~ Upgrade description in BTD6.

Official BTD6 artwork

The Energizer is the final upgrade of Path 1 for the Monkey Sub in BTD6. It makes Heroes earn XP 50% faster, reduces cooldowns of all water Monkeys in the radius by 50% (doesn't stack with Bloontonium Reactor), as well as reducing ability cooldowns for ALL other towers on screen by 20%. It also increases the pierce of the Bloontonium Reactor from 70 to 1000 and the damage from 1 to 3.

Update History (BTD6)Edit


Buff Energizer now pops more bloons (30 --> 1000)

Buff Energizer also reduces ability cooldowns of all other towers on screen by 20%.


Buff Energizer radiation deals more damage per pop (1 --> 3)


Buff Now (correctly) applies bonus XP to Heroes.



  • The description used to be "Hero earns XP 50% faster while in Energizer's radius. Cooldowns for abilities of water Monkeys in the radius are halved." but has changed due to the changes in Version 2.0.0.
  • The increased Cooldown reduction for Water monkeys also applies to any tower placed on the Carrier Flagship.
  • When crosspathed with upgrades on the bottom path, two guns appear on the bottom of the Energizer.
