__TOC__
==Description==
The '''Mystery Boss''' is an [[Enemies|enemy]] that will spawn a random enemy upon its death. The enemy spawned depends on the mode and wave. As the name implies, the '''Mystery Boss''' mostly spawns bosses that have high health or enemies that are quick, meaning that it is a very dangerous enemy. Its health depends on the mode you are playing on.

The '''Mystery Boss''' appears in the [[Sandbox Mode|Sandbox]] exclusive [[Legacy Molten Mode|Legacy Molten]], [[Legacy Fallen Mode|Legacy Fallen]] and [[Golden Mode|Golden]] modes.

The '''Mystery Boss''' is spawned by the [[Mystery Summoner]], [[Summoner Boss]], [[Necromancer Boss]] and [[Void Reaver]]. The [[Grave Digger]] used to be able to summon it in the [[Easy Mode|Easy]] mode. If a map has the [[Enemies Beta]] modifier active, it is not spawned by these enemies as they spawn the [[Breaker4]] instead.

The '''Mystery Boss''' is replaced by the [[Breaker4]] in any map with the [[Enemies Beta]] [[Modifiers|modifier]] active.

==Appearance==
The '''Mystery Boss''' is a large translucent humanoid with a glowing orange question mark on its torso. All of its body parts are colored indigo and are made of a glass material. Its left leg is twisted and its head is pointing slightly downwards as it walks. It is also faceless.

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

==Strategy==
*High DPS towers are recommended, supported by the [[DJ Booth]] and [[Commander]].
*The '''Mystery Boss'''' random nature is not as impactful as the [[Mystery]]'s. However, some enemies still pose a significant threat without the right towers.
**An overflow of [[Fallen Hero (Legacy)|Fallen Hero]]es, [[24 Karat]]s or [[Molten Titan (Legacy)|Molten Titan]]s may be overwhelming with their massive combined health.
***In general, high DPS towers accompanied by support towers is the best answer against all high health enemies.
**[[Shadow Boss]]es may be dangerous without adequate hidden defense.
***Hidden defense should be strong. Most high DPS towers have hidden detection, so [[Shadow Boss]]es should not be a major issue with them.
*As '''Mystery Bosses''' and their spawns come in hordes, towers that can deal damage to multiple enemies like the [[Mortar]], [[Rocketeer]], [[Gladiator]] and [[Executioner]] are effective.
**However, some of these towers may not fare so well against high health enemies. High DPS towers should be used to counter those.
*Be aware that you do not earn any cash from damaging enemies that the '''Mystery Boss''' spawns in every mode.
*The enemies that spawn from the '''Mystery Boss''' do not need to be killed for wave progression to occur.
**If you are speedrunning a map, you should focus on killing the '''Mystery Bosses''' first by setting your towers' targeting to ''Weakest'' before moving onto the enemies that spawn.
***Be aware that the spawned enemies may outrun your towers if you switch target settings.
****Using towers that can damage multiple enemies can remedy this.
*The [[Sledger]], [[Frost Blaster]] and [[Electroshocker]] are probably the best slowing towers against '''Mystery Bosses''' as they can hit multiple enemies at once, though others like the [[Toxic Gunner]] are still viable.
**Be aware of the enemies' size and immunities, which may cause some of these towers to be less effective.
*Some enemies from the '''Mystery Boss''' like the [[Giant Boss]] have defense, so defense dropping towers can be useful.

==Trivia==
*There was a glitch whereby the '''Mystery Boss''', after its death, could go to the next turn and stop there with its walking animation still playing. This was just a visual bug and did not affect gameplay in any way.
*For some reason, the '''Mystery Boss''' debuts on wave 29 for [[Golden Mode|Golden]] mode.
**However, the text associated with the '''Mystery Boss''' appeared on wave 32, like [[Molten Mode|Molten]] and [[Fallen Mode|Fallen]] modes.
**The same thing occurs with the [[Fallen Hero (Legacy)|Fallen Hero]], [[Molten Titan (Legacy)|Molten Titan]], [[24 Karat]] and [[Super Toxic]] which all can be spawned on wave 38 from the '''Mystery Boss''', which is before their debut on wave 39 on [[Fallen Mode|Fallen]], [[Molten Mode|Molten]], [[Golden Mode|Golden]] modes and, formerly, [[Polluted Wasteland II]], respectively. However, this is intentional.
*Prior to the [[v1.1.0|Entity System Update]], summoned enemies from the '''Mystery Boss''' used to say "''Mystery's'' ______" instead of "''Mystery Boss's'' ______".
*The question mark on the '''Mystery Boss''' 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]], '''Mystery Bosses''' summoned by the [[Summoner Boss]] could be stuck in the air.
