Damage type

Damage types are a game mechanic in the Bloons TD series and in Bloons Pop!. They are a property of damage that determines which types of Bloons the damage can or cannot be dealt to. This mechanic was introduced in the mobile versions of Bloons TD 5, Bloons TD Battles, and Bloons Monkey City as a way of standardising the immunity system used in the Flash versions of these games and in all prior games.

Extra damage to Ceramic Bloons and extra damage to MOAB-Class Bloons use separate damage types that can only deal damage to those Bloons. For example, MOAB Mauler's explosion deals 1 Explosive damage and 9 MOABMauler damage, so it deals 1 damage to regular Bloons and 10 damage to MOAB-Class Bloons. Due to a bug, attacks with multiple damage types increase the tower's pop count multiple times.

In BTD5 and BMC (but not BTD Battles), MIB allows Juggernaut damage to apply to MOAB-Class Bloons and allows MOABMauler damage to apply to Ceramic Bloons. This does not apply to the Spike Factory in BMC except for Spike Storm.

Bloons TD 6

Type				Frozen			Notes
Sharp							Towers that deal Sharp-type damage can be buffed by the Sharpening Stone from Geraldo's Shop. The Flint Tips Relic Knowledge causes Sharp damage to apply a damage over time effect.
Shatter							—
Explosion							Also deals +1 damage to Dynamite Bloons.
Fire
Cold							While Cold and Glacier damage is able to pop frozen Bloons by default, both the Ice Monkey and Cold Sentry are unable to target or damage frozen Bloons. The Ice Monkey can only target and pop frozen with Re-Freeze; it cannot be overridden with Monkey Intelligence Bureau. Projectiles that deal Cold or Glacier damage reduce heat from Blastapopoulos.
Glacier
Frigid							Attacks and damage over time effects that deal Frigid, Energy, or Plasma damage deal more damage to Bloons haunted by Corvus. Projectiles that deal Frigid, Energy, or Plasma damage add more heat than normal projectiles to Blastapopoulos.

Plasma
Acid							—

Internally, damage types in BTD6 are determined by their Bloon weaknesses, specifically an immuneBloonProperties value as a decimal integer equal to the value of its binary flags, starting from the left: glass (64), immune (32, no attack uses this property), frozen (16), Purple (8), White (4), Black (2), Lead (1).

• Normal: 0
• Shatter: 1
• Explosion: 2
• Glacier: 4
• Cold: 5
• Fire: 8
• Frigid: 12
• Sharp: 17
• Acid: 64
• Plasma: 72
• Energy: 73

Changes between updates

• Prior to version 25.0 of BTD6, the Cold and Glacier types worked differently:
  • Cold could not pop frozen by default, while Glacier could.
  • Both types could pop Lead by default, but the Ice Monkey's attack had a special property that caused it to ignore Lead Bloons unless buffed.
• The Frigid type was introduced in version 45.0, while its name was first revealed in version 48.0 update notes.
• Plasma and Fire were originally functionally identical and treated as the same damage type by the game's data. In version 52.0, they were separated to allow for different interactions with Glass Bloons (Fire can pop them but Plasma does not) and Dynamite Bloons (Take +1 damage from Fire, Plasma works as normal).
  • Prior to version 52.0, Plasma and Energy had a bitstring value of 8 and 9, now it's 72 and 73. Fire has a bitstring value of 8, just like old Plasma.
• Normal and Acid were also originally functionally identical and treated as the same damage type by the game's data. In version 53.0, they were separated to allow for different interactions with Glass Bloons (Normal can pop them but Acid does not).

Bloons TD Battles 2

Bloons TD Battles 2 uses a similar system to older versions of BTD6. The Normal type is known as Unstoppable in this game.

Bloons Adventure Time TD

This article is in need of research. You can help out by editing this article or discussing your findings on the talk page. The editor who added this notice elaborates: How do PB and Water Nymph's combined damage types work?

Similar to older versions of BTD6, sources of damage in Bloons Adventure Time TD are able to have multiple damage types. Princess Bubblegum and Water Nymph are able to pop all Bloon types, despite her attack dealing sharp/energy damage, neither of which should be able to pop Lead Bloons.

While most characters and allies list the damage type of their main attack on their profile, some only display "N/A", including all characters and allies with normal, cold, or multi-type damage.

Compared to BTD6, the cold type can pop Lead Bloons, and the glacier type is omitted. While the Acid type does exist in the game's programming, it is completely unused.

Bloons Pop!

Bloons Pop! uses a simpler damage type model compared to Bloons TD 6. Since frozen Bloons do not gain any immunities in this game, there are no damage types that are only distinguished by their ability to pop frozen.

The names of most damage types are given in the bios of certain monkeys in their Bloonspedia bios, though the name of the normal type is not specified in-game and is only given in internal data.
