Bloons get pushed backwards or slowed after each hit.
~ BTD6 descrpiton


Knockback is the first upgrade of Path 3 for the Super Monkey in Bloons TD 6. It gives the Super Monkey the capability to push back or slow down bloons on each hit. It will push back bloons besides Leads and Ceramics by 25% backwards, slows down Leads or Ceramics (including their fortified variants) by 60%, or slows down MOABs and above by 30% (except the BAD, which cannot be slowed at all).

The Knockback upgrade costs $2,550 in Easy Difficulty, $3,000 in Medium, $3,240 in Hard, and $3,600 in Impoppable.

Tips[edit | edit source]

  • One 0-0-1 Super Monkey is useful against Round 40, including on Alternate Bloons Rounds. Addition of Berserker Brew/Stronger Stimulant makes it even more reliable. Obyn Greenfoot also increases pierce, but only from Level 11+, which cannot be done naturally by Round 40.
  • When looking for reliable sources of knockbacking, it is worth knowing how each of these cross upgrades interact.
    • 3-0-1 Sun Avatar can knockback up to 6 bloons per sunbeam, 3 sunbeams per shot, and at double attack speed. Additionally, it can pop Leads but not Purples (unless Strike Down the False MK is active). It has the default Super Monkey range, though its range could be further increased with the upgrade Ultravision.
    • 0-3-1 Robo Monkey can knockback up to 6 bloons per dart from its 2 separate arm attacks. It can pop Purples but not Leads. It has good range, and it can be further improved with the Ultravision upgrade.
    • 0-0-3 Dark Knight can knockback up to 5 bloons per dark blade, can deal +2 damage to MOAB-class, and it can be crosspathed with other paths for additional benefit, preferably Path 1 with the double attack speed and +2 pierce.
  • As of Version 12.0, the nerf to the knockback towards Ceramics makes it difficult to stall Super Ceramics in place. In fact, the new knockback effect to Ceramics is now similar to that on MOAB-class bloons.
    • Dark Knight restores full knockback to Leads, Fortified, and Ceramics, but it is rather difficult to utilize Dark Knight for an intended purpose of stalling Super Ceramics.

Version History[edit | edit source]

12.0
  • Nerf.png Knockback has decreased knockback for Leads, Fortified, and Ceramics (-100% --> -60%). Upgrading to Dark Knight restores the full -100% knockback.

Trivia[edit | edit source]

  • The icon for this is a yellow boxing glove impacting a bloon.
  • This upgrade is the only upgrade below Tier-3 that costs exactly $3000 on Medium for the upgrade alone.
    • The Knockback upgrade is also the most expensive of all Tier 1 upgrades in the game.
  • This upgrade costs the same as the Super Monkey did in BTDB Mobile since Version 4.6. Likewise in BTD6, Laser Blasts now costs the same as the Super Monkey does in BTD6.
