Bloonarius the Inflator is probably the most well known Boss Bloon of BTD5. Bloonarius is the joint first Boss Bloon in BTD5 Mobile/Steam. Today we will show you how to beat him if you are playing Mobile or Steam.


Also note that he looks like a very fat BFB with no angry eyes, but widened out ones instead. He also has more wings and is a different color.

Bloons Tower Defense 5 Mobile/Steam Edit

Bloonarius the Inflator is a Boss Bloon. He is common and appears once every 4 hours (not 100% definite if other Bosses appear) and rewards you with a Random Item upon beating him. He is covered in Swamp like stuff.

Info Edit

He is a Boss Bloon. His ability is that every time a Skull is passed on the Health Bar, he summons a Lead Bloon to fight. This can be CATASTROPHIC for 0/3 or 1/3 Spike Factory users, as the Lead Bloon clears out all the MOAB-SHREDR Spikes, and allows Bloonarius to pass on through scot-free. 2/3s are recommended. You can counter this as shown below. He is stronger than a BFB (estimate). It is more of a challenge in BTD5 because no Bloon Beacon powers which could kill him with the click of a button. He will never appear in natural BTD5 freeplay. He only appears in designated Boss spawn times.

Strategies Edit

If he appears on a map with water, attempt multiple x/1 Monkey Buccaneers. A 3/1 could work too, but you need $2500+. If on land, attempt a Heli Pilot and Dart Monkey. Get a 2/3 Spike factory instead of a 1/3 or 0/3 if you plan on using Spike Factories. This is to deal with the Lead Bloons. If you can afford it, you can do as much damage as possible at one point, then buy a quick x/4 Bomb Tower and activate the MOAB Assassin ability to kill him instantly if you get his HP down enough. Another strategy is to get towers that can kill Bosses with ease. Try the Spike Factory if you are brave enough. He moves at a Red Bloon speed too. He has 2000 HP.
