Surprise!
Mimics are very dangerous, as many Gungeoneers foolishly drop their guard around treasure chests. Some experts argue that the Mimic is the true master of any dungeon, as no monster is more at home than the Mimic.

This article is about mimics that pretend to be chests.     For mimics that pretend to be boss reward pedestals, see Pedestal Mimic.     For mimics that pretend to be walls, see Wall Mimic.     For mimics that pretend to be guns, see Mimic Gun.

Mimics are a family of enemies in Enter the Gungeon that disguise themselves as scenery, items or containers to catch players unaware.

Spawn Conditions

Mimics are not pre-placed in any room layouts, instead they have a 2.25% chance to replace any applicable chest, with this chance increasing by 2.1% for every level of Curse the player has. A mimic pretending to be a chest can usually be spotted by the lid of the chest slowly raising and lowering as the mimic breathes, however more powerful mimics tend to be better at hiding these tells.

Unlike other curse-based mechanics, there is no cap on how much curse can increase mimic spawns. At 47 Curse, all applicable chests will become mimics. In co-op mode, both players curse stat is added together to determine mimic spawn chances.

Mimics can only be encountered after at least 2 hours of total playtime on the current save file.

• Ring of Mimic Friendship prevents chests mimics from appearing.
• Mimic Tooth Necklace forces all chests (with the exception of Rat Chests and chests that have no valid mimic type) to be unlocked mimics.
  • Possible Bug Mimic Tooth Necklace actually has an inverse effect on Rat Chests, forcing them not to be mimics.
• If the player has Ring of Mimic Friendship and Mimic Tooth Necklace, all valid chests will be unlocked but will not be mimics.

Behaviour

Unlike regular enemies, mimics will wait until the player attempts to open them, or until they are shot, at which point they will spring their trap and suddenly strike. When killed, Chest mimics will drop the item or gun inside them. Unlike other Mimic types, they do not give additional item loot- however they still allow the player to conserve resources by 'opening' them using firepower rather than a Key.

• Attempting to use a Key to open a Mimic still consumes the key, rendering it a waste of resources.
• Picking a mimics lock with Trusty Lockpicks does not awaken the mimic, regardless of whether the lockpick was successful. Mimics with broken locks cannot be interacted with, but can still be shot to awaken them. Broken-locked mimics behave normally, and will still drop items.

Brown, Blue and Green Mimics

The behaviour of a Blue Mimic. Aside from HP values, Brown and Green Mimics also behave this way.

Replacing , , and chests respectively, Brown, Blue, and Green mimics make up the majority of chest mimics a player will encounter.

On revealing themselves, these mimics will open by shooting a single jammed bullet in the player's direction, which bursts into a radial ring of 8 evenly spaced bullets in all directions after traveling a set distance.

Pulling out guns, the mimic will then begin an erratic style of attack, quickly running to random points in the room and shooting rapidly at their target. Because mimics don't chase the player in the linear fashion of other enemies, they can be particularly hard to hit.

• Of the three, Brown Chest Mimics are the worst at concealing themselves, and always appear without locks. While brown chests spawned on room clear may also be unlocked, any pre-unlocked brown chest in a chest room is always a poorly concealed mimic.

Red and Black Mimics

The behaviour of a Red Mimic. Aside from HP values, Black Mimics also behave this way.

Replacing and chests, Red and Black mimics are pose a much greater threat than their smaller counterparts. Once awakened, they will take a moment to prepare before beginning an onslaught of relentless room-filling attacks.

Rather than holding guns in their hands, these mimics will open their mouths to reveal twin miniguns, and will flood the room with waves of bullet rings, with four waves per attack. During the first to third waves, they fire three rings of bullets in quick succession, and during the fourth wave, they only shoot out one ring. While firing these rings of bullets, they will also shoot straight lines of bullets in random directions, overlapping the rings.

