Throws Incredibly fast, 8 Shurikens per shot!
~ Official BTD6 description

Grandmaster Ninja is the final upgrade in Path 1 for the Ninja Monkey in BTD6. It is a much more powerful version of Bloonjitsu that shoots much faster (specifically one shot every 0.217s), has much larger range, greater damage (2 per shuriken instead of 1, 2 per caltrop instead of 1 with Caltrops crosspath) and shoots 8 shurikens per shot instead of 5. It costs $29,750 on Easy, $35,000 on Medium, $37,800 on Hard, and $42,000 on Impoppable.


  • It is very well advised to spam Shinobi Tactics Ninjas around the Grandmaster Ninja to maximise its bloon shredding power.
  • When deciding between adding either Path 2 (Distraction and Counter-Espionage) or Path 3 upgrades (Seeking Shuriken and Caltrops), it is best to consider what each of the paths will improve for the Grandmaster Ninja, as each path is more useful in different situations.
    • If used for popping down MOAB-Class Bloons, it is advised to use Seeking Shuriken, as it will maximise the number of hits onto the bloon, especially against grouped rushes.
    • If used for good anti-camo defense or for popping down normal Bloons well, it is advised to use the Distraction and Counter-Espionage upgrades. The sheer number of shurikens will make it easy to distract bloons, while Counter-Espionage will help decamoize bloons.
  • With the Deadly Tranquility Monkey Knowledge, the Grandmaster Ninja throws 9 shurikens further increasing its power.
  • Note that it still cannot pop Lead Bloons, so it's advised to add some towers that can pop leads and/or D.D.Ts , or even give the Grandmaster Ninja lead-popping power.
  • Using it with a 4/x/x (Stronger Stimulant) Alchemist is not recommended because it's high attack speed will make the buff wear out quickly. (This has changed as of 13.0, see below)
    • However, this does not apply to the 5/x/x Alchemist, wich will allow him to consistently pop Lead and quadruple his damage against MOAB-Class bloons while also increasing his range.
    • As of 13.0, Perma-Brew alchemist buffs the ninja less, as the damage per throw is already higher. However, Stronger Stimulant has almost full uptime on a plain Grandmaster Ninja due to to an attack speed decrease.
  • The Grandmaster Ninja attack speed is about 2 times faster than Ninja Discipline or 3 times faster than the base tower.
