Blowback

Blowback is characterized as a status effect as sending bloons away from the exit. It was introduced in Bloons TD 4 with the Monkey Apprentice's Summon Whirlwind upgrade. In Bloons TD 5, the Ninja Monkey's Distraction and Heli Pilot's Downdraft upgrades can both do this too. It is part of the damage types family.

Blowback is represented on the Bloons Wiki as, the upgrade icon for Downdraft in Bloons TD 6, as it depicts the wind the Heli Pilot makes from flying pushing the bloons away from the exit.

Blowback will always have RNG incorporated as the game needs to decide how far bloons will be sent away from the exit. Distraction is different. While the game needs to decide how far the bloons will be sent, just like Downdraft, the game also needs to decide which bloons will be sent. That is also determined by RNG.

Superstorm and Psi's Psionic Scream both have a unique blowback since they are the only ones of of their kind to affect MOAB-class Bloons.

All attacks require an upgrade in order to receive the Blowback status effect.
