Teen Ninjas wear black, metal armor with red horns and red jumpsuits underneath. This armor comes from ordinary bras (called B.R.A.s), which they place on and press one of the nipples to reveal the armor. The armor allows ninjas to disguise their selves as other people, most commonly KND operatives.
Darkton Studios Continuity Edit
In the Darkton Studios Continuity, this group is a mercenary unit employed by the Adult Empire, having personal ties to director Vladmir Potov. The payment is said to be rather high, and membership comes with many benefits, including a good college tuition and high marks on future resumes.
This continuity creates a splinter group from these members; the Teen Separatists. These members did not want to be controlled by adults, so they broke off of the Teen Ninjas to form their own faction. When referred to in the context of the Teen Civil War, they are thus referred to as the Loyalists. Otherwise, they are simply referred to as the Teens or Teenagers, mostly by members of the KND.
