1.
A very powerful, fast, and normally deadly attacking move usually sought out by ninjas in the need of harm to their foe.

To properly perform a ninja kick you must:

1. Step forward with your recessive leg.
2. Lift your dominant leg by the knee.
3. Bring your leg at an angle with power into your target.
4. Say, "Hiya! I'm a ninja!"

You can perform a fake ninja punch and follow up with a ninja kick, but never fake ninja kick and follow up with a ninja punch. Not only is your leg longer than your arm, and you will most likely miss, but punches are weaker than kicks, so your target will experience pain less than what they expected, and that is not the ninja way.
