Bloonarius the Inflator (BTDi)

Bloonarius the Inflator is a very large boss blimp whose primary abilities are the manipulation of water magic and the spawning of lower-class bloons. He was originally seen in Bloons Monkey City, but returns to BTDi with many buffs, new abilities, and a lot more health.

Bloonarius has a single Class 4 Carrier Bay in the front, capable of rapidly spawning bloons up to the size of a BAD. The unique thing about Bloonarius is that the bloons are created directly inside the bay instead of just being held and deployed along the track. Because of this, Bloonarius is able to spawn hundreds of thousands of times more bloons than other spawning bloons (the exception being CHAOS Blimps, which can spawn a theoretically infinite number of lower tiers).

Phase 1
Bloonarius starts with 8 green Auracrysts, each with 60,000 health. All of these must be destroyed in order to progress. Each surviving auracryst increases his speed by 5%, but each auracryst destroyed increases the recharge speed of his spawning abilities by 12.5%.

The Stream
Constantly spawns an infinite stream of Fortified Lead-lined Ceramic Bloons, one per frame.

Massive Inflation
Bloonarius spawns a BAD. Pretty simple but used often.

Hyperinflation
Bloonarius spawns 20 Inflated BFBs over 5 seconds.

Chaos Summoning
Bloonarius instantly spawns one ENTROPY bloon for every auracryst destroyed.

Order 63
Bloonarius spawns 300 Inflated Fortified Tank Ceramic Bloons, sent in 3 bursts of 100 which are spaced apart by 2 seconds.

Rush of Death
Spawns one million Camo Regrow Rainbow Bloons compressed into a single space.

Yellow Infusion
Bloonarius increases his speed by 200% for 5 seconds. All bloons spawned during this time are given the Tattered property.

Chaos Infusion
Bloonarius and his auracrysts take 50% less damage from strong attacks, similar to CHAOS Blimps.

Death By Regen
Bloonarius spawns a Regrow ZOMG. Essentially, you have 2 seconds to pop all 4 BFBs inside it, otherwise you're screwed.

Phase 2
After destroying all of Bloonarius's auracrysts, his speed will be returned to normal, but his spawning abilities will now be recharging twice as fast as they did at the start, and will charge even faster based on the amount of health he has lost, up to an extra 50%. He also gains several offensive abilities.

The Legion
Constantly spawns an infinite stream of Shielded Tank Fortified Unstoppable Gunner Titanium Bloons, one every 6 frames.

Massive Inflation II
Massive Inflation will now spawn a Fortified Gunner BAD instead of a normal one and is used more often.

Grinder
Bloonarius's propellers spin extremely quickly, inflicting 2 damage per frame to any tower he comes in contact with. Affected towers will be given either the Bleeding or Burning status effect for 5 seconds, depending on whether they are organic or mechanical. The oversized propeller in his carrier bay will inflict 3x damage.

Whirlpool
All water-based towers take 50 damage plus 30% of their maximum health. Land towers placed near water take 60 damage due to the powerful waves. Water-based towers destroyed by this attack cannot be revived.

Dehydration
All towers take damage equal to 20% of their current health. Bloonarius is healed by 100 times the total damage done by this attack. This attack can overheal if he is close to his maximum health.

Defensive Perimeter
Bloonarius spawns an orbiting ring around him composed of ten million Shielded Lead Bloons.