• Red Chest Mimics are relatively easy to spot, as they never fully resemble an innocuous red chest. The most notable example of this is the gap between the lid and base of the chest, which always appears suspiciously ajar on Red Chest Mimics. Unlocked red chest mimics still appear visually to have a lock, although this is a less useful indicator, as red chests are rarely unlocked.

Rat Mimics

The most powerful form of chest mimic, Rat Mimics only appear in the Reward Room after the Resourceful Rat boss fight- replacing the large Rat Chests found there. Once awakened, these large enemies will reveal twin box rockets (resembling the Com4nd0) and proceed to run around the room, regularly pausing to launch two arcing clusters of triangle shaped bullets towards the player.

While not a property of the Rat Mimic itself, if there are multiple Rat Chest mimics in the room, the fight with one will almost certainly awaken all the others.

• Rat Mimics were added in the Advanced Gungeons & Draguns Update.

Other Appearances

• Baby Good Mimic is a small, friendly mimic companion.
• The Union Mimic is a Green Chest Mimic with googly eyes who appears only in the Reward Room after the Resourceful Rat boss fight if the player has Mimic Tooth Necklace. He is not hostile, and is there to apologise to the player for the inability of the Gungeon Mimic Union to replace the Rat Chests with Rat Chest Mimics.
• A Brown Chest Mimic makes a brief appearance in the animated launch trailer for Enter the Gungeon, where it ambushes the Hunter.
• A Brown Chest Mimic appears in key art for the Advanced Gungeons & Draguns Update illustrated by Max Grecke, where it appears to be devouring a Bullet Kin.
• A mimic with red eyes appears in early key art for Enter the Gungeon, illustrated by Maximo Lorenzo.

Unused and Cut Content

• The unused Bunker boss also has an unused mimic form- the Bunker Mimic.
• While all chest mimic types share a single Ammonomicon entry, unused Ammonomicon portraits for the different base types of chest mimic exist unused in the assets of Enter the Gungeon.

Notes

• Brown, Blue, and Green chest mimics wield twin Magnums.
• Homing bullets, full room damage effects, and companions will ignore mimics that have not yet been revealed.
• Shooting a mimic that is still hiding to awaken it will not deal any actual damage to the mimic.
• The Dog will run up to mimic chests and bark at them, trying to alert the player to the deception.
• Mimics can spawn as fused chests. Fused mimics will explode after a delay like regular chests, and will not drop an item. Awakening a fuse mimic disconnects the fuse. Fused mimics do not behave any differently once awakened.
• Awakening a mimic by shooting it first instead of interacting with it unlocks the Not Just A Box Achievement and the Book of Chest Anatomy.
• The sixth Infuriating Note is obtained from killing a chest mimic.
• Pedestal Mimics can only spawn once a regular mimic has been encountered at least once.
• Wall Mimics can only spawn once regular mimics or pedestal mimics have been encountered at least three times.
• Mimics are immune to transmogrification effects like Magic Bullets, Snakemaker, or Devolver Rounds.
• Killing a Mimic in Rainbow Mode will not drop an item. Instead, Mimics will leave behind a note from Bowler calling mimics gross.
• One of Frifle and the Grey Mausers hunting quests is a contract to kill three mimics. All types of mimic, including wall, pedestal, and door mimics count towards this quest. Completing this quest unlocks the Mimic Tooth Necklace.
• NPCs, including Bello, do not react to mimics in any way.
• If a Mimic is killed by falling into a pit, the items it drops will not be lost and will appear on the edge of the pit.
• In the rare event that a chest is unable to determine its contents, it will automatically transform into a Mimic as a fallback. If this happens, the message Emergency Mimic swap... what's going to happen to the loot now? is printed to the Unity error log.
• Mimics are a classic enemy from Dungeons and Dragons that have appeared in innumerable games and other media since their inclusion in the 1977 Monster Manual.
  • Dodge Roll lead designer Dave Crooks is a self professed lover of mimics, and is likely the driving force behind the wide variety of mimics in Enter the Gungeon.
• Dave Crooks has joked on Reddit about implementing 'Double jammed purple friendship glitch mimics' to Enter the Gungeon.

