ZOMGs [sic] known as the Zeppelin of Mighty Gargantuaness. The epitome of Bloon technology, a gigantic very slow bloon that contains 4 BFBs.
~ Bloon Research Lab description of the ZOMGs upgrade

The Zeppelin of Mighty Gargantuaness, commonly abbreviated as the "Z.O.M.G.", is a MOAB Class Bloon that made its debut in Bloons Tower Defense 5. The Z.O.M.G. is very hard to pop and used to be the strongest Bloon and MOAB Class Bloon in Bloons TD history until it got overtaken by Bloonarius the Inflator. When the Z.O.M.G is almost popped, it shows a Bandage on its skull and the left engine on fire. It first appears on Round 85 in Bloons TD 5, the final round on Hard. The Z.O.M.G. is a large zeppelin that's mainly black in color with a cropped skull on top. The Z.O.M.G. was first seen at the end of the BTD5 trailer that was released on November 29, 2011.


It has an extremely high RBE of 16,656 and takes 4,000 damage to pop it, whereupon it releases 4 B.F.B.s. Without a proper defense, its children can rush through the level and end the game. On Round 85 in Bloons Tower Defense 5, there is only one Z.O.M.G. (five in Impoppable Difficulty), but in later rounds there are multiple Z.O.M.G.s, increasing even more and more in later rounds.

The Z.O.M.G. is different to the B.F.B. and the M.O.A.B. because it is immune to the Monkey Buccaneer's Monkey Pirates grappling ability, receives 350 damage from the Monkey Ace's Ground Zero ability, 753 damage from the Bomb Tower's upgrade MOAB Assassin, and 1000 damage from Bloon Annihilation Ability. However, the Bloonchipper's Super Wide Funnel upgrade can still suck in the Z.O.M.G and eventually pop it (note that this does not work in Bloons TD Battles Mobile), and the Monkey Sub's upgrade, First Strike Capability can destroy an entire Z.O.M.G, children and all.

While bloons can normally be allowed to leak with loss of life, the Z.O.M.G. has an RBE (red bloon equivalent) of 16,656, making this strategy practically impossible even with the use of Healthy Bananas. However, it is possible to leak a Round 85 Z.O.M.G. whole and survive with the use of several Support Chinook and supply drop abilities, though this is only possible on Steam or mobile.

Z.O.M.G Layer (Blimp Health)Edit

Like the M.O.A.B. and the B.F.B, the Z.O.M.G layer also has 4 health stages, as you can see in the picture on the right. When you reduce 650 health from the B.F.B layer and the Z.O.M.G layer, the B.F.B layer is almost popped, while the Z.O.M.G layer doesn't have even a little damage. You can see little damage on the Z.O.M.G when you reduce to it more than 1,000 hits and less than 2,000 hits. Between 2,000 hits and 3,000 hits, the Z.O.M.G has serious damage. Between 3,000 hits and 4,000 hits, the Z.O.M.G has critically serious damage and there is a bandage on its skull. After 4,000 hits, the Z.O.M.G layer is destroyed, and it releases 4 Brutal Floating Behemoths (B.F.B.s). It should also be noted that in Bloons Monkey City (or with BTD 5 freeplay) the higher the round you are, the faster and stronger the Z.O.M.G and all other Bloons get. This is very noticeable if you are playing on Contested Territory.

Differences Between BTD5 Flash and BTD5 MobileEdit

Aside from having a different appearance, the Z.O.M.G. does not have many differences between the flash versions of BTD and the mobile versions.

Nerf Absolute Zero ability can slow down ZOMGs.

Buff When the Z.O.M.G. is on its last stage of health, it moves forward a bit.

Update History (Bloons TD Battles Mobile)Edit

The Z.O.M.G has been buffed via game updates, which have made it harder to defend.

Note: The buffs and nerfs refer to according to the power of the ZOMG, and don't necessarily reflect whether it is good or not for the player or opponent.

Initial Release

Nerf Z.O.M.Gs (along with the other MOAB class bloons) can now be stalled by Supa-Vac for 8 seconds.

Nerf Z.O.M.Gs (along with the other MOAB class bloons) have half the health of their BTD5 counterparts before getting destroyed (4000 HP → 2000).


Nerf Artillery Battery Pop and Awe ability now stuns ZOMGs for 0.5 seconds.


Buff Supa-Vac now only holds Z.O.M.Gs in place for 2 seconds.


Buff Fast Cooldown Z.O.M.Gs added. They cost $10,000, take around 1 second to send, and change the income by -$1500.


Buff Z.O.M.Gs (along with the other MOAB class bloons) have increased health and speed ramping (Speed: +15% per round → +20%; Health: +5% per round → +40%).


Buff Spaced and Fast Cooldown Z.O.M.G income penalty reduced (-$1500 → -$600).

Buff Super Wide Funnel no longer sucks in Z.O.M.Gs.

