The monkey ninjas served Monkey Fist in a variety of capacities, though were first and foremost his initial wave of attack in combat. This strategy was often set into motion with the battle-cry, "Monkey ninjas attack!", and Monkey Fist would then only enter the fray once they had either proved unsuccessful, or he simply lost his patience. The monkey ninjas were highly effective against the unprepared, as most people reacted to the sight of them with either fear or hesitation.
Outside of combat, the monkey ninjas acted as Monkey Fist's assistants, and he presumably trained them in this as well. Monkey ninjas were seen carrying his luggage, driving his vehicles (unsuccessfully), and threatening people on his behalf.
Base of Operations
After Lord Monty Fiske's transformation into Monkey Fist and his first failed attempt at grasping power, he replaced his former valet Bates with a team of highly trained monkey ninjas.
After hearing that Ron was the Ultimate Monkey Master—as later confirmed by Master Sensei—the Monkey Ninjas abandoned Monkey Fist for Ron, freaking him out. They, or possibly another group of individuals, eventually returned to Monkey Fist for an unknown reason.

In Monkey Ninjas In Space, they found out that Ron Stoppable is the prophesized Ultimate Monkey Master and their leader. For a short period, they were following him everywhere, but the next time that Monkey Fist was seen, they returned to support Monkey Fist instead. It is unknown if these are the same Monkey Ninja from the previous episode, or if Monkey Fist trained a new troop.
