History Main / ChestMonster

* ''Manga/FrierenBeyondJourneysEnd'': A RunningGag throughout the series is Frieren getting fooled by mimics (who look like ordinary treasure chests, but can be magically scanned to reveal their true nature) and having to be saved from being eaten by them.

* ''Manga/InterspeciesReviewers'': Mimic succu-girls are a variation of this adapted to using more than one kind of container, as seen in the Adult Toybox with a treasure chest, a gift box, a wardrobe, and the receptionist uses a pot.

* ''Webcomic/KillSixBillionDemons'': One of the many traps in Mammon’s nigh-impenetrable vault are entire rooms filled with ''DND''-style treasure chest mimics (though some take different forms), designed explicitly to lure in any greedy adventurers looking for treasure. They can take on many shapes and sizes, including coins. Unfortunately for them, they're kind of stupid; if you leave a room full of mimics alone, they'll eventually copy each other haphazardly until the whole room is filled with copies of one single object.

* ''Webcomic/RustyAndCo'' follows the adventures of a party of iconic ''D&D'' monsters, one of whom is a Mimic whom default form is a chest. [[spoiler:And his real name is "Boxford".]]

* Mimics in ''WebVideo/VitaCarnis'' are a species of skinless {{Humanoid Abomination}}s grown from MeatMoss with AbnormalLimbRotationRange, which they use to ambush humans by hiding inside furniture. To make matters worse, after consuming enough human flesh they can pull off a TheyLookLikeUsNow (with ''[[UncannyValley very limited]]'' success).

** The series has this during and episode in the Thriller Bark arc where Nami opens a chest and a surprise zombie pops out.

* In ''Series/KishiryuSentaiRyusoulger'', the MonsterPfTheWeek is the literal trope called the Mimic Minosaur. It managed to trap most of the Ryusoulgers in its dimension. It is one of few Minosaurs that originated from an object (a chest box in its case).

* In ''Series/KishiryuSentaiRyusoulger'', A literal trope called the Mimic Minosaur trapped most of the Ryusoulgers in its dimension. It is one of few Minosaurs that originated from an object.

* The spider-tailed horned viper, which is native to Iran, uses an even more sophisticated lure; as its name implies, the end of its tail is shaped like a spider, and it completes the disguise by wiggling the tail back and forth so that it looks like a spider skittering around. Insectivorous birds coming to try and nab the "spider" will suddenly find themselves being attacked by a bird-eating snake. Interestingly, the snake only seems to feed on migratory birds, suggesting that birds native to the area have already learned to recognize the difference between it and real spiders.

Subtrope of MimicSpecies. Compare PoisonMushroom, which is a harmful ''item'' disguised as a beneficial one, and AmbushingEnemy, which is an enemy that hides in and/or disguises itself as the scenery (though this trope applies if the monsters have to be dug out of the walls first). May overlap with TreacherousCheckpoint if the monster disguises itself as a CheckPoint or SavePoint. The inverse is a FakeTrap, where something in the game is made to look dangerous or threatening, but is actually harmless. Can be seen as a form of BoobyTrap.