Buff Supa-Vac no longer stalls Z.O.M.Gs.


Nerf Fast Cooldown Z.O.M.G income penalty increased (-$600 → -$900).


Nerf MOAB Assassin deals more damage (700 → 1000). This means that Z.O.M.Gs can now be destroyed in 2 uses of the ability instead of 3.



  • Z.O.M.G.s are the second slowest among all Bloons, but can outrun a Lead Bloon affected by Permafrost, glue and Sabotage Supply Lines in effect.
  • In the picture of the Z.O.M.G. on Bloons Tower Defense 5 Mobile as seen to the right, it's eyes and skull are missing and the fore-end is flat instead of pointy.
  • In Bloons TD 5 Mobile, it moves slightly forward when it is at its last stage of health. This is unintentional.
  • Z.O.M.G.s will appear no earlier than round 85 (the final round in Hard Mode), unless in Daily Challenges or Mastery Mode.
  • It takes 364 piles of Road Spikes to pop the ZOMG layer, and 1515 piles to pop it completely.
  • The RBE in game suggests that the Z.O.M.G. layer has 4000 health but in reality it takes 5 MOAB Assassins, 21 road spike piles and 4 explosive pineapples to pop the first layer, because the MOAB Assassin deals reduced damage (753 damage) per shot.
  • For humor, the Z.O.M.G.'s last stage of health depicts a bandage on the skull.
  • The Z.O.M.G, like other M.O.A.B-class Bloons, will increase in strength and speed each round after Round 103.
  • In the official trailer of BTD5, the Z.O.M.G. appears for only 2.5 seconds.
  • The original Bloons Tower Defense game had a total RBE of 30,160, approx. 2 Z.O.M.G's.
  • The Z.O.M.G. can only be slowed/stopped by Sabotage Supply Lines, Cripple MOAB and Pop and Awe.
  • If the player uses a Sabotage Supply Line before a Z.O.M.G. comes out, it only slows the Z.O.M.G., the first B.F.B. of the 4 that come out, and the first M.O.A.B. of the 4 that come out of the slowed B.F.B.s. If the Ability is used while a Z.O.M.G. is out, the first of the 4 B.F.B.s is the only one not slowed, and the same with the M.O.A.B.s from the slowed B.F.B.s.
  • In the trailer for Bloons TD 5 iOS, it is shown to have a mouth, as it is in the Ninja Kiwi avatar unlocked at Rank 40.
  • This M.O.A.B. Class Bloon can be sucked by the Bloonchipper Super Wide Funnel upgrade, in all games featuring this bloon except for BTD Battles Mobile.
  • In BTDB, its income change is -$1500, the greatest reduction of any bloon. This was recently changed on BTD Battles Mobile to -$600 for the spaced variant, and -$900 for the fast cooldown variant.
  • It takes 7 MOAB-SHREDR (1/3) spike factories to take down a whole Z.O.M.G and bloons it spawns on Monkey Lane.
  • It takes 9 Ground Zero bombs to destroy the outer layer of a Z.O.M.G. and 14 to destroy it and all bloons it spawns.
  • A Bloon Area Denial System, 2 Laser Cannons and a Hydra Rocket Pods Dartling Gun can completely destroy a whole Z.O.M.G. in the Jungle Totems track in BMC.
  • A single Z.O.M.G can be easily dealt with with the use of the First Strike Capability.
  • There is an indicator of a Z.O.M.G. on a DDT tile if there is more than 27 rounds on a tile. It will appear on rounds 26-30.
  • The Z.O.M.G. is considered by some to be the final boss of the game, though this is debatable as the game continues after beating it, and the next round features no less than 3 of them.
  • In Bloons Monkey City Mobile, when the player first encounters a Z.O.M.G., the Army Monkey will warn the player about the Z.O.M.G., but he doesn't show it directly.
  • Compared to reality, if a Red Bloon had a diameter of 4 centimeters, the length of a Z.O.M.G would be between 20 and 30 meters.
  • The Z.O.M.G strongly resembles the Christmas spoilers' blimp from the movie Saving Santa.
  • The Z.O.M.G contains 6,100 bloons. (6,101 including itself.)
  • The Z.O.M.G is missing from Bloons Super Monkey 2.
    • This may be because the Z.O.M.G would take up half the screen with its bulk.
    • A recent update in BSM2 mobile included the latest boss for Helium Heights, which appears to be a scrapped ZOMG.
  • Ninja Kiwi released the Z.O.M.G by stating, "Prepare for the Z.O.M.G, the Zeppelin... Oh... My... God... IT'S HUGE!"
  • The skull on the Monkey Buccaneer's hat resembles the skull on the Z.O.M.G, with one of the only noticeable differences being the skull on the Z.O.M.G having green eyes.
  • In BTD5 the Z.O.M.G. does not start taking damage until it is about 33% on screen (just starting to see the green eye symbols).
  • Some players call the ZOMGs as "Zoh My Gods".
