Ninja Bloon (TheFireDragoon)

Ninja Bloon is a boss that was introduced in Bloons TD 6 (TheFireDragoon) on Round 40. It can harness the power of any bloon that touches it or that it touches by stealing any ability it is, properties, ETC. Each time it harnesses the power of a bloon, it gains that respective bloon's RBE, lives lost, and gains three more hits. When it harnesses the power of a Camo Bloon, it will gain the ability to go invisible for a random amount of time up to 10 seconds. While invisible, only Ninja Monkeys can hit it. If a Monkey Sub, Meerkat, or Radar Scanner Monkey Village detect it, then Ninja Bloon will lose it's ability to go invisible.

Whenever a Ninja Bloon appears (every 5 rounds starting from Round 40), it is recommended to target them as if they're given the chance they can become powerful - a Camo Regen Bloon that has the power to go invisible for up to 10 seconds while being immune to freezing and explosives. When you defeat 15 Ninja Bloons with Ninja Monkeys, you get the achievement Ninja V Ninja.
