A discussion arose in a mailing list I'm on that turned to the topic of
Dungeons and Dragons monsters that have the ability to turn characters
into monsters too. We've been brainstorming up as many as we could think
of offhand, but I figure this is a likely venue to find the ones we've
forgotten since the mailing list isn't really D&D-oriented.
We've been skipping the undead, since there are so many of them that
raise their victims it'd make the list way too long.
The ones we've come up with so far:
Every lycanthrope - too many to list the subtypes of.
Mind flayers - reproduce by sticking larvae into humanoids
Kaorti - humanoids that have been afflicted by the effects of the Far
Realm, they capture "normal" creatures and transform them by biting down
on them for a few hours
Meenlocks - evil little ewok things that transform their victims into
more Meenlocks by snuggling with them in their underground lairs
Vargouille - Trigger transformation in their victims by kissing them.
Would hate to see them team up with the Meenlocks.
Ophidian - poisonous bite induces slow transformation into an ophidian.
Sea Wolves - are these lycanthropes, or just something very similar to
lycanthropes?
Teratomorph - an epic monster that's like an amoeboid chunk of Limbo
rampaging through the real world, constantly "polymorphing any object"
everything near it at random.
Chaos Beasts - the Teratomorphs' little cousins, they're piles of
gibbering chaos that can turn you into one too if they hit you.
The Sarrukh of the Forgotten Realms' ancient history could change the
forms of other reptiles, but few player characters are reptiles so this
is a border case I suppose.
Barkburrs - I don't know if these guys ever made it out of 1st edition,
they're a type of forest auto-defense similar to treants that ambush
harmful interlopers and turn them into trees and giant weasels and such.
Russet Mold - turns people it kills into vegepygmys? I can't remember
this one very well, not sure.
And one that a thread participant only half remembered, I'll paste the
description here and see if it's familiar to anyone:
"There was another monster, I'm not sure if it was in D&D or if I made
it up. Years ago I was sure I had read about it in the 2nd Edition
Monstrous Manual, but I couldn't find it anywhere. It's an
anthropomorphic moose, a defender-of-nature type like treants and dryads
and nymphs. It has a cube-shaped breath weapon that turns anyone in the
area of effect (except him obviously) into a small forest creature, like
a bird or a squirrel or a bunny or something. They have some variety of
chances to resist this but it's potentially permenant."
