__TOC__
==Description==
The '''Circuit''' was a very fast [[Enemies|enemy]] that appeared in [[Hardcore Mode|Hardcore]] mode (it used to appear in [[Polluted Wasteland]] in [[Fallen Mode|Fallen]] mode, replacing the [[Error]]). Currently, it can only be spawned in [[Sandbox Mode|Sandbox]] mode if the player has the Sandbox Plus+ [[Gamepasses|gamepass]]. The '''Circuit''' has quite high speed and somewhat high health. However, the '''Circuit''' has the ''Super Charge'' ability, letting it make itself and surrounding enemies faster, including major bosses (like the [[Fallen King (Legacy)|Fallen King]]). If you are really unlucky, multiple ''Super Charges'' can stack, making strong enemies extremely fast, even faster than the [[Error]] and [[Glitch]], making it a very dangerous enemy. The '''Circuit''' also has [[Stun Immunity]], which makes the [[Warden]] and [[Electroshocker]] only slow it down and making knockback towers not knock it back.

The '''Circuit''' can be spawned from the [[Mystery]] upon its death in [[Hardcore Mode|Hardcore]] mode, from wave 44 onwards.

==Appearance==
{{Tabber
|Current
|The current version of the '''Circuit''' is identical to its original version, except it has no mouth.
|Original
|The original version of the '''Circuit''' had a near complete blue appearance. It was slightly smaller than the average enemy. It had lightning particles in both hands and also had a blue threatening face, with blue glowing eyes. Some blue glitch particles could be briefly seen emitting from its torso. When a ''Super Charge'' occurred, electricity bolts can be seen above its head and a mouth beside its face.

==Strategy==
This strategy refers to the state of the game while the '''Invisible''' still appeared in the [[Hardcore Mode|Hardcore]] mode.
*This enemy must be defeated quickly. If not, it can speed enemies up to speeds greater than the [[Glitch]] and [[Fallen Rusher (Legacy)|Fallen Rusher]].
**This can speed up large enemies, such as the [[Slow King (Legacy)|Slow King]] and [[Vindicator (Legacy)|Vindicator]], and even major bosses like the [[Fallen King (Legacy)|Fallen King]]. Taking into account the ability to stack, this has the potential to be the most dangerous enemy in the game.
*Fast-firing towers, such as the [[Minigunner]], paired with the [[Commander]], are recommended to defeat the '''Circuit''' quickly.
**Long range towers, like the [[Ranger]], are also recommended.
**The [[Accelerator]] is not recommended against the '''Circuit''' as it will likely get out of its range before the [[Accelerator]] can charge up.
***Not to mention when the [[Accelerator]] targets an enemy it will not change targets before the enemy is killed, which may cause the '''Circuit''' to slip by.
***You can counter this by slowing down the '''Circuit''' with the [[Frost Blaster]], [[Toxic Gunner]], [[Sledger]], [[Harvester]] or [[Freezer]] to allow your [[Accelerator]]s to charge up and attack it.
*The [[Rocketeer]] and [[Mortar]] can damage hordes of '''Circuits'''. However, be aware that the '''Circuit''' may outrun the projectiles from these towers.
*The [[Electroshocker]], [[Toxic Gunner]], [[Sledger]], [[Harvester]] and [[Warden]] can be used to slow down the '''Circuit'''.
**Do note that the [[Stun Immunity]] that the '''Circuit''' has prevents stunning towers like the [[Electroshocker]] from stunning it, with it only being slowed down instead and it cannot be knocked back because of it.
*The [[Military Base]]'s [[Tank (Unit)|Tank]] and [[Railgun Tank]] are the best in halting the advance of the '''Circuit''' as it can easily sprint past all of your defenses.

==Trivia==
*The '''Circuit''', alongside the [[Speedy King]], the [[Circuit (Polluted Wasteland II)|Circuit]] from [[Polluted Wasteland II]] and the [[Commander (Pizza Party)|Commander]] enemy are the only [[enemies]] to make other enemies faster.
*The '''Circuit''' is the second (and currently only) [[Polluted Wasteland]] exclusive enemy to appear outside [[Polluted Wasteland]].
**The [[Rusher (Polluted Wasteland)|Rusher]] was the first enemy to appear outside it; it had a chance to be spawned from a [[Mystery]] when it died after wave 28 in [[Fallen Mode|Fallen]] mode. However, this no longer occurs.
**Due to [[Polluted Wasteland]] being removed, the '''Circuit''' is the only [[Polluted Wasteland]] enemy to appear in the game.
