__TOC__
==Description==
'''Mechanical Rot''' is the final boss of the second [[Halloween 2025 Live Events|Halloween 2025 Live Event]] in [[Nil Zone]].

'''Mechanical Rot''' has three abilities:
#Its first ability is ''Minigun'', where '''Mechanical Rot''' will start firing its right arm machine gun in a sweeping fashion, stunning towers for 6 seconds and dealing 50 damage to units per tick.
#The second ability is ''Cannon'', in which '''Mechanical Rot''' will fire six explosive pumpkins at different towers. These pumpkins would explode upon impact, creating green smoke with a radius of 6 that stuns all towers hit by the explosion for 6 seconds while also dealing 50 damage to units.
#The last ability is ''Summon'', where the '''Mechanical Rot''' starts laughing anywhere between 6 and 16 seconds. During this, it will summon enemies, each with their own chance to be summoned and delay before the '''Mechanical Rot''' can summon another enemy.

==Strategy==
As this enemy only appears through [[Sandbox Mode|Sandbox]] mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without [[Sandbox Mode|Sandbox]] mode in [[Nil Zone]] is listed instead.
*High DPS towers like the [[Accelerator]], [[Turret]], [[Engineer]] and [[Golden Minigunner]] are very effective against the '''Mechanical Rot'''.
**Stun immune towers like the [[Pursuit]] or [[Ranger]] can also be useful as they cannot be stunned by it.
**The [[DJ Booth]] and [[Commander]] can be also helpful at boosting your towers' range and firerate respectively.
*The [[Medic]] is quite useful, as it can protect your towers from '''Mechanical Rot's''' stun while also providing protected towers with buffs.
*As the '''Mechanical Rot''' initially spawns with [[Boss]] in the [[Nil Zone]], it cannot be stalled through most methods.
**Stun towers like the [[Warden]], [[Electroshocker]] or [[Archer]] cannot stun it but only slow it down.
**Freezing towers like the [[Freezer]], [[Cryomancer]] or [[Elementalist]] similarly are unable to freeze it, but can still apply chill to it.

==Trivia==
*Originally, BelowNatural wanted to name this enemy something along the lines of '''Corrupted Jack O' Bot'''. It ended up being given the name '''Mechanical Rot''' after a suggestion from Nim.<ref>[[File:CorruptedJackoBotProof.png|280px]]<br/>https://discord.com/channels/735394249863987241/735394249863987244/1464387911184154803 (Tower Defense Simulator Wiki Server)<br/>https://discord.com/channels/735394249863987241/735394249863987244/1464389369954566328 (Tower Defense Simulator Wiki Server)</ref>
*The '''Mechanical Rot''' is a reimagined version of the [[Mechanical Rot (Legacy)|Mechanical Rot]] from the legacy [[Hidden Wave (Legacy)|Hidden Wave]].
**Based on its [[Logbooks|Logbook]] and its appearance, this version appears to be the [[Jack-o-Bot]] actor who was warped into the [[Nil Zone]] sometime after the [[The Haunted Past]].
***Through logbooks of the other actor enemies, it can be inferred that this most likely happened at the same time as the "''Glitch''" which prevented [[The Great Finale]] from happening properly.
*The laugh that plays when it uses its ''Summon'' ability is the same laugh as the [[Lord Sinister]] laugh.
