The Rainbow Bloon is a bloon that originally appeared in Bloons Tower Defense 2 and has appeared in every other BTD game since. It is the parent of two Black and White Bloons in BTD2 and BTD3, and the parent of two Zebra Bloons in BTD4, BTD5, and BTD6. Rainbow Bloons are quite fast, having a relative speed of 2.2 compared to a Red Bloon. They are faster than White Bloons but still slower than Ceramic Bloons. In the original Bloons, there is a Helium Bloon, which is also rainbow colored and is often confused with this type of bloon. It first appears on round 12 in BTD2 and BTD3 and on round 35 in later games.

Details[]

The Rainbow Bloon is one rank above Zebra Bloon (or Black Bloon and White Bloon prior to BTD4 and in BTD4's Mobile and DSi ports) in Bloons TD games. It is slightly faster than a Green Bloon and leaks 47 lives (37 lives pre-BTD4) if it reaches the exit. As per the multi-layer health system, a popped Rainbow Bloon splits into two Zebra Bloons when affected by an attack that deals 1 damage. More damage pops the Rainbows Bloon into its descendants, following the multi-layer health system of many bloons in the game. The Rainbow Bloon's parent is the Ceramic Bloon.

In Bloons TD games and Bloons Pop!, the Rainbow Bloon lacks any immunity but possesses offspring with relentless immunity against explosive and freezing. In most games, except Bloons TD 4, BTD5 Mobile and other mobile counterparts, a Rainbow Bloon dealt with more than one damage can bypass explosion-immune and freeze-immune layers regardless of damage type of that attack. An example of this is Really Big Bombs popping a Rainbow into 8 Pink Bloons with an explosion dealing 3 damage, despite the explosion being unable to deal damage to Blacks or Zebras directly.

Bloons TD Battles 2[]

Rainbow Bloons can be sent starting from Round 12. Spaced Rainbows cost $70 and give 3 eco per slot, each slot sending one Rainbow with small spacing. Grouped Rainbows replace the Spaced Rainbows option on Round 13, and cost $250 for 4 moderately grouped Rainbows, and increases the reward to 6 eco.

Natural Rainbows start appearing on Round 17.

Rainbow Bloons move at a base speed of 55, equal to 2.2 RBS.

Bloons Pop![]

High hit point Bloon
~ Short description

Rainbow Bloons have no particular bloon weaknesses, as stated on the Bloonspedia entry for Rainbow Bloon. However, it has many descendants of bloon. Its direct child is the Zebra Bloon, followed by a 50-50 chance of either a White Bloon or Black Bloon.

Combat[]

Rainbow Bloons are relatively strong bloons because, although its own layer is easy to pop, it can spawn a large total of bloons, summing up to 47 bloons per Rainbow Bloon. It is also relatively fast too, having a relative speed of 2.2 compared to a Red Bloon. Many towers or towers with high upgrades are well recommended to dealing with these bloons.

Super Ceramic behavior[]

In Rounds 86+ in BTD5, Rounds 30+ in both Bloons Monkey City Flash and Mobile, Rounds 35+ in BTDB Flash, Rounds 43+ in BTDB Mobile, and Rounds 81+ in BTD6, with the introduction of Super Ceramics, Rainbow Bloons will only spawn one Zebra Bloon when popped. Additionally, that Zebra will only pop into one White Bloon, and that White will only pop into one Pink Bloon, greatly reducing the total amount of child bloons in late-game.

Monkey vs Monkey (BMC)[]

Rainbow Bloons are unlocked by the Multilayer Tech upgrade. It costs City Cash3500 and BloonstoneIcon5 to research at the Bloon Research Lab. In BMC Mobile, Multilayer Tech requires the Bloon Compression Tank.

Update History (Bloons TD Battles Mobile)[]

The Rainbow Bloon (specifically the grouped version) has become notorious among players for being hard to defend, especially when paired with the regrowth property, having earned the nickname Regrow Rainbows Of Doom (RROD). However, it's since been nerfed overall via game updates to make it more costlier and less effective to send.

Trivia[]

  • It changed its appearance twice throughout the series. In Bloons TD 2 and Bloons TD 3, it has a red spiral, and looked like the Helium Bloon in Even More Bloons, while in Bloons TD 4, it has a vertical rainbow pattern. In BTD5 it was just different color lines that don't fade/collide together
  • In BTD3, it makes its first appearance before any of its children.
  • When an Ice Tower upgraded with Snap Freeze freezes a Rainbow Bloon, the Rainbow Bloon will pop leaving behind two Zebra Bloons in its place. Though they are immune to bombs and ice, the Zebra Bloons will be frozen. This one of the few known ways to freeze a Zebra Bloon, the other way is to use the Viral Frost.
  • In BTD2 and BTD3, it is the only bloon to contain two different types of bloon, while in BTD4 and BTD5, it is the Zebra Bloon. In BTD6, the B.A.D. does too.
  • Although the Rainbow Bloon is a rainbow-colored bloon, it is not the parent of any bloon that is any color of the rainbow.
  • The Rainbow Bloon in Bloons Super Monkey only has 6 layers.
  • Before Round 35 in Bloons TD 4, the game tricks the player by saying there are 3 Rainbow Bloons at the end of the level. There are 3 Rainbow Bloons at the end of the level, but only after 5 are seen earlier in the level.
  • In BTD2, round 43's pre-round comment is misspelled and it says "Letting a raindbow bloon escape will cost you the princely sum of 37 lives!". "Princely sum" means a humorously large amount.
  • The official last appearance for Rainbow Bloons in BTD5 is Round 82, where Camo Regen Rainbows among with B.F.Bs incoming, though it wouldn't be a problem because camo detectors used in Round 78 can usually handle it, it also gives Ice Shards and Bloon Area Denial System ability come through it's spotlight since they can hit the B.F.Bs from behind.
