Rebel Bloons

Or rather so... 'Bloons Tired of Being Treated As Bloons'. You'll get what I mean in a minute. The Rebel Bloon is more a property than a Bloon, but there's enough to it to make a page based around it.

What It Does
How It Happens: Upon beating The Hidden Dark Continuity, in any mode after (Freeplay, Special Missions, etc.), every bloon spawned has a 0.05% chance of being a Rebel Bloon.

Appearance: Bloons that are 'rebellious' have a sword stamped on them, with a golden handle.

Specialty: Rebel Bloons will deal 1 layer of damage to every bloon it touches on the path, but also sacrifice one layer to do so. If a Rebel Red Bloon hits a Blue Bloon, the red will pop, and the blue will become red. There is also a 5% chance the Rebel Bloon will turn the touched Bloon into a rebel, and sacrifice no layers.

Why Even?
In the 'lore' if you so please to call it, upon the end of the Hidden Dark Continuity, a new government is put in place. This sub-story is not canon to the whole 'Zathus Timeline' we shall say, but bear with me. In this continuity, the Rebel Bloons oppose the new government, and rightfully so pop the bloon soldiers combatting the monkeys.
