What was your favorite monster (from MM, FF, or MM2)

[Prince of Happiness]

When I was a weeeeee one, the pictures of the sea hag and the morkoth wedged itself in my little mind.

Ultimately though, gnolls are still my faves, though I'm still itching to spring a thoul on people.

FF: Shadow Demon.

No reason really

LOL.

As to the original question, I couldn't possibly decide. Either the Githianki or a Demon Prince, most likely.

[Thomas Percy]

Dragon.

 

[Heathansson]

Githyanki. The githyanki on the cover of the original 1e. Fiend Folio just blew me away as a kid.
I also used to play Rifts, and this one character always astral projected with nigh impunity. So I imported some githyanki who were "curious" about him. He cut back on the astral jauntiness.

 

[dcas]

Yellow Musk Creeper & Yellow Musk Zombie (FF)

 

[Shadowslayer]

Heh, my unsuspecting butt once got kicked by a Guardian Familiar. That was pretty memorable...."nice kitty...c'mere kitty...hop down off the chest kitty"

That was in the FF.

Honorable mention to the Piercer.

 

[BullMarkOne]

Mindflayer. Just the description/image is cool -- although I think that may be coloured by a Fighting Fantasy bestiary with a similar creature. (Anyone know where I can get my hands on one? I gave mine away years ago.)

Ditto on the mind flayer.. they were in the first issue of dragon magazine I ever bought (can't remember the number.. and lost it moving around a few years ago ) Not to mention all the added mindflayer coolness in spelljammer.

 

[BroccoliRage]

The Displacer Beast. What a great monster.

I've always been partial to Orcs, though.

 

[AFGNCAAP]

Xvarts.

Those evil Smurfs were just a nice twist to throw at parties instead of the typical goblinoids, kobolds, or orcs.

 

[Aus_Snow]

Back in the day (OK, not that long ago ) I particularly liked Charon and Abraxus. Actually, they still look kind of cool.

These days, probably the Penanggalan. . . is that the right spelling? Anyway, probably them.
