If you’ve ever played an RPG before, It’s incredibly likely you’ve run into a Mimic, whether you knew it or not.
Origins of Mimicry
The Mimic is an absolute classic D&D monster, and has been around since the beginning of Advanced Dungeons and Dragons way back in the 1977 Monster Manual. It was a bane of players then, and it’s a bane of players now. The Mimic is a mysterious purple critter with glue-secreting skin that allows it to stick to anyone who decides to touch it. This, coupled with its ability to shapechange into any object it likes. Doors, pillars, treasure chests, trash cans, bookshelves, beds, coffins, and even unlit chandeliers can be Mimics!
The trademark Mimic transformation is that of a treasure chest. This means that greedy adventurers and thieves can be caught and eaten fairly easily, as it’s impossible to tell if a treasure chest is a Mimic ahead of time just by looking at it. But what if the Mimic is just carrying around her babies inside her? The sword, the helmet, and the book are all Mimics! Mimics also cannot digest anything that isn’t organic, so a Mimic could eat a hero and have their stuff left over in its chest form as enticing bait for the next group of fools.
A Mimic is indistinguishable from other normal items while it is completely still. This leads its prey to it. This is a tactic often used by carnivorous fly traps in our world. Look enticing; sit still; eat whatever touches you.
Picture a torch-lit room with beautiful wood furniture, velvet drapes over the mantle, and a golden chandelier. In the middle of the room is a chest. While it looks solid wood and metal, the chest that lies before you is enticingly placed with a slight opening in the lid showing the gold inside it. You grab your ten-foot pole, because you’ve run into this sort of thing before, and lightly prod the box. You feel a heavy thunk on the other end, and you and the rogue exchange a confused look. It certainly sounds real! You prod the carpet underneath, you prod the chairs nearby, and you prod all the furniture in the room. Your caution turns to glee, and you rush forward to grab what lies inside.
In your urgency and greed, you completely forgot about the chandelier. It wasn’t at the forefront of your mind, but why would a torch-lit room need a chandelier?
Suddenly you hear the Rogue scream and you turn around as the chandelier drops on her. She’s trying to stab it, but her arms and legs and hair are all caught up in the gunky adhesive skin of the Mimic. You pull an axe and chop downwards, but it just sticks deep into the Mimic’s flesh with a schluck noise and stays there. You go to kick it but your leg sinks into its flesh too. The feeling is not unlike that of bread dough, but stickier.
The Mimic smashes you across the face with its long chain, and you blink back the bright colors and spots in your vision. The awful acidic smell is burning your nostrils and you find yourself about to pass out, until the Rogue slips out from under the Mimic and hacks it away from you.
Your stomach flips and you turn as the chandelier quickly melts into a purplish creature with beady amber-colored eyes and a large toothy maw, that is now dead on the floor and oozing violet blood. You and the Rogue exchange a look and begin to prod every single object in the room again with your 10ft pole.
The Mimic is far less extravagant and dramatic than any other monster I’ve discussed on here, but it is chock full of set-ups and interesting battles. Having your purse try to bite your hand off or the local fountain eat all the children who hop in for a quick dip can lead
s to some seriously fun and bizarre plot-hooks that all DMs will appreciate.
