The best monkey in Bloons Tower Defense 6 (BTD6) is undoubtedly the Super Monkey. Its ability to shoot four different bloons with one shot makes it the most powerful tower in the game. Not only that, its upgrades make it even more versatile–popping 20 different kinds of bloons and shooting faster than any other tower.
Its ultimate upgrade, the Sun Avatar, gives it an even more powerful form and devastating capabilities. With its strength, range, speed, and power, Super Monkey remains the most popular tower and best choice for any game.
