount to templates for demons and devils.

 

[gyor]

Phoenix.

From my perspective there are a lot of misconceptions about the big T. When I did my research for a 5e update of Tharizdun I only found one official stat block and he as a low level god (low end intermediate if I remember correctly). Just because a god is on a course to bring out the destruction of the universe doesn't mean they are, themselves, particularly powerful on an individual combat basis. Though his only official stats had him similar in power to Tiamat (who has been stated in every edition I believe), I too doubt he will be stated.

The Marut was one type of Inevitable in 3.x. And according to this thread they are already confirmed to be in the new book.
