__TOC__
==Description==
The '''Mystery''' is a fast, weak [[Enemies|enemy]] that spawns another enemy upon its death. The enemy spawned depends on mode and wave, making the '''Mystery''' a potentially very dangerous enemy, especially if the player is unlucky and comes unprepared.

This appears in [[Hardcore Mode|Hardcore]] mode, and in some [[Sandbox Mode|Sandbox]] mode exclusive modes, these being [[Legacy Molten Mode|Legacy Molten]] mode, [[Legacy Fallen Mode|Legacy Fallen]] mode and [[Golden Mode|Golden]] mode. They also appeared in [[The Heights]] during the [[SFOTH Event]].

The '''Mystery''' can be spawned by the [[Grave Digger (Legacy)|Grave Digger]] ([[Hardcore Mode|Hardcore]] only), [[Mystery Summoner]], [[Summoner Boss]], [[Necromancer Boss]] and [[Void Reaver]]. If the [[Enemies Beta]] modifier is active, these enemies will instead spawn the [[Breaker2]].

The '''Mystery''' is replaced by the [[Breaker2]] in any map with the [[Enemies Beta]] modifier active.

==Appearance==
{{Tabber
|Current
|The '''Mystery''' is a translucent glass green humanoid with a glowing orange question mark on its torso. It is faceless and small green question marks are emitted from its torso when it is killed.
|Enemies Beta
|The [[Enemies Beta]] version of the '''Mystery''' had a pastel light green skin color, with its torso and legs being a darker shade of green with a plaid stitch mark pattern on them. It also had a desaturated yellowish-orange question mark on its chest.
|Version 3
|The third version of the '''Mystery''' is similar to the current version, except it had a drooling zombie face and did not emit green question marks upon death.
|Version 2
|The second version of the '''Mystery''' is similar to the third version, except it was more translucent, and its skin color was a lighter shade of green. Its question mark did not glow either and had a vibrant orange color.
|Version 1
|The first version of the '''Mystery''' is similar to the second version, except it was blue.
}}

==Enemy Spawned==
The '''Mystery''' is able to spawn more [[enemies]] after its debut. ''Italic'' names can be spawned from the '''Mystery's''' debut.

}}

==Strategy==
*The greatest danger mid-game '''Mysteries''' pose is the off chance that many high-health enemies spawn from a horde of them.
**Weaker enemies that spawn, like [[Abnormal]]s, [[Quick]]s or [[Hefty|Hefties]], are easy to deal with by the time '''Mysteries''' debut and are not a cause for concern.
**Stronger enemies like the [[Lead Boss]] are the main threats when dealing with mid-game '''Mysteries'''; most defenses are only strong enough to deal with a few of them. As '''Mysteries''' are random with their spawns, spikes in enemy count and health are sudden and unforeseen and can easily overwhelm the defense.
***These moments are the worst-case scenario and do not always happen, though it is usually better to be prepared for such situations.
***Alternatively, you could play on maps with the [[Enemies Beta]] modifier active, which replaces the '''Mystery''' with the [[Breaker2]], completely eliminating these possibilities.
*Due to the nature of mid-game '''Mysteries''', lots of defense should be prepared to deal with the worst-case scenario.
**Fairly cheap high-DPS towers like the [[Minigunner]] are very useful.
**Strong mid-game towers like the [[Golden Crook Boss]] or [[Militant]] are effective, though weaker ones like the [[Scout]] may falter.
**As '''Mysteries''' and their spawns come in hordes, towers that can deal damage to multiple enemies like the [[Shotgunner]], [[Pyromancer]], [[Gladiator]] and [[Demoman]] are effective.
**The [[Military Base]] is quite good against '''Mysteries'''. The [[Tank (Unit)|Tank]] and [[Railgun Tank]] are particularly effective with their high health and splash damage capabilities.
**Extra hidden defense should also be considered, especially if the past waves of [[Invisible]]s have proved troublesome.
*Later on in the game, '''Mysteries''' are able to spawn other enemies, some of which may be threatening.
**The [[Circuit (Hardcore)|Circuit]] from [[Hardcore Mode|Hardcore]] mode is the most troublesome. It should be killed before it is able to speed up other enemies, which is usually doable with enough DPS. High-DPS towers like the [[Accelerator]] paired with support towers like the [[Commander]] should do the trick.
*Be aware that you do not earn any cash from damaging enemies that the '''Mystery''' spawns in every mode.
*The enemies that spawn from the '''Mystery''' do not need to be killed for wave progression to occur.
**If you are speedrunning a map, you should focus on killing the '''Mysteries''' first by setting your towers' targeting to ''Weakest'' before moving onto the enemies that spawn.
***Be aware that if you get a lot of high-health enemies, like the [[Lead Boss]], they may outrun your towers if you switch target settings.
****Using towers that can hit multiple enemies can remedy this. The [[Gladiator]] is particularly good here.
*The [[Frost Blaster]], [[Sledger]] and [[Electroshocker]] are the best stalling towers against '''Mysteries''' as they can hit multiple enemies at once, though others like the [[Toxic Gunner]] are still viable.
*If there are some '''Mysteries''' at the end of the map, do not kill them, as they may spawn high-health enemies, severely reducing your base health or even killing you.

==Trivia==
*The '''Mystery''', alongside its stronger counterpart, the [[Mystery Boss]], have been slowly phases out of all modes and replaced by [[Breaker2]] and [[Breaker4]]. They now only appear in [[Hardcore Mode|Hardcore]], if the map does not have [[Enemies Beta]].
**Despite this, enemies like '''Mystery''' have not been fully phases out. Certain new events contained enemies which functioned similarly to '''Mysteries''', these being the [[Enigma]] and [[Frost Mystery (Operation I.C.E)|Frost Mystery]] from [[Operation I.C.E Event]].
*The appearance of the '''Mystery''' was originally based on the [[w:c:roblox-tower-battles:Mystery|Mystery]] from ''Tower Battles''.
*When the [[Super Mystery]], [[Ultra Mystery]] and [[Uber Mystery]] were in the game, the '''Mystery''' was the only mystery enemy not to have glowing eyes.
*Prior to the [[Overhaul v1.0|Overhaul Update]], in regular [[Fallen Mode|Fallen]] mode, the '''Mystery''' could spawn the [[Rusher (Polluted Wasteland)|Rusher]], even though it is a [[Polluted Wasteland]] enemy and did not appear naturally in regular [[Fallen Mode|Fallen]] mode.
*The '''Mystery''' and [[Mystery Boss]] can learn to spawn new enemies even before its first wave appearance.
*The question mark on the '''Mystery''' is a re-textured version of the {{RLinkC|1028826|Question Mark}} accessory from the Roblox catalog.
*Prior to the [[v1.1.0|Entity System Update]], '''Mysteries''' summoned from the [[Summoner Boss]] could be stuck in the air.
*As the '''Mystery''' is always replaced by the [[Breaker2]] with [[Enemies Beta]] active, it is currently impossible to see the [[Enemies Beta]] appearance of the '''Mystery'''.
**It was possible to see it on [[Polluted Wasteland II]] before the [[V1.4.2|Halloween 2022 Update]].
