Omnipopping Towers
Towers that can pop all types of bloons.

BTD1
The Dart Tower, Tack Tower and Super Monkey can pop all non-frozen bloon types in BTD1 without any upgrades. However, the damage type they use is not to be confused with the Normal damage type, which enables an attack to not only pop the aforementioned bloons, but also frozen ones.

BTD2
There are no omnipopping towers. The only way is to combine Bomb Towers with other popping towers (Ice Tower does not count).

BTD3
There are a few omnipopping towers. The most efficient at omnipopping is the Super Monkey with Plasma Blasts, as it is more efficient at destroying MOABs.

BTD6 generation and beyond
Towers will gain omnipopping as long as they both deal Normal damage and have Camo Detection, while not restricted by Target Bloon or Target Blimp.
