Which monster, of your own creation or from some source, was the most gonzo or weird you've ever used in a fantasy RPG campaign?

Much as I may malign the game... 4e D&D Gamma World had the funny idea of a character composed of a group colony of kittens that formed a humanoid shape.

Other oddities...

Cyborg mushroom men that evolved from an early play through of How to Host a Dungeon.

Someones session of Mekton Zeta which was essentially based on the animated move Cars, and later Planes...

This time last year my players faced a giant Turducken of Terror...a three-headed gravy-breathing giant turkey which, when slain, released the slightly smaller two-headed duck.  Upon killing the duck, the players took the (normal-sized) indigo hen inside as a potential familiar.

I think that probably counts as crazy.

Well, there was the nameless thing in the temple of the love god.  It was a gesalt of dozens of people having sex, a roving orgy shoggoth kind of thing.  Of course the PCs were wondering about the butcher tables and torture chambers in the lower levels.  Nobody ever said the god of love was Good.

I ran a Call of Cthulhu: Delta Green game a while back...

Investigation into a bunch of mysterious deaths, bodies with a few holes in them and drained. A previous investigator had been killed in his bed, also holes, but not drained. Hrm.

Investigators holed up in an apartment, contemplating their next move. There's a noise in the bathroom... they carefully peer in, guns drawn. Something broke in through the window, a noise... but nothing visible.

One casts Voorish Sign, which reveals the unseen... and the small writhing shape, pink and dripping, appears near the ceiling. A lot of screaming and shooting.


They then determine that all the female victims had had an abortion from a particular clinic... a particular doctor. At least some of the male victims had been boyfriends of the female victims.

Yeah. The doctor was a cultist, infusing aborted fetuses with strange puissance. But for them to reach full size and power, they needed to find their parents, and caress them with long ropy entrails, with sharp teeth...

They were the aborritions.

With ease I can say one of the most hated things I ever threw at a party in a D&D 3.0 campaign was a pack of dire rats. Granted, I used the listed advancement rules to Huge Size which was a size they were never meant to be. Apparently, at something like 12 HD they became murder machines. This made my players very sad. :mad:

That likely wasn't the most gonzo of creations but it was an enlightening look at how monster rules worked.

For more gonzo, it requires a bit of set up. The party was in a blighted forest with veins of crossover slime killing all the plant life, mostly rotting it form the inside. After escaping a tumulus they had been lured into they found the world had changed. The rotting trees and dead grass had been replaced by a vivid and lush lollipop forest with singing gumdrop bushes. The dancing gumdrops sang, eat me! Eventually, someone gave into this compulsion and dined on a diminutive grey ooze. There may have also been a host of handsome princes on unicorns wooing party members but that's what happens when a Hag Coven gets together to have some fun.  

In Fractured Kingdom one of the creatures I've had the most fun with is the Broken Dream, which is an incomplete dream ripped from someone's mind and given shape. Since their appearance is really determined by the dreamer I've had a lot of fun asking players about character dreams and later subverting them, this has included a small child with what was clearly a small apple stuck in their throat to a pair of legs with no upper body beyond the waist.

I once asked my d20 Star Wars Players to go crazy on creature creation and one of the little shits made a Force-Using Voorpak which had multiple attacks and Toughness and Improved Initiative and NPC levels. No problem, I thought, it is the size of a rat.

They look like this:







Now this particular Voorpak was kept as a pet by the Player and initially I thought nothing of it. Then during combat, the Player threw it at a bad guy and the damn thing won initiative, hit with every attack, critted with half of those, and basically left a mist of blood where the target had been standing.

King Diamond, complete with backing band. Palladium Fantasy.

He was a demon lord who every 100 years would appear and desolate the surrounding area with the power of his terrible rock. His only weaknesses were electric attacks and the sound of acoustic instruments.

To better simulate and just to make everyone as uncomfortable as possible, I blasted an album during the battle so loud that everyone had to yell their actions.

A human head with spider-like bone legs and wings. I think I lifted it off from Doom 3.

Sadly.. I'd have to say "Yeti Lee". A yeti who's mesmerizing howl took the former of "fly by night" from Rush. Then he would pummel the victims with up rooted pine trees.

I wish I could say this was in the 70s but I'm not that old. It was a couple of years ago and evolved from a player that was having work issue with his telecommute kanucks.

An Eagle-crab.  Body of a crab, head of an eagle, with the lobster claws and scorpions tail.  My players christened it, the "cragorpion."  Also had these flying bat things that scooped up blood in pelican-like mouth flaps.  The players called those "balicanths" (not sure why).

In this one FASA Star Trek Klingon game, the GM had us on a planet where one of the mutated species was vampire sheep.

In an old supers campaign, I had an evil robot who made clone minions who were cowboys, each shooting nitroglycerin shells. They were called "cowbombs", and said western tropes with no bearing on the situation at hand. They all dressed mostly like rodeo cowboys too.

To this day, I don't know where I came up with them, or why I kept using them. My players hated them!

In one of my Cthulhu campaigns the players, investigating a Cult that was sacrifing babies, ended up facing a creature that was basically a living pillar of liquid flesh that constantly bubbled; each of the bubbles formed into the face of a wailing baby. But it didnt get really weird until the players defeated it by shoving a medallion into it. The medallion had been used as a key to open a portal to the Dreamlands.

The first time they'd entered the Dreamlands they encountered a  great river of blood. Subsequently to defeating this creature, it had infested the Dreamlands and now the river was a river of boiling flesh and bubbling out of it were wailing baby heads that ballooned to the size of pumpkins and flew out devouring anything living nearby. When struck, they exploded in a a mass of pus.

The King of this particular realm of the Dreamlands was Pumpkinhead, pretty much an evil version of Jack Pumpkinhead from Return to Oz. The infection of this creature spread to him and his head became a globe of liquid flesh with the same properties as the river, while his lower body became a centipedal mass of child arms whose fingers had been reduced to sinew and shards of bone.

The Horror Eater of Innocents I made for The Prelude to Evil for Gencon would be mine.

A classically mopped top baby's head on top of a fat baby body with a massive toothy maw that opened to an umbilical chord tongue with arms and legs replaced by pink tentacles. Making for a mixture of huge human baby and monster. The Horror's maw in the middle of the body would talk gratingly and then be immediately mimicked with baby babble or child speak by the baby's head. Like the maw, "I'll kill you!" and baby's head, "Goo goo ga ga."

Both tentacle arms entangled two player characters and another one was being strangled by the umbilical chord maw. The maw laughed and then the baby head on top, "So many playmates makes me happy!"

It was a player favorite the two times I ran the game.