Bugs

• Bug There is a very small chance that Brown, Blue, and Green chest mimics will fail to pull out their guns when awakening, preventing them from shooting at the player.
• Fixed Bug Prior to version V1.0.8 killing a mimic had a chance to spawn room clear rewards.
• Fixed Bug Prior to version V1.0.10 killing a mimic by pushing it into a pit could cause it to drop double loot.
• Fixed Bug Prior to version V1.0.9 Mimics could not leave the Chest room they spawned in.

Unintentional Mimic Types

Unintentional Mimics are mimics that have spawned from chest types that they should not be able to.

Rainbow Chest Mimic

A Red Rainbow Chest Mimic

Rainbow Chest Mimics are Rainbow Chests that, by one means or another, have become mimics. Prior to version v1.0.10, this could happen naturally in a run- although it was extremely rare. Rainbow Chest Mimics were accidentally added back into the game with version v1.1.0, the Supply Drop Update. The Chest Teleporter active item added in this update allows the player to send a chest to the next chamber. Chests teleported to the next chamber have a chance to become mimics, including Rainbow Chests.

• There is no set mimic enemy definition for a Rainbow Chest. As such, "Rainbow Chest Mimics" look and behave like the type of chest that the Rainbow chest was before becoming Rainbow. For example, a blue chest that is upgraded to a Rainbow Chest, and then becomes a mimic, will look and behave like a Blue Chest Mimic when activated.
• Regardless of the mimic enemy type they use, Rainbow Chest Mimics will drop 8 items and guns when killed.
• While in concealed form, Rainbow Chest mimics adopt the appearance of the chest they were before being upgraded to Rainbow, with all their mimic tells. Additionally, each type of chest (with the exception of Green Chests), retain the rainbow visual effect on some part of their sprite.
  • Brown and Blue Rainbow Chest Mimics have rainbow trims.
  • Black Rainbow Chest Mimics have rainbow bones.
  • Red Rainbow Chest Mimics have rainbow bodies, very closely resembling a normal Rainbow Chest. These Rainbow Chest Mimics most closely match what a person might expect a Rainbow Chest Mimic to look like.
• Rainbow Chest Mimics lose the rainbow visual effect when awoken.

Glitched Chest Mimic

Glitched Chest Mimics are Glitched Chests that, by one means or another, have become mimics. In older versions of Enter the Gungeon this could happen if the player had Mimic Tooth Necklace. This was eventually patched out of the game, but was accidentally added back with version v1.1.0, the Supply Drop Update. The Chest Teleporter active item added in this update allows the player to send a chest to the next chamber. Chests teleported to the next chamber have a chance to become mimics, including Glitched Chests.

• There is no set mimic enemy definition for a Glitched Chest. As such, "Glitched Chest Mimics" look and behave like the type of chest that the Glitched chest was before becoming glitched.
• Interacting with a Glitched Chest Mimic does not awaken it like a normal mimic. Instead, the player will be taken to the Glitched Beholsters fight as if the Mimic was a normal Glitched Chest.
• Shooting a Glitched Chest Mimic will cause it to awaken, and attack the player like a normal mimic. Killing a Glitched Chest Mimic will not take the player to the Glitched Beholsters fight, but will instead drop an item or gun corresponding to the glitched chests quality.
• Glitched Chest Mimics lose the glitched visual effect when awoken.
• Dodge Roll lead designer Dave Crooks has joked on Reddit about adding Glitched Chest Mimics to Enter the Gungeon in an official form, however this never came to fruition.

Truth Chest Mimic

Prior to version v1.0.10, Brother Albern's Truth Chest could be a mimic. The form this mimic took is currently unknown.
