Can pop camo by default.
Can pop lead with all upgrades tier 3 and beyond.
Can damage HTAs with the rail gun and gas for the left upgrades, the rotors for the middle upgrades, 4M, and 5M.
5R ability gives 6000 lives, then 300 frames later (10 seconds at normal speed), removes 5900 lives, leaving you with 1 if you had less than 5901 left.
3R can infinite stall bloons, but sometimes causes a regrow farm.

Extremely powerful when upgraded.
The helipad can be built anywhere, since the actual damage source follows the mouse.

Expensive.
Very weak without upgrades.
Weak against high tier MOAB-Class bloons.
Requires micromanagement.
The helicopters have collision, so you can only build so many before they get in each others' way.
