NormalElite
Skulls 3 (normal) 7 (elite) Theme Primal One Introduced Version 27.0 Description • Sludge-dwelling Bloonarius spews Bloons as it takes damage. • When each skull on its health bar is reached, Bloonarius disgorges massive Bloon clusters onto the track. • Bloonarius' sludge infused husk makes it slow but extremely tough.

Bloonarius, titled The Inflator, is a Boss Bloon in Bloons TD 6, introduced in version 27.0. It is the first boss introduced to the game, and has the simplest mechanics relative to other bosses.

Bloonarius has a high amount of health and it spawns Bloons across the track as it takes damage. It spawns especially large waves of Bloons right in front of it when a skull on its health bar is reached.

Mechanics

Scattered Bloons

Each time Bloonarius loses 1% of its health, it spawns a certain number of Bloons all over the track. The number and types of Bloons it spawns depends on Bloonarius's tier and whether it is in Normal or Elite mode. These Bloons are distinguished from normally spawning Bloons by being covered by a dark green sludge. These Bloons are briefly immune to damage upon spawning and provide no cash when popped, but they do still add to towers' damage counters.

Skull ability

Upon reaching a skull, Bloonarius stops moving for 0.5s, scatters a lot of Bloons across the map (using the same mechanic as its usual scattering), and additionally spawns a dense pack of Bloons directly in front of it. Like scattered Bloons, the number and types of Bloons it spawns depends on Bloonarius's tier and whether it is in Normal or Elite mode. These Bloons are also briefly immune to damage upon spawning and do not generate cash, but they do still add to towers' damage counters.

Boss Rush

Damaging Bloonarius sends a wave of 2 Scattered Bloons every time it loses 15% of its current health. Popping Bloonarius makes it send a stronger wave of 4 to 12 Scattered Bloons. Every 10 pops, it triggers its skull ability, sending a stronger wave of 8 Bloons.

Strategy

For more in-depth strategies, see Strategy:Bloonarius (BTD6).

This section was last updated for: version 54.2

Compared to other bosses, Bloonarius is the most simple in terms of its mechanics, but should not be underestimated, specially in the lower tiers, as the Bloons it spawns when damaged and after reaching a skull can easily overrun unprepared defenses.

Tier 1 and 2 defenses are usually split on towers that can reliably damage the boss and towers with very high pierce that can handle the spawns.

In the first category Elite Defender is always a reliable option on Tier 1. A combination of Embrittlement / Super Brittle with Overdrive / The Tack Zone or Poplust / Avatar of Wrath shine due Bloonarius low speed, meaning it can stay on the range of those towers for longer. Spike Storm / Carpet of Spikes and Sticky Bomb / Master Bomber are only effective also on longer maps due Bloonarius high HP. M.A.D can also be used with caution on its placement as the pierce on its rockets can be consumed by the spawns before it reaches the boss. Towers that are used for damaging the boss should have their targeting set to Strong if possible to avoid getting them distracted with the spawns or to First if their help is needed to deal with the spawns.

For defending the spawns in the lower tiers, specially after a skull, towers with very high pierce are needed, common examples are multiple M.O.A.R Glaives / Glaive Lord, The Big One, Bloon Liquefier / The Bloon Solver, Jungle's Bounty / Spirit of the Forest, the abilities of the Blade Maelstrom and Geraldo's Blade Trap.

Tiers 3 and higher can be handled with expensive towers and Paragons, the defenses used for the boss itself are also usually enough to handle the spawns with the only limiting factor being range.

In Boss Rush, Bloonarius can be handled using towers like Sauda, MOAB SHREDR, Overdrive, Embrittlement, Destroyer or Poplust during the early game with Glaive Ricochet, Druid of the Jungle or Recursive Cluster handling the spawns. During the mid-game the defense transitions into the upgrades of the mentioned towers and finish with Super Mines and Apex Plasma Master or a Glaive Dominus.
