Ground Zero

"Ground Zero Ability: drops a single devastating bomb that destroys all bloons on screen except MOAB-Class Bloons."

- Bloons TD 5 Upgrade description

 is the final upgrade of Path 2 for the Monkey Ace. It costs $11900 on Easy, $14000 on Medium, $15120 on Hard. The Ground Zero ability is similar to the Super Monkey Storm. It wipes out all regular bloons and MOABs, and deals 350 damage to BFBs and ZOMGs. It is very useful for taking out tight bunches of bloons or bloons that look like they're getting away. Use it for emergencies. This upgrade changes the color of the Monkey Ace from gray to black.

The only real differences between the Ground Zero Ability and the Super Monkey Storm discouting the damage is that Ground Zero costs a large amount of in-game money and is reusable like other Special Abilities, without having to pay 50 to use it. Although this ability can still deal a significant amount to ZOMGs, it is still advised to pop the ZOMG first before using this ability if possible.

Trivia

 * As of April 2, 2013 the damage dealt by Ground Zero has been nerfed to 500. Prior to this update, the damage dealt by Ground Zero was enough to instantly destroy BFBs, but ZOMGs were extremely resistant to the Ground Zero.
 * As of an even later update, on September 26, 2013, it has been nerfed again, to 350.
 * The Monkey Ace doesn't get any pops from using this ability (The pop count does not increase when the Monkey Ace pops bloons using the ability.)
 * A common abbreviation for Ground Zero is G0 or GZ.
 * You still get money from bloons popped by this ability.
 * Ground Zero has the potential to give heaps of money, as when a mass of MOABs are destroyed by the ability, you can get $10000-$50000, even more effective than massing Supply Drop. (Tested on Android).
 * 2 Ground Zeros, when timed properly, can complete the MOAB Madness challenge.
 * This tactic can be used over and over for fast XP.
 * A Ground Zero will pop a D.D.T., but the Camo Regen Ceramics inside will survive the blast.
