Boss Bloons (BTD Unleashed)

The Boss Bloons from Bloons Monkey City return in Bloons Tower Defense Unleashed keeping their original stats, although their health and speed varies in normal game modes. They always first appear in Special Attack Events and do not appear in other modes until they're defeated in their respective events.

List of Bosses
All Boss Bloons first appear in the order seen in this table.

Special Attack Events
When they first appear, a message will pop up at the screen saying "X is attacking Monkey City!". After the player has seen this message, a long countdown will start and have the same effect as losing against the boss bloon when running out of time, which is losing a considerable amount of Monkey Money and at least one of each bought item. If the player loses, they have another final chance to fight the boss bloon. Winning gives the player rewards, and the defeated boss bloon will now start appearing in the normal game modes.

Normal Game Modes
They will appear and each one will take turns starting from Round 110 every 40, 30, 20, or just 10 rounds. Just like other bloons, their speed and health will increase with the progress of rounds.
