Black Bloon

"Black Bloons are immune to explosions and contain 2 Pink Bloons!"

- Message when first encounting Black Bloons along with White and Zebra Bloons in BTD 5.

The  is a Bloon that appears in all games of the BTD (and BSM2). It has an unique property - it is immune to explosions. It usually appears around rounds 20-25. When popped, it will split into 2 Pink Bloons (or 2 Yellow Bloons pre-BTD4).

Details
The Black Bloon is one rank above Pink Bloon in Bloons TD games, on the same tier as a White Bloon or a Purple Bloon. It is around the speed of a Green Bloon and leaks 11 lives (or 9 pre-BTD4) if it reaches the exit. Unlike the bloons a Black Bloon spawns, it splits into two Pink Bloons (or Yellow Bloons prior to BTD4) when affected by an attack that deals 1 damage. More damage pops the Black Bloon into its descendents, following the multi-layer health system of many bloons in the game. The Zebra Bloon and Lead Bloon are both of the Black Bloon.

In Bloons TD games and Bloons Pop!, the Black Bloon is immune to all explosive attacks without special upgrades or support. This is especially problematic for Bomb Shooters, which naturally are weak to these bloon types without accessing powerful higher-tier upgrades.

Comparison to a White Bloon

 * Black
 * It is immune to explosions, meaning it is immune to effects that more towers and upgrades have.
 * It moves 1.8 times faster than a Red Bloon (which is the same speed of a Green Bloon), and slower than a White.
 * They are encountered sooner in the games.

It could be said that the Black Bloon was formerly more powerful than the White Bloon, and thus was once the most powerful Bloon. In BTD1, only Bombs could pop frozen Bloons, so you needed bombs to have any use for Ice Towers. Also, since BTD1 does not have Snap Freeze, the Ice Tower could not deal damage. Because of this, more people used Bombs back then, and thus more people were affected by the Black Bloon's immunity to explosions.
 * White
 * It is immune to freezing - It is immune to fewer effects that towers and upgrades have.
 * It moves twice as fast as a Red Bloon, and faster than a Black.
 * They are encountered later in the games.

Quotes
"Black Bloons are nasty - they are small but they contain 2 yellows inside them. Oh did I mention they are IMMUNE TO BOMBS?!"

- Round 26 in Bloons TD 1

"80 black bloons. Enjoy."

- Round 40 in BTD1

"Just black bloons coming up. Lots of 'em."

- BTD1 round 37

"Lots and lots and lots of black bloons. More than ever."

- BTD1 round 44

"This is the last level. There are TONS AND TONS of black AND white bloons coming. Hope you have lots of lives left..."

- BTD1 round 50

"The good thing about black bloons is that they move slower than yellows."

- BTD1 round 32

"Lots and lots of yellows - more than a hundred even, followed by a bunch of black bloons."

- BTD1 round 29

"Lots of white, then black, then yellow bloons. The next level is going to hurt."

- BTD1 round 46

Trivia

 * In BTD3 and BTD4, a single pile of Road Spikes can almost take down an entire Black Bloon, leaving only a Red Bloon. In BTD5, one spike pile can pop a Black Bloon whole.
 * It is sometimes confused with the Bomb Bloon. Both deal with Bombs in some way.
 * In BTD1 and BTD2, because of its resistance to bombs, it is impossible to win the game using only Bomb Towers. In BTD3, BTD4 and BTD5, it is possible because of the Frag Bombs upgrade, and also, in BTD5, the Bloon Impact upgrade.
 * Strangely, Black (and also White) Bloons are small, yet containing two larger (Pink) Bloons.
 * However, in the flash version of Bloons TD 5, the Regrow property clears up this issue, as all Regrow bloons have the same size.
 * If the player upgrades a Frag Bombs Bomb Shooter to a Cluster Bombs Bomb shooter, the tower will not be able to pop Black Bloons anymore until upgraded to the Bloon Impact upgrade, because the bombs replace frags in the upgrade.
 * In Bloons TD 6, Cluster bombs and recursive cluster now produce fraggy explosions, essentially giving them normal damage type.
 * In BTD1, Black Bloons can not be popped at all while frozen because they are immune to Bombs, while frozen Bloons are immune to everything except Bombs, this makes it more powerful than the white bloon at times.
 * There are 4 Bloon types in the entire Bloons series that have multiple "parents" - Black Bloons, Ceramic Bloons (however, they also released from DDT on Bloons Monkey City, but with Camo and Regen properties) and Pink Bloons. The Black Bloon has the Lead Bloon and the Zebra Bloon and the Ceramic Bloon has the MOAB and the DDT.
 * There are 2 of them that have 3 "parents" - In Bloons TD 4 Black Bloons and Pink Bloons (whose parents are Blacks, Whites and Camouflage Bloons.
 * The Black Bloon and the White Bloon are the only Bloons smaller than the Bloons they spawn.
 * In BTD5, they can be popped by a Missile Launcher upgrade. This may be due to the fact that in the files, a 'missile' and a 'bomb' are set to two different things.
 * In Bloons TD 6, Striker Jones has an upgrade on level 5 that makes Black Bloons less resistant to explosives.
 * The Black Bloon makes a distinct "clonk" noise when hit by an explosion in BTD6.
 * There are no sounds for Black Bloon immunities in earlier games.
