Tech Terror

"Annihilation ability: Destroys most Bloons completely and utterly within blast radius."

- Official BTD6 description

 is the fourth Path 2 upgrade for the Super Monkey in Bloons TD 6. It corresponds to the Technological Terror upgrade in BTD5. Along with x0.8 attack cooldown (+25% attack speed), +2 pierce, and shooting green plasma balls instead of darts, it gains an ability to deal 2500 damage at up to 2000 bloons within the annihilation range (with a radius of 70), including Camos and Purples. Cooldown for the ability is 45 seconds. Main attack retains the critical hits system gained from Robo Monkey, every 15-20 shots gaining one critical hit inflicting 10 damage.

It costs $16,150 on Easy, $19,000 on Medium, $20,520 on Hard, and $22,800 on Impoppable.

Appearance
Tech Terror upgrades into a fully robotic monkey, which Ninja Kiwi states is constructed by Dr. Monkey. The robot has various fuel-infused pipes and internal construction that fuels the entirety of itself. Replacing its formerly bionically enhanced arms is a pair of arms that now act as plasma cannons. Tech Terror's head, while having the appearance of a monkey's head, is entirely mechanical; its head has the two fuel-infused pipes connecting from its head to its arms, its face is colored grey, has red circular eyes, and a wide grinded frown.

Tech Terror shoots green plasma balls through both of its arms. When its Annihilation Ability is activated, it produces an immediate pulse of green, accompanied with a robotic voice expressing its energy.

Adding Path 1 crosspaths obscures the Tech Terror's eyes with goggles that correspond to each Path 1 upgrade. Adding Path 3 crosspaths simply add orange stripes, one in the center for Knockback, or two stripes, one on each side, for Ultravision.

Summary
Tech Terror's Annihilation Ability is a valuable option for countering extremely clumped bloons. Annihilation Ability deals enough damage to wipe out Fortified BFBs and Fortified DDTs, both of which pose significant problems on Round 98 and Round 99, respectively. In terms of support, Village discounts for saving money when buying Robo Monkey are useful, and slowdown helps let the ability be chained to blast out more bloons in a single use. Stalling the ability is also helpful; don't blast too many bloons at once, and try to leave only a few bloons left so the ability can recharge further.

Its main attack only gains more pierce and attack speed in addition to popping Frozen and Leads in exchange for not popping Purples, only contributing a little bit to the Tech Terror's overall value. The bonus pierce and attack speed is mainly valuable for the mid-game, although the 0-4-2 crosspath allows affected bloons to become more clumped so that its ability can subsequently be chained together. In any case, still try to make use of its reasonably decent DPS, as it still is effective against weaker blimps and Super Ceramics even in the late-game.

Compared to Sun Avatar, which costs a little less than Tech Terror overall, Tech Terror has lower synergy potential, specifically when interacting with Alchemist buffs and Monkey Commerce discounts, but is compensated by its immense solo grouped popping power.

Tips

 * 2-4-0 Tech Terror is generally better for the +2 pierce and double attack speed, though 0-4-2 is good for the knockback power of the Knockback upgrade and camo detection from Ultravision.
 * Knockback can help clump up bloons together, to maximize potential for the Annihilation Ability.
 * Note that upgrading to Tech Terror prevents the Super Monkey from popping Purples without support, unless further upgraded to The Anti-Bloon. Be sure to provide backup defense against Purples, especially Camo Purples.
 * The Annihilation Ability is enough to entirely destroy up to Fortified BFBs in a single use. This can be utilized to deal with Round 98, but watch for the ability cooldown.
 * Clumping up the bloons helps with chaining Tech Terror ability at a denser group of bloons, making more use out of the ability. Slowdown supports such as Bloon Sabotage, MOAB Glue, and the Knockback upgrade help fulfill this role.

Bug Reports

 * [version unknown] If the Tech Terror's ability is used on the children of regrow bloons, (etc. zapping a rainbow bloon regrowed from another rainbow bloon's children) it will grant extra cash despite regrowed children bloons normally not giving cash. [unfixed as of 25.1]

Bug Fixes

 * [28.0] x-3-0 Robo Monkey and later were granted the Camo Prioritization option even though they cannot detect camo without Ultravision. Affects Tech Terror. Patched in 28.2.

Sounds
When relogging into a game having Tech Terror:
 * [Robotic voice] "Techno feel"

When activating Annihilation Ability:
 * [Robotic voice expressing an energetic pulse]

Trivia

 * In Bloons TD 6, its green plasma ball turns blue when above water. The Annihilation green ring remains green above water.
 * It is possible to win with 4 Tech Terrors in CHIMPS Mode. Along with placing the Super Monkeys within range of multiple Monkey Commerces to afford the Robo Monkey upgrades sooner, the hero Pat Fusty is used. This was even possible before Robo Monkey gained a substantial price cut in Version 22.0. An example can be found here.
 * Tech Terror is the only Tier 4 Super Monkey to ever cost less than $20,000 for the upgrade cost alone, as previous games including Bloons TD Battles Mobile feature a higher upgrade cost for its corresponding earlier counterpart, Technological Terror.
